Abstract

Electric vehicle is regarded as the backbone of future transport system. The key inputs to electric vehicle technology are climate change, emission-free zones, growing mobility, higher efficiency, rising prices of fossil fuels, etc. The batteries of plug-in electric vehicles may be treated as an energy source capable of drawing excess energy and delivering the same to fulfill the load demand. Ancillary service in the form of frequency regulation is an important aspect of grid and is continuously exercised in order to maintain balance between generation and the load demand. The power from conventional and renewable sources determine the generation capacity. The gap between generation and load demand can be fulfilled using batteries of electric vehicles parked with the aggregator. The chapter describes the capacity estimation by the aggregator and energy management strategies well in advance for bidding price and the commercial value of electric vehicle for executing bidirectional power transfer between vehicle and the grid. The various approaches of capacity estimation by the aggregator listed in this chapter contribute to the grid in the process of frequency regulation, thus relieving the conventional generation thereby increasing their useable life.

Abstract

High farad values of ultra capacitors (UCs) are associated with very large current during charging. This paper proposes numerous switching configurations within ultra capacitor units supplying energy to load in efficient way. This reconfiguration dealt with series–parallel connections with reference of load voltage maximum and minimum limit. By using proper switching, 99% of stored energy can be delivered to load in minimum time. In normal case, only 73% stored energy could be utilized by load. Proposed scheme shows that operation will become faster, i.e., 57.67–75.68%.

Abstract

This paper is based on the basic performance analysis of Distributed Static Series Compensator (DSSC) required for the improvement of power system stability. The DSSC has small size and weight with cylindrical structure that is put on the line conductor without grounding. It has the capability of changing the impedance and altering the power flow through the lines. The fundamental behavior of DSSC and Static Synchronous Series Compensator (SSSC) is similar. However, a DSSC costs less and higher reliability. In this paper, single machine infinite bus system (SMIB) has been simulated in PSCAD for various operating conditions of power system such as steady state and during fault conditions.

Abstract

This paper presents the result of the two-dimensional finite element analysis on the effects of rotor pole arc variation and number of teeth per rotor pole with different teeth depths and stator excitation pattern on various performance parameters like cogging torque, developed torque, harmonic torques, torque ripple and phase inductance for an 6/8, three phase flux reversal motor. A novel excitation pattern of exciting each phase for one step with positive and negative excitation in one rotor pole pitch resulting into higher torque per ampere is presented. Three teeth per rotor pole with the teeth height of 2.5% of the pole height reduces the torque ripple by 37.31% with the average torque reduction of just 5.36%.

Abstract

In this paper, a prototype model of high voltage direct current transmission system is developed using six pulse converter. This consists of two six pulse converters connected through transmission line resistance and smoothing reactor. One converter operates as a rectifier and other as line commutated inverter. The simulation study is carried out using simulation package of PSIM to predict the performance of system under various triggering angle conditions. Different types of triggering schemes are also simulated to see the performance of system. Simulations related with power reversal mode, impact of fault on system are also simulated. A laboratory prototype is developed to validate the simulation results. Thyristor trigger logic is developed and implemented for both converters. The control scheme is implemented using Arduino Uno development board. The system behaviour is validated under normal operating conditions.

Abstract

The paper entails simulation of prototype model of HVDC transmission system. This involves the design of converter circuitry, gate firing units, rectifier and inverter control systems and gamma detection circuits. The complete model converts AC power into DC power by controlled rectifier and then converts this DC power into AC power by line commutated inverter, after transmitting DC power through the line. There are three basic controls namely Constant current, Constant extinction angle and Constant ignition angle control required for prevention of large fluctuation in DC current due to variation in AC system voltage, maintaining DC voltage near rated value and prevention of commutation failure in inverter. This paper aims for Conversion of power, Bi-directional power flow on HVDC link and behavior of HVDC link during fault occurrence and fault clearance are main objectives of this paper. Simulation of complete HVDC transmission system for 3 kW, 415 V, 50 Hz system is done in PSIM (9.0.3) software. Thus, complete simulation model of prototype HVDC system is developed using the basic concepts and appropriate circuitry.

