The proposed control method is formed from constant current (CC) and constant voltage (CV) controllers with a fault detection method. In normal operating conditions, the proposed controller operates in CC control mode to control the power flow between the battery and the dc grid. The fault detection method observes grid voltage in real-time to detect grid voltage disturbance on the grid. If a voltage disturbance is detected, the fault detection method switches the controller to CV mode to maintain a stable bus voltage on the dc microgrid. Performance evaluations conducted via Matlab/Simulink demonstrate the effectiveness of the proposed method in stabilizing load voltage, managing battery charging/discharging efficiently, and enhancing system reliability without additional control complexities. This approach provides a significant advancement toward stable, efficient, and resilient DC microgrid operations.}, number={3}, publisher={MUSA YILMAZ}
