The use of electric vehicles (EVs) for household uninterruptible power supplies (UPSs), particularly in rural areas, can greatly improve household power reliability. However, because EVs are mobile, the evaluation of backup capacity for EV-UPS systems is completely different when compared to traditional UPSs. As a result, the focus of this
A micro-grid system which is connected to the large grid is composed of distributed power sources (WP, PV), ESS, and EVCS. Due to the typical intermittent and random nature of distributed wind and solar power, and the fluctuation and uncertainty of charging demand, it is easy to cause uneven supply and demand resulting in large load
