The SPIN system can be employed to control the net power flow for residence based on its capability to forecast the PV generation and load. Residences with SPIN are capable of accumulating more PV energy in addition to maximizing their financial benefits under time-of-use electricity rates. This SPIN system can also enable the house to operate off-grid and improve home resilience during blackouts. This study evaluates the home resilience for a
typical house in California, where more residences are exposed to the risk of losing electricity abruptly. Factors including the time when the blackout occurs, ratings of RESS and PV, residential load, and the scheduling of the EV were all analyzed in this study.
Simulation results show that SPIN could coordinate the PV generator and energy storage operations, thus prolonging the self-sustain hours for a typical residence. The SPIN’s electronic interface is capable of incorporating the EV battery into the residential energy storage system, to further improve the home resilience significantly. This study also investigates the reduction of carbon emission and financial gain in long term in relation to SPIN system adoption. Houses equipped with SPIN could in theory operate as a distributed energy resource and provide grid ancillary services to the utilities.
