📄 Abstract（原文）
Residential microgrids are expected to enhance both environmental sustainability and disaster resilience in future housing developments. This study investigates two distributed control schemes for residential DC microgrids: an autonomous distributed cooperative control based on the state of charge (SoC) of battery-driven DC/DC converters, and an autonomous decentralized control based solely on feeder voltage, enabled by directly connected distributed batteries. A detailed DC microgrid model consisting of five houses was constructed in MATLAB/Simulink, incorporating PV panels with different orientations, small wind turbines, household load profiles, EV charging, and realistic meteorological data. The cooperative control scheme effectively stabilized feeder voltage, suppressed surplus renewable generation, and reduced reverse power flow to the utility grid. The decentralized scheme also maintained stable feeder voltage without device-to-device communication, although it resulted in greater reverse power flow due to less effective generation curtailment. In both schemes, houses near the grid-interconnection point experienced more frequent battery cycling, indicating the need for larger battery capacities at those locations. Simulations showed that installing approximately 20 kWh of battery capacity per house enables more than 80% of annual consumption can be obtained from renewable energy and allows continued operation during off-grid conditions with reduced consumption. These results demonstrate the practical feasibility of distributed-control residential microgrids.