Abstract

Two high voltage direct current transmission line circuits have been simulated in the PSIM software, one employing the Individual Phase Control scheme and the other, Equidistant Pulse Control scheme. This paper presents the circuitry employed in the two simulations and the results obtained from both. It is shown that the circuit employing the former scheme suffers from an excess of non-characteristic harmonics when operating with a weak AC system whereas the latter can work on weak AC systems without problems of harmonic instability because it generates firing pulses independent of the AC source. The implementation of the two schemes clearly demonstrates how one is dependent on the feedback from the source whilst the other utilizes a Phase Locked Loop to circumvent this problem.

Abstract

This paper presents an improved multilevel module multilevel inverter (IMLM - MLI) fed threephase induction motor drive. Proposed topology is configured for 11 level inverter with IGBT based bidirectional blocking-bidirectional conducting switches and unidirectional blocking-bidirectional conducting switches. This converter topology fed induction motor drive is controlled by open loop as well as closed loop scalar control methods with proportional plus integral (PI) controller. The proposed converter topology significantly reduces switching device count, switching power losses and gate driver circuitry. This topology switching is controlled by variable frequency multi carrier sinusoidal pulse width modulation technique (SPWM).

Abstract

Power quality is the major concern in today's electrical power system. Especially, power quality problems are continuously observed in distributed electrical power system. Mainly the voltage quality is the major aspect in distributed electrical power system. Voltage sags and voltage swells are the main parameters on which the improvement is needed. Voltage quality can be sufficiently improved in distributed electrical power systems by using some custom power devices such as dynamic voltage restorer. The Dynamic Voltage Restorer (DVR) is fast, flexible and efficient solution to voltage sag and voltage swell problems. The DVR is a power electronic based device that provides three-phase controllable voltage output, whose voltage vector-magnitude and angle-adds to the supply voltage during sag event, to restore the load voltage to pre-sag conditions. And when voltage swell occurs DVR injects 180° out of phase voltage into the line. The DVR is designed for protecting the whole plant with loads in the range of some MVA. The DVR can restore the load voltage within few milliseconds.

Abstract

For efficient performance of any vector controlled drive, motor parameters are to be estimated with utmost accuracy. Offline and online parameter estimation techniques are generally used for estimating parameters. In this paper, the offline technique is adopted due to its advantage over latter technique. Under offline parameter estimation, the new strategy is simulated for estimating the machine parameters. Inverter test and single phase test are used for estimating parameters. Only three switches of the inverter are used for estimating parameters in inverter test and four switches in single phase test. These tests are easy to implement with no extra hardware, no mechanical job is required and equations are easy to understand and implement. These tests are simulated in MATLAB Simulink and parameters obtained are compared with actual parameters of machine model available in MATLAB Simulink.

Abstract

AC-AC power conversion particularly for speed control of AC drives is done with single phase cyclo-converters. In this work the single-phase matrix converter (SPMC) topology is used as a cyclo-converter. IGBT are used as power switches. The sinusoidal pulse width modulation has been used for generation of pulses. This paper presents three different switching strategies for SPMC. A comparison is made between these three strategies based on parameters such as type of load to which the strategy is restricted, number of switches kept ON during single time interval, output voltage waveform of SPMC and its THD.

Abstract

This paper presents behavior analysis and digital implementation of current error space phasor based hysteresis controller applied to three-phase three-level flying capacitor converter as front-end topology. The a controller is self-adaptive in nature and takes the converter from three-level to a two-level mode of operation and vice-versa, following various trajectories of sector change with the change in reference dc-link voltage demanded by the load. It keeps current error space phasor within the prescribed hexagonal boundary. During the contingencies, the the proposed controller takes the converter in overmodulation mode to meet the load demand, and once the need is satisfied, controller brings back the converter in normal operating range. Simulation results are presented to validate the behavior of the controller to meet the said contingencies. Unity power factor is assured by the proposed controller with low current harmonic distortion satisfying limits prescribed in IEEE 519-2014. Proposed controller is implemented using TMS320LF2407 16-bit fixed-point digital signal processor. Detailed analysis of numerical format to avoid overflow of sensed variables in processor, and per-unit model implementation in software are discussed and hardware results are presented at various stages of signal conditioning to validate the experimental setup. Control logic for the generation of reference currents is implemented in TMS320LF2407A using assembly language and experimental results are also presented for the same.

