The proposed system is used for Voltage Regulation and Reactive Power Compensation of the transmission system. It consists of reactor banks, arranged in binary order steps with fixed capacitor is referred as FC-TBSR. Normally we use SVC (TSC+TCR) for reactive power compensation and voltage regulation. But this type of SVC has some inherent drawbacks such as harmonics, more losses in TCR, SVC required the additional filter for harmonic reduction, the cost of SVC is more due additional Filter. To avoid these drawbacks a new FC-TBSR compensator has been proposed.

The reference current generation technique consists frequency domain method that uses Goertzel Algorithm. The second method used for comparison is Enhanced Phase Locked Loop (EPLL). The Goertzel Algorithm and Enhanced Phase Locked Loop are used to extract the fundamental component of load current. The extracted currents are used for generation of template currents for reference current generation. The shunt active power filter is implemented using these two methods and investigated for three phase balanced and unbalanced loads using MATLAB/Simulink. The methods are investigated for transient conditions, computations and the results are compared for effectiveness of the above methods under different conditions.

A comprehensive static VAR compensator consisting of capacitor bank in five binary sequential steps in conjunction with a thyristor controlled reactor of smallest step size is employed in the investigative work. The work deals with the performance evaluation through analytical studies and practical implementation on an existing system. A fast acting error adaptive controller is developed suitable both for contactor and thyristor switched capacitors. The switching operations achieved are transient free, practically no need to provide inrush current limiting reactors, TCR size minimum providing small percentages of nontriplen harmonics, facilitates stepless variation of reactive power depending on load requirement so as maintain power factor near unity always.

The thyristor binary switched reactor contains thyristors which are connected in antiparallel which acts as bidirectional switch in series with a reactor and fixed capacitor connected across. The reactor banks are arranged in binary steps. Usually, FACTS devices are used for voltage regulation and reactive power compensation but it has some drawbacks like harmonics injection and it will not give fine voltage control because it has fixed values. To avoid and overcome these drawbacks, a new FC-TBSR compensator has been proposed.

Their performances are evaluated based on their voltage support, dynamic response, losses, cost, and additional filter requirement, if any. In this paper, efforts are made to improve the dynamic performance parameter such as rise time, settling time, and peak overshoots. A new topology with an adaptive controller is presented, in which capacitor and reactor banks are divided in their binary values and connected in the shunt. Capacitor and reactor banks are operated by thyristorised switches. Both these banks are operated in closed-loop form as a cascade control. Amongst these, capacitor bank operates as coarse control, and reactor bank acts as fine control. For the performance enhancement, a model reference adaptive controller is used. The system identification toolbox is used to evaluate the mathematical model of the plant with Matlab. The model's performance was analyzed deeply by the adaptive controller with different reference models such as critical, under, and overdamped. The performance parameters such as rise time, settling time, and peak overshoot in the form of reactive power swings, are evaluated and plotted for different adaptive gains using MIT rules.

Large scale incorporation of non-linear loads has the potential to raise harmonic voltages and currents in an electrical distribution system to unacceptable high levels that can adversely affect the system. Active power filter (APF) based on power electronic technology is currently considered as the most competitive equipment for mitigation of harmonics and reactive power simultaneously. Instantaneous power theory is used for generation of reference current. This paper presents a comparative study of the performance of three current control strategies namely ramp comparison method, hysteresis current controller (HCC) and Adaptive hysteresis current controller (AHCC) is carried out and superiority of AHCC is established. Simulation results for all the method are presented using MATLAB/SIMULINK power system toolbox demonstrating the effectiveness of using adaptive hysteresis band.

Distributed energy resources (DER) interfaced with Z-source inverter (ZSI) using right control are capable of providing dynamic voltage regulation near the load end user. This paper presents Z-source inverter interfaced with proton exchange membrane fuel cell (PEMFC) connected to grid can boost DC voltage to supply voltage regulation dynamically, in particular with application of adaptive voltage control algorithm with double carrier pulse width modulation control. The simulation results in different system condition show that Z-Source inverter with PEMFC is capable of proving dynamic voltage regulation without using boost converter. Since this system has advantages over two stage conversion with boost converter and voltage source inverter as it reduces system cost and increases overall efficiency of system, it is very suited for utility application.
