Abstract:

At present the need for AC power loads is increasing in accordance with the increasing population. This is due to the increasing electrical load that requires an AC power source. In addition, fossil fuels are getting less and less and many power plants use these fossil sources. Indonesia is a country that has abundant sources of renewable energy, so that microgrids can be developed. In the microgrid system, the inverter is used to convert DC voltage to AC voltage. The purpose of this research is to increase the stability of the availability of AC sources. In this article, a multi-inverter coordinated control strategy is proposed for controlling the load power flow by using three photovoltaic (PV) arrays and each connected to a single-phase inverter. Coordinated control uses a Fuzzy Logic Controller (FLC) with three inputs and one output. Each input and output uses five membership functions. The FLC input is inverter A, inverter B, and inverter C, while the output is AC bus. The results of the study with coordinated control using FLC provide a stable output frequency of 50 Hz, while the PI controller produces a change in output frequency from 0.05 seconds to 0.35 seconds. Therefore, the AC load needs to be supplied quickly using FLC within 0.01 seconds, while the PI controller supplies power to the load within 0.15 seconds.