Abstract

This paper presents analysis of two-level front-end converter employing current error space phasor-based hysteresis controller. In general, for such current controllers with inner and outer bands, the current error space phasor moves out of inner boundary six times in fundamental cycle for sector change detection. This deteriorates shape of line current waveform. In the proposed work, sector change detection logic is developed and implemented, which uses information of instantaneous values of three line voltages. It does not demand outer hysteresis band and lookup table to detect sector changeovers. This results in improvement in waveshape of line current. Proposed controller is also tested with different dynamic conditions like load variation, overmodulation, reverse power flow and line side variations, and the results of unity power factor and low total harmonic distortion in supply side current are presented. Conventional hysteresis controller is implemented using TMS320LF2407A DSP processor, and the results are discussed for unity power factor.

Abstract

Solid state rectification of ac power using diodes and thyristors are drawing harmonic current and reactive power from ac supply and behave as non-linear load. During unbalancing of the three-phase supply voltage causes excessive neutral current, which results in to low power factor, derating of equipment, poor efficiency and initiate triplen order harmonics. These all will raise serious issues related to power quality of the supply sys-tem. With the aim of mitigation of the same, the shunt active power filter is selected and analyzed with a synchronous reference frame control algorithm. This paper mainly focuses on the performance analysis and simulation of a shunt active power filter. The performance analysis of the filter in terms of reduction in %THD as per IEEE-519-1992 standard and unity power factor at the line side for various dynamic conditions. The proposed scheme is simulated and validated in MATLAB/Simulink environment for various steady state and dynamic condition.

Abstract

A dc-dc converter has its applications, such as in hybrid vehicles, solar inverters, in power supplies for microprocessors etc. A bidirectional dc-dc converter can be alternately operated as a step-down converter in one direction of energy flow and as a step-up converter in reverse direction of energy flow, in places where both the sides have voltage sources. A high voltage supply using a single converter is not preferred as it leads to high ripple in output voltage and current, thus requiring a large value of inductor and filter capacitor. To overcome these limitations multiphase interleaving technique is used in bidirectional dc-dc converters i.e. connecting the converters in parallel with the switching instants equally distributed among them. This paper presents a comparative study of the single phase and multiphase bi-directional dc-dc converter and the optimization of inductor and filter capacitor. The open loop simulation is done using Simulink tool and conclusions are drawn.

Abstract

During the last two decades, the electricity distribution sector in many developing countries including India has undergone a wave of reforms, seeking to transfer the productivity gains to consumers and to improve the efficiency of utilities. A widely favored approach in assessing potentials for efficiency improvements is through benchmarking of utilities based on their relative efficiency. In essence, benchmarking identifies the most efficient firms in the sector and compares the actual performance of less efficient firms against the reference performance of most efficient firms. The study aims to evaluate the technical efficiency on a panel-data of 59 electricity distribution utilities in India employing the parametric approach namely Stochastic Frontier Analysis.

Abstract

Since the 1990s, India has adopted a number of measures to reform its electricity sector as in many countries around the world (Jamasb et al., 2017). The main objective of electricity reforms is to provide utilities with incentives to enhance their efficiency both in terms of operation and investment. The aim of the sector regulator is to ensure that consumers benefit from the achieved efficiency gains. In India, the enactment of the “Electricity Act, 2003” was aimed at improving the efficiency of the sector. Improving the efficiency of the electricity distribution utilities through incentive-based regulation mechanisms is a central component of most electricity sector reform. At the same time, it is generally accepted that the quality of institutions affects the economic performance of developed as well as developing countries (see, e.g, Acemoglu et al., 2002). India is a good example in case where the quality of institutions vary across the different states and the absence of transparency and unproductiove institutions often manifests itself in the from of corruption leading to economic inefficiency (Thakur et al., 2004). However, there is scarce empirical evidence in the literature of the effect of quality of institutions issue on the performance of the electricity distribution sector. In order to fill this gap, we use a novel dataset prepared for this study and analyse the cost efficiency of the Indian electricity distribution utilities in different states while detrmining the effect of quality of institutions on their efficiency. This approach to efciency analysis can help sector regulars develop better incentive regulation schemes.

