Improving the Power Outage Resilience of Buildings with Solar PV through the Use of Battery Systems and EV Energy Storage

Buildings with solar photovoltaic (PV) generation and a stationary battery energy storage system (BESS) may self-sustain an uninterrupted full-level electricity supply during power outages. The duration of off-grid operation is dependent on the time fault capabilities home management (HEMS). In this paper, building resilience quantified by analyzing self-sustainment for all possible outages throughout entire year. An evaluation method proposed exercised reference house in California climate zone 9 which detailed usage simulated using EnergyPlus software. influence factors such as use behavioral patterns, capacity from BESS, electric vehicle (EV) evaluated. Varying combinations controllable loads are studied optimally improved based user preferences. It shown that target region PV 7.2 kW, BESS 11 kWh, EV 80 kWh permanently connected to home, self-sustained full guaranteed at least 72 h.
