Efficient Power factor improvement with SVC based on the PI controller under Load Fault in the smart grid

摘要

in this paper, to improve the power quality and the efficiency, the power factor correction in the system is done by using SVC (Static Var Compensator) in load transient condition. The SVC is used TCR (thyristor controlled reactors) and TSC (thyristor switch capacitor). The system power factor is become constant by using SVC in the PCC (point of common coupling), where it is changed dramatically in different load conditions. To obtain the best power factor in the system, the PI controller is used to check the necessary reactive power by connecting the capacitance and the reactance to the PCC with TSC and TCR respectively. The simulation results are displayed with MATLAB/Simulink to verify the effectiveness of the proposed algorithm.
