The mathematical model of the photovoltaic (PV) system is developed and simulated. The maximum level of power point tracking is implemented for operating the PV system at optimal power generation using an intelligent controller with analysis of the system performance. A multi-port converter design is proposed and simulated. The proposed converter is controlled by Fuzzy-logic controller for effective utilization of PV power generation and battery management system. The proposed Fuzzy logic based controller is designed for PV and battery management system at various load demand and weather conditions. The proposed system performance is analyzed at the different weather and load demand. The simulated results show the effectiveness of the proposed system. © 2024 Elsevier B.V., All rights reserved.
