Placement of photovoltaic and capacitors in the 20 kV Jeneponto Distribution Network

Abstract

Indonesia is located on the equator which has a good intensity of solar radiation throughout the year. This radiation condition gives the potential for photovoltaic placement in Indonesia. Jeneponto Regency is one of the areas in South Sulawesi that has the high potential for the construction of photovoltaic (PV) with irradiation levels reaching 5.404 kWh/m2/day. This research aims to determine the location of photovoltaic and capacitor interconnection points in the 20 kV Jeneponto distribution system for optimizing voltage stability and minimizing power losses. The optimal simulation of the determination of interconnection points is carried out by simulating photovoltaic placement in different main buses, which are Jeneponto main distribution substation, Jeneponto switching substation, Tolo switching substation and Benteng switching substation. The results analysis showed that the photovoltaic interconnection point in Benteng switching substation produces the smallest power losses and all loads have a voltage profile that complies with both IEEE and PLN voltage standards.
