Abstract: This paper addresses Power Quality (PQ) issues that prevail at point of common coupling (PCC) of Photo Voltaic (PV) system integrated to the Distribution System. The system considered for the analysis is IEEE-13 nodes test feeder network integrated with PV and D-STATCOM. A novel fuzzy logic controller (FLC) proposed dynamically controls the gate pulse patterns of D-STATCOM, in turn providing flat voltage profile D-STATCOM is the Voltage source inverter (VSI) also provides reactive power support to the distribution system. PQ issues voltage sag, swell and interruptions are mitigated by the proposed robust FLC by generating gate pulse values considering deviation in voltage as input. Membership functions defined are used to set fuzzy rules thereby determines the firing pulse corresponding to the voltage values sensed at PCC. The proposed control algorithm is tested on IEEE 13 bus distribution system with PV integration in Simulink environment. The results indicate the effectiveness of the controller in reducing error less than 5% and maintaining the voltage near to 1.0 per unit.
