Smart Control Strategies in Photovoltaic Systems: A Critical Review on Fuzzy Logic MPPT And PI Control For Charge Management

Photovoltaic (PV) system has attracted a tremendous attention of researchers as a sustainable and renewable energy source. Due to varying conditions such as temperature and irradiance, the voltage and current of PV panel also vary and thus the PV systems efficiency becomes very low. To enhance the efficiency, an advance algorithm Fuzzy Logic Maximum Power Point Tracking (MPPT) method is used. The fuzzy logic MPPT technique has emerged as a promising solution due to their simple design, best accuracy, adaptability and robustness in various operating conditions. The reviewing goal of this paper is to increase the efficiency and reduce the charging time as well as provide pertinent current and voltage for charging the battery. This paper presents the comparative study of various components and parameters for the optimization of Fuzzy Logic MPPT methods applied in PV systems, particularly in combination with Proportional-Integral (PI) control for charge regulation.
