Abstract
In this study, we propose an autonomous DC microgrid system for residential community with distributed power exchange control to increase the utilization of renewable natural energy and to ensure minimal energy supply in the event of a large-scale disaster. Assuming small community of 20 houses, each house in the microgrid has its own in-house system that can continue to provide power to appliances from its own batteries and solar panels even when disconnected from the utility grid or power outage. Using solar irradiation time series and individual household power demand records, we examined its performance using real-time simulations. Finally, we propose a sustainable power system based on renewable energy that further minimizes fossil fuel consumption by integrating a renewable auxiliary power supply system such as the hydrogen energy system.
