Abstract

This paper proposes a photovoltaic (PV) power scanning aided hybrid control for dc microgrids (dcMGs) with PV and battery energy storage systems (BESSs). In contrast to existing dcMG controls, the proposed control reduces the BESS utilization for dc-link voltage regulation, even under partial shading conditions. To achieve this, a power-voltage (P-V) curve scanning mechanism is integrated within a flexible power point tracking algorithm, bypassing local maximum power points and matching the PV power to the demand. Compared to conventional periodic and full P-V curve scanning approaches, the proposed scanning is event-triggered and its range is adaptive by terminating the scan when a PV power that satisfies the demand is identified. The proposed control effectiveness is verified through simulations in MATLAB/Simulink. © 2025 IEEE
