Abstract
The increasing use of renewable energy sources necessitates advanced energy management in DC microgrid systems for their stability, efficiency, and reliability. This paper presents a design and simulation of a DC microgrid incorporating renewable energy sources and energy storage. The system integrates a 10.5 kW PV array and 0.65 kW battery energy storage system, managed by bidirectional and boost converters. The goal is to demonstrate the effective use of the DC bus for balancing generation and load demands while optimizing energy flows within the microgrid. The simulation results show the system's capacity to handle variable renewable generation and load profiles, ensuring a constant and uninterrupted power supply. Strategic control of power electronic converters is crucial for maintaining DC bus voltage within desired thresholds. This study contributes to sustainable energy solutions by showcasing the potential of integrated renewable resources in a DC microgrid.