Abstract

With regulators’ growing interest in improving operational efficiency and quality supply, the time is nearing when performance based regulation will become norm for regulating the distribution tariff in Indian electricity distribution sector. In this context, the State Electricity Regulatory Commissions proposed replacing rate-of-return regulation with most commonly used performance based regulatory regime i.e. Price Cap regulation also known as RPI-X (Retail Price Index – Productivity Offset) regulatory framework. However, the potential problem associated with applying price cap regulation scheme in practice is the determination of productivity offset or X-factor used in price caps setting. This paper proposed an approach to calculate the X-factor for 58 government-owned and privately-owned electricity distribution utilities in India during a five year period from 2007/08 to 2011/12. A Stochastic Frontier model through an input distance function is first applied to compute the Malmquist Total Factor Productivity (TFP) and the estimated TFP is then used to calculate the utility–specific X-factor. With rely on calculated X-factor, the distribution utilities would be able to cap either on prices or revenues thus accounting the inflation in the tariff determination. This will be more realistic approach as compared to cost plus approach.

Abstract

In Indian electricity supply industry, the state electricity regulatory commissions presently follow rate-of-return regulation for setting the retail tariff for distribution utilities. However, the current approach of tariff determination does not guarantee any incentives to the utilities to reduce their operating costs and often leads to arbitrary decision making. Accordingly, a performance-based regulatory mechanism has been recognised as an alternative approach to the traditional rate-of-return regulation and most of the state electricity regulatory authorities are now in the process of implementing performance-based regulation regime for setting the distribution tariff. This paper analyses the cost efficiency of 58 Indian electricity distribution utilities during the period 2008/09-2011/12. The estimated 'best' practice frontier could be used by Indian state electricity regulatory authorities as a benchmark to control utility's cost and further could be served to provide preliminary base for implementing performance based regulation in Indian electricity supply industry.

Abstract

Indian power sector has witnessed significant progress in recent times particularly in generation and transmission. However, the distribution licensees today are facing different challenges in terms of huge financial losses caused by several factors including inadequate tariff, high aggregate technical and commercial losses, operational inefficiencies, regulatory infirmities etc. Thus, there is a need to effectively assess the efficiency and overall performance of distribution utilities and provide solution for improvement. The present study analyses the performance of 59 Indian electricity distribution licensees (including both public and private owned) by working out the technical efficiency using the mathematical model of Stochastic Frontier Analysis (SFA). In the present research, the authors estimated a translogarithmic inefficiency effects stochastic frontier model using consumer density, consumer structure and distribution loss as determinants of inefficiency. The quantitative estimates obtained from the production function shows the mean technical efficiency score of 0.81 indicating that on the average, the electricity distribution licensees were able to obtain about 81% of potential Vol 22, No. 1;Jan 2015 230 office@multidisciplinarywulfenia.org output from a given mix of inputs and there was 19% allowance for improving efficiency of electricity distribution utilities. This framework would be practical for policy makers and individual state electricity regulatory commission to rank their distribution licensees and formulate performance based incentive mechanism to improve their operational and financial performance.

Abstract

Today’s Electricity Supply Industry across the world is undergoing enormous changes due to restructuring process and India is no exception for this. Traditionally, electric power systems throughout the world has long been dominated by single vertically integrated utilities for supplying electric power to various consumers based on cost of service. Individuals working on restructuring strongly believe that deregulation in electricity industry will create new business opportunities and new technologies such as metering and telecommunication devices will develop. With VIUs framework, transmission pricing is not important since there is no need to separate its cost from the utility company’s total cost of power system delivery. However, as we march from Vertically Integrated System to competitive electricity, transmission price becomes a major issue for power system engineers. Since an electron cannot be coloured, there is no standard formula to compute wheeling charges within the Electricity Supply Industry. This paper addressed several commonly used transmission pricing methods adopted by Public Utility Companies.

