A Mobile Energy Storage Unit Serving Multiple EV Charging Stations

Due to the rapid increase in electric vehicles (EVs) globally, new technologies have emerged recent years meet excess demand imposed on power systems by EV charging. Among these technologies, a mobile energy storage system (MESS), which is transportable that provides various utility services, was used this study support several charging stations, addition supplying grid during overload and on-peak hours. Thus, paper proposes day-ahead optimal operation of single MESS unit serves stations share same geographical area. The operational problem formulated as mixed-integer non-linear programming (MINLP), where objective minimize total operating cost parking lots (PLs). Two different case studies are simulated highlight effectiveness proposed compared current approach.
