Islanding operation methods integrated with multiple power supplies and HEMS

This paper investigates the operation of various possible standalone power supply configurations for smart houses with a view to preventing inconvenience to residents when blackouts occur. In smart houses, various types of power-generation equipment (such as photovoltaic (PV), battery energy storage system (BESS), electric vehicle (EV), and fuel cell (FC) systems) with different output power, capacity, and response time characteristics are used. Our results indicate that combined use of these equipment and home energy management system (HEMS) control provide the best means of enabling residents to effectively use household appliances even in limited power supply situations.
