Performance Analysis of Grid Integrated PV System using SRF and IRPT Control

With the increase in grid connected PV based generation, degradation of power quality at the point of common coupling (PCC) has become a serious issue both for electric power utilities and consumers. Improvement in power quality is achieved through power factor correction, reactive power compensation and harmonic mitigation using different control techniques. This paper presents the performance analysis of grid integrated PV and addresses the power quality issues using synchronous reference frame (SRF) and instantaneous reactive power theory (IRPT) technique for inverter control. A 10 kW grid integrated photovoltaic system has been developed. Simulation of developed model is carried out on MATLAB/Simulink.
