A Charging Coordination Strategy for Seamless Integration of Plug-In Electric Vehicles into a Distribution Network

Abstract

The tremendous rise in plug-in electric vehicles (PEV) has led to substantial transformations in the electricity and transportation industries. Uncoordinated PEV charging may result in power loss and overloading of distribution lines, which can be costly. An approach for coordinated charging is presented in this work that considers both grid-to-vehicle (G2V) and vehicle-to-grid (V2G) modes of action for PEV inclusion into a distribution network. To further understand the technological and financial implications of PEV uptake, a charging approach is developed to minimize charging costs. The proposed technique is tested in the IEEE 33-bus radial distribution system with parking lots located in the industrial nodes. The parking lots can be fed by either the grid or renewable energy sources. An empirical study is undertaken to identify the highest PEV penetration the grid can handle. To ensure that distribution lines aren't overloaded with PEVs, a feasibility study is done with and without a solar and wind-powered parking lot.
