Abstract

In this paper, a combined photovoltaic (PV) solar panels (PVSP) and Super capacitor (SC) renewable power generating unit feeding 3-phase, 380V/ 50 Hz loads is studied. The renewable power generation unit is operated as an off-grid setup. SC is used to maintain the required load power demand during lower power generation stages by PV system due to changes in environmental conditions. It is aimed to have clean power at stable frequency and voltage on the loads. The voltage on loads in the system is controlled by both Proportional-Integral (PI) and Fuzzy Tuned PI (FTPI). A comparison is made for the performance of these controllers to select the one that has better applicable properties. The complete setup contains PVSP, SC, filters, inverter, controllers, measurement devices and loads. All of the subsystem models are developed and combined using operational blocks of MATLAB/Simulink to obtain the overall system model.
