Analysis of load flow and short circuit on PV penetration at GI Medari feeder 3 Yogyakarta

PV has been used throughout the year in several areas in Indonesia due to the high potential for solar radiation. It is currently being used both in stand-alone models and in energy generation models where photovoltaic cells are connected to an existing grid. PV can be used and developed in the Yogyakarta region, especially in the GI Medari because it has a radiation value of approximately 1608/kWh/m2/year. With high enough iradiation, the placement of PV in the right location in the system will maintain the voltage utility, but if PV is placed in the wrong location, it will affect the stability of the system. When PV is connected to a strategic location, the system will be more stable. The purpose of this paper is to analyze the effect of PV entering the system with different penetrations by looking at the load flow and short circuit system before and after adding PV to the GI Medari system, the 3rd feeder (MDI3) with 217 buses, using ETAP (Electrical Transient Analyser Program) 12.6.0
