PERFORMANCE INVESTIGATION OF A MICROGRID SYSTEM WITH BIDIRECTIONAL DC-DC CONVERTER CONTROL FOR RENEWABLE ENERGY INTEGRATION

Abstract

The focus of this project is on the performance of a microgrid system incorporating renewable energy sources (photovoltaic (PV) and wind turbines), battery storage, and a bidirectional DC-DC converter. The objective is to assess the efficiency and stability of energy flow management and continuous power supply to the load from the point of view of varying conditions. Finally, MATLAB/Simulink simulations were performed on both steady state and dynamic (fluctuating PV generation, wind speed and load demand) conditions. Results show that energy storage must be controlled optimally to minimize AC grid dependence and maintain state of charge (SOC) of battery within reasonable levels. The microgrid system was analyzed and key performance metrics such as voltage regulation, current distribution, power flow optimization, and integrating renewable energy sources were effectively optimized. Balance between the battery and the DC bus is primarily carried out by the bidirectional DC-DC converter. The balance of study concludes that microgrid systems, operating with efficient energy management, are able to deliver a sustainable and resilient power answer for modern energy needs. Usage of the battery management system will be future work, investigating hardware.
