Abstract [en]

The integration of photovoltaic (PV) and EV charging into residential buildings has increased inrecent years. Within this context, researchers have developed advanced controls method for powerflow called B2V (Building to Vehicle). Furthermore, to improve the local balance between PVpower supply and EV demand, researchers have proposed another form of control method,B2V2B (Building to Vehicle and Vehicle to Building) in which the vehicle plays the role of a storagesystem as a battery that works as a bi-directional flow that can be charged and discharged. Thefrequent charging/discharging could potentially accelerate the EV battery degradation, whichmight make such applications not economical. However, systematic investigation has rarely beenconducted for the impact of various EV usage and charging factors (including the EV chargingstrategy, different EV charging forms, EV charging limits) on the power balancing performancesand EV battery cycling degradation. This study conducts an investigation into electric vehicle (EV)charging strategies (i.e., B2V and B2V2B) on demand response performances and EV batterydegradation. A parametric study considering a set of different scenarios combining various EVcharging forms and EV charging limits is conducted in the Swedish context. A smart chargingcontrol method of the EV will be developed, which can optimize the EV charging and dischargingrates to minimize the grid interactions. Then, both the calendar degradation and cyclingdegradation of the EV battery are investigated under different scenarios. The study results canhelp improve researchers’ understanding of the impacts of smart EV charging in the buildingcommunity performances.
