A New Approach to Charging of Electric Vehicles

Abstract: This paper proposes a new control method for charging management of Electric Vehicles (EVs). The goals of the proposed control method are to reduce EV integration challenges, such as over-currents and under-voltages, and also improve the power factor. The proposed method controls the charging rates of the chargers in the distribution systems using cooperative control in order to prevent the network from under-voltages and overcurrents. The proposed algorithm is tested on the IEEE 33-Node Test Feeder and the simulation studies are carried out using OpenDSS and MATLAB. The pros and cons of the proposed method are presented and compared to the other EV charging methods.
