Abstract

This paper presents a new modeling framework for inclusion of the charging operations of Plug-in Electric Vehicles (PEVs) within a three-phase unbalanced, residential, distribution system. Coordinated charging of the PEVs is proposed to minimize the total energy drawn from the substation, total losses in the system and the total cost of charging the PEVs. Detailed studies examine the impact of PEVs on the overall system load profile, bus load profiles, feeder currents, voltages, taps and capacitor switching. The proposed model can be used to maximize PEV charging over a 24 hour time-frame or the utilization of feeder capacity to charge the PEVs. A practical distribution test feeder is presented to demonstrate the features of the proposed model.
