Direct Current (DC) microgrids are increasingly vital for integrating solar Photovoltaic (PV) systems into off-grid residential energy networks. This paper proposes a design methodology for standalone solar PV DC microgrids, focusing on Battery Energy Storage System (BESS) optimization and adaptive power management.
The integration and control of Microgrid (MG) systems remain critical challenges in the widespread adoption of renewable energy sources, especially photovoltaic (PV). An adaptive control approach is proposed in this work to improve the MG stability in the presence of PV and battery energy storage systems (BESSs).
The power of photovoltaic (PV) and electric vehicles (EV) charging in integrated standalone DC microgrids is uncertain. If no suitable control strategy is adopted, the power variation will significantly fluctuate in DC bus voltage and reduce the system's stability.
Overall, the results demonstrate that the designed standalone PV DC microgrid effectively stabilizes the DC bus voltage, optimally manages battery charging and discharging, and ensures reliable energy supply for residential loads under varying environmental and demand conditions. 6.
