Hybrid Controller Design for the Power Management of PV-SC HRES

Abstract

Energy consumption is required for human progress, and the twenty-first century is obligated to demand clean energy. The fast increase in electricity consumption has put pressure on the energy sector, particularly given the requirement to supply energy that is emissions-free today. Photovoltaic (PV) generator provides electrical power with zero carbon emission. PV delivers a DC power supply. The fluctuating load-current stress significantly impacts the efficiency and lifespan of the PV generator. In this study, a hybrid control system based on PI is presented to regulate the current limit and maintain the voltage level concurrently for hybrid systems supported by PV-SC under fluctuating load demand. The effectiveness of the suggested control strategy is first tested under varied loads in a MATLAB simulation before being put into practice at the Hardware-in-Loop OPAL RT platform. © 2023 IEEE.
