In order to meet the practical value of electric vehicle dispatch, from user profile, this paper adequately takes the electric vehicle users’ driving demand into consideration, defines the users’ satisfaction as the combination between charging-discharging cost and reasonability, and puts forward the electric vehicle optimus charging-discharging tactics in terms of the users’ satisfaction maximization, with combination of the battery cost. On this basis, this paper discusses the different users’ satisfaction pattern under different weight combinations. Through particle swarm optimization, the simulation result in Matlab can verify that users’ satisfaction maximization can be realized by the tactics put forward in this paper, meanwhile, the tactics under all of the patterns will not arouse serious effects on the existing urban electric distribution network.
