Photovoltaic emulator using error adjustment fuzzy logic proportional-integral controller

The photovoltaic (PV) technology has been increasingly used in our energy generation. Therefore, it is essential to have a good PV testing facility during the development process. emulator (PVE) voltage or current source that mimic current-voltage characteristic as module requires proper control strategy work. resistance feedback method (RFM) many attributes, except transient response, which caused by proportional-integral (PI) controller. This paper proposed new fuzzy logic PI (FLPI) controller improve performance of RFM PVE. It based on error adjustment founded state and load PVE compared with original finding research shows improved 2.3 times without affecting its accuracy.
