Phase Shifting Strategy for Mitigation of Local Voltage Rise in Highly PV Penetrated Distribution Network

The polluting nature of conventional sources is leading the world toward non-polluting renewable energy sources. Solar Photovoltaic (PV) technology is considered to be the future of energy. Small-scale rooftop plants are favorable for the fulfillment of consumer demand and generating revenue from surplus energy. Traditional distribution systems face power quality issues as a result of rooftop solar plant integration. For distribution networks with high PV penetration, Local Voltage Rises and reverse power flow (RPF) are major concerns. In this work, the author has proposed a Phase Shifting Strategy (PSS) for mitigation of Local Voltage Rises and Reverse Power Flow. Under high PV penetration, the IEEE 906 Bus European LV Test feeder was investigated. Co-simulation using OPENDSS and MATLAB has been performed to validate PSS in solving Local Voltage Rise and minimizing Reverse Power Flow issues. The results show that the voltage profile of all the consumers is significantly improved with the PSS.
