Abstract

Abstract:

In view of the serious hidden danger to the power grid and long charging time caused by the random parking behaviors and disordered charging process of electric vehicles （EVs） in residential areas，an EV orderly charging control strategy with delayed charging is proposed.After analyzing the researches on EV orderly charging at home and abroad，the overall framework of an orderly charging strategy for EVs in urban communities is designed.The strategy can coordinate EV charging behaviors by delayed charging.It can ensure the state of charge （SoC） of the EV at departure time by setting its charging start time which is varies with the calculated charging priority，so as to meet users' demand for SoC to the greatest extent.The simulation analysis on a case show that the proposed strategy with delayed charging can achieve the effect of peak-load shifting on the premise of meeting users' expectations for EV charging results.

Key words: electric vehicle, orderly charging, delayed charging, peak-load shifting, renewable energy consumption, energy storage
