In order to improve the participation ratio of electric vehicle users in orderly charging

reduce the charging load ofelectric vehicles in the peak period

and delay the overload of distribution transformers

the medium charging management mode and longterm charging management mode are setted. According to the user’s willingness to charge

time of use electricity price period

and the residence time of electric vehicles in residential areas

which can meet different charging needs in orderly charging.Among them

the charging start time of the medium charging man agement mode is selected by the reverse order method to achieve the peak cutting and peak shifting effect

according to the residen tial load change characteristics

and the long term charging manage ment mode uses the maximum minimum load value method to select the charging start time to achieve the effect of filling the valley.The proposed strategy provides users with more choices and the simulation results show that the load peak and off peak difference

the load variance

and the charging cost can be further reduced

through coordinating the user participation ratio of different man agement modes.