Abstract

In the Indian Power Sector, The Electricity (Supply) Act, 1948 made the beginning for rationalization of the production and supply of electricity including pricing. Pricing of power generation, transmission, distribution and supply passed through various phases since then with emphasis always on protecting the interest of consumers and supply of electricity to all areas. The Electricity Act, 2003 was a major step for taking measures conductive to development of electricity industry, promoting competition therein. It made provisions for freedom to all players in many fields, including sale of power by generating companies to any person, transfer of surplus power by captive power plants to any other place for their own use or sale of surplus power to others, purchase of power by the consumers from any source, opening of transmission sector for private investment, trading of power etc. In view of the fact that the power flows by displacement and the power system operates in the integrated manner, it made provision for open access to be provided by the transmission and distribution licensees. Transmission of power is a capital intensive activity and its pricing is vital for operation of Power Sector with commercial approach. Integrated system operation and flow of power by displacement makes the transmission pricing a complex problem that may have no straight answer and any system of transmission pricing would have its own strength and weakness. This paper deals various transmission pricing approaches that may fit best to the Electricity Supply Industry.

Abstract

Multi-level inverters have found wider scope of applications in medium as well as high-power adjustable-speed drives (ASDs) due to their capability of handling high powers and power quality friendly approach. For efficient control of ASDs, indirect vector control is used which has advantages like; elimination of retrofitting of shaft encoder, faster dynamic response, and low torque pulsations. Carrier less modulation techniques (e.g., space vector pulse width modulation) provide more maximum peak fundamental output voltage in linear range of modulation for multi-level inverters. However, carrier based control schemes provide simpler control and more flexibility in operation of the control, especially for dc-link capacitor voltage balancing. This paper focuses on analyzing performance of indirect vector control of induction motor, for phase disposition type of multi-carrier technique. Steady-state as well as dynamic performance of the three-level inverter based drive is analyzed by simulation studies. For experimental validation, hardware set-up of three-level neutral point clamped inverter controlled induction motor drive is developed using Arm Cortex ST32F4 in open-loop configuration. Experimental results depicting satisfactory operation of the developed drive in steady state are presented in this paper.

Abstract

Efficient and Adaptive Artificial Neural Network (ANN) based Shunt Active Power Filter (SAPF) for mitigating harmonics is presented in the paper. ANN based reference current generation is implemented using Neural Synchronous method while Levenberg Marquardt method is used for training algorithm. ANN based Space Vector Pulse Width Modulation (ANN-SVPWM) controller is realized for the effective control of SAPF. Performance of the proposed ANN-SVPWM controller is compared with conventional Hysteresis Current Controller (HCC). Hence, both the reference compensating currents as well as controller of the proposed SAPF are realized using Artificial Neural Network. Effective compensation of the load harmonics and good dynamic response of the ANN based SAPF is proved by the presented simulation results using MATLAB. The proposed SAPF effectively compensates for the load harmonics in steady-state as well as during dynamic conditions.

Abstract

Current error space phase based hysteresis controller requires two (inner and outer) hysteresis bands for vector selection and for sector detection, respectively. Current error space phasor moves many times out of the fixed hexagonal boundary (and touches outer hysteresis band) in one fundamental cycle to detect appropriate sector. This distorts the supply current and increases the implementation complexity. In this paper, fractal approach and triangularization techniques are proposed and analyzed to eliminate outer hysteresis band and look-up table for sector change detection. This technique is integrated with current error space phasor based hysteresis controller to make it generalized for any multi-level front-end converter. Detailed analysis of the proposed technique for sector detections is presented considering voltage space phasor structure of three-level and five-level converters. Generalized flow chart is also developed and presented for any multi-level converter employing current error space phasor based hysteresis controller with proposed sector detection technique. Experimental results for various steady state and dynamic conditions are presented to validate the technique of sector detection, considering voltage space phasor structure of threelevel flying capacitor (FC) front-end converter.

