Description
Summary:	The utilization of renewable energy resources (RESs) has gained significant popularity due to their numerous advantages. The primary objective of this research is to design a distributed, highly efficient standalone 72V solar photovoltaic (SPV) direct current (DC) microgrid that is specifically designed for electric vehicle (EV) charging and rural illumination purposes. A standalone DC microgrid (MG) integrates SPV with an advanced energy management system (EMS) and a battery energy storage system (BESS) controller. The integration of DC-DC converters provides the efficient integration of a BESS with SPV. The design incorporates a DC MG with self-generation capabilities, storage facilities, and bidirectional power flow capability, giving a comprehensive solution for sustainable energy consumption in the environment of EV charging and rural lighting. The SPV system, along with BESS, acts as a reliable power source, ensuring uninterrupted power supply during outages. The EVs are interconnected with a DC bus and bidirectional DC-DC converter enable efficient power sharing. The EMS optimizes load scheduling and decision-making, particularly an emphasize on sustainability and addressing rural consumption of energy. The proposed DC microgrid is successfully built and simulated with MATLAB Simulink to analyze its performance and management technique.
