Research on optimal control of electric vehicle charging in residential area

This paper analyzes the driving characteristics of electric vehicles in the residential area in detail and proposes a charging control strategy based on optimal parameters, which makes the peak load constant and the peak-valley difference minimum in the load curve of residential distribution system after connecting large scale of electric vehicles. In order to increase utility, with the principle of peak load limited in pre-set range and peak-valley difference not increasing, a charging strategy based on optimal parameters and effective interval was proposed. Finally, the effectiveness of proposed control strategy is verified by calculation example based on a typical residential area and the traditional random charging and delayed charging are compared with the proposed control method.