Abstract

Conventional technique of eliminating current harmonics by use of passive filters suffers from drawback of series and parallel resonance within the network impedance, overcompensation of reactive power at fundamental frequency and poor flexibility. Shunt active power filters (SAPFs) are conventionally used to reduce current harmonics. The active harmonic filters introduce compensating currents into the source to mitigate the harmonics injected by the load current. The compensating currents will be derived by sensing three-phase voltages at the Point of Common Coupling (PCC) and load currents. This paper analyzes fast Fourier transform algorithm, instantaneous reactive power technique, and synchronous reference frame technique, to derive the reference compensating currents. The generated reference compensating currents act as reference for actual compensating currents for the fixed switching frequency based current controller which generates switching signals for the SAPF employing three-level T-Type Neutral Point Clamped (TNPC) topology of converter. Simulation studies for the presented SAPF is carried out using PSIM software. Hardware set-up of the presented SAPF is implemented using DSP TMS320F28377D.

Abstract

Due to low-cost and high-reliability, induction motors have discovered significant applications for variable speed applications. The vector control method is used to achieve better dynamic response and use of induction motor for a wide range of speed variations. However, it uses shaft encoder for rotor speed estimation that suffers from added cost, measurement noise, and maintenance associated with them. To overcome these shortfalls, speed is estimated with the help of measured voltages and currents in sensorless vector-controlled drive. The rotor speed estimation method is based on a direct synthesis of induction motor state equations. Simulation of the drive is carried out using PSIM software. In order to validate the method, laboratory prototype is developed using DSP TMS320C2811 for 10 H.P. and 15 H.P. squirrel cage induction motor.

Abstract

With the increasing energy power demand, optimum utilization of energy is the need of the day. Unified Power Flow Controller (UPFC) because of its unique capability to control both real and reactive power has become popular device for maintaining and controlling the power system parameters. This is done by controlling voltage, line reactance and phase angle. It also facilitates loading transmission lines near their thermal limits. These abilities of UPFC make it a unique device for providing flexibility to power system operators. The application of proposed control scheme for investigating the role of UPFC in power transmission lines is studied by using Space Vector Pulse Width Modulation Technique. To explain the control and conditioning of power (both active and reactive), simulation of the system is carried out in MATLAB simulative environment. The system is studied under various steady and transient states, at various load demands. The dynamic controllability of the demand variation is also studied in the simulation environment.

Abstract

Three-level inverters are very appropriate for high-power adjustable-speed drive applications. In conventional inverter quality of voltage and current is poor it is because of presence of harmonics so, because of harmonic there is significant level of energy losses. In three level inverter harmonic content is less compare to the conventional inverter and the %THD is also less. This paper represent simulation of indirect vector control of induction motor fed by the three level inverter. In industrial application indirect vector control is wildly use. With vector control the Dynamic response of the motor is very fast, and motor can give constant torque for variable speed and variable torque for constant speed. The problem associated with conventional scalar control drive like poor dynamic response, limited speed range can be solve by this scheme. In this paper for implementation for indirect vector control fuzzy logic control technique is use. Fuzzy logic technique is very use full for the high performance speed drive.

Abstract

Renewable energy sources are becoming an integral part of existing and future grid due to their clean and sustainable nature. A gridtied renewable energy system is preferred over stand alone as it provides better utilization of generating power as they do not require an energy storage system, renewable energy sources such as Solar Cell, Fuel Cell, and Battery energy storage system need a power inverter for grid interconnection. Different pulse width modulation methods control these inverters. Sinusoidal PWM technique is commonly used where Total Harmonic Distortion is to be reduced. But, the presence of side band harmonics due to Sin-Pulse Width Modulation appearing at multiple of carrier frequency creates the problem of acoustic noise, Electromagnetic interference, and torque ripple in the associated system. An effort has been made in the present work to reduce the sideband harmonic effect by random Pulse Width Modulation techniques. The conventional random PWM method is investigated with simulation. A novel application of random carrier frequency PWM method based on the interpolated triangle wave proposed in the present work. The result shows that the proposed method gives a better harmonic spectrum and reduces Total Harmonic Distortion.
