Abstract :
Indonesia is a country with the use of fossil energy, such as BBM and coal are still at the top of the list as primary energy resources at the power plant. This load flow analysis research aimed to optimize the output power of the Cirata PLTS system. This research used software Electric Transient Analysis Program (ETAP) and Photovoltaic System (PVSyst). ETAP was used as first simulation to get power flow. At the same time PVSyst was used as second simulation to get optimum power. With a flow rate of 100% with simulation using ETAP software also obtained voltage that occurred on the bus 380 V / 400 V and 20 kV had the same value on each bus it was 380 V and 20 kV. Based on the result of the simulation of PVSyst was known string inverter with difference of PV power ratio in the amount of 27,79% and AC power of 27,90% was superior compared with the central inverter which had a comparison difference is lower with PV power of 26,17% and AC power of 26,11%. The less optimal power possessed by environmental factors, dust on the surface of PV, and weather.The weakness of Cirata PLTS load flow system can be solved by adding energy storage, in accordance with the data obtained on the field that the average power which generated in discharger process is 49,9 kWh. The additional power became backup to keep the power stability of the two inverters.
