Electric Vehicle Smart Charging in a Single Residence with Rooftop Solar and Energy Storage

We pose and solve a two-stage smart charging (SC) problem for a single residence equipped with an electric vehicle (EV), battery energy storage system (BESS), and solar photovoltaic panels. We study the differences between an example rule-based operation of BESS and our SC problem, seeking to minimize homeowner costs and perform peak-shaving. Furthermore, we compare unregulated EV charging and our two-stage SC algorithm. We apply our models to a single residence in the Southern US with historical home demand and solar generation data under a time-of-use (TOU) rate plan to study cost changes alongside aggregate demand for one year. We determined our two-stage SC solution to be more effective at minimizing electricity costs and demand spikes under a TOU rate plan when compared to the rule-based operation of BESS and unregulated EV charging.
