英文摘要:

      The orderly energy management of distributed new energy and electric vehicle（EV）in distribution network is studied.The probability distribution of distributed wind and solar are analyzed, and the wind and solar equivalent load model is established by probabilistic method. The electric vehicle load modely based on random travel simulation is analyzed, and the method of establishing the travel feature quantity is refined and improved. The three layer energy management model of the EV is constructed, the duties and division of the network side dispatching center and the charging service provider are clarified, the energy management strategy of tight coupling and loose coupling is proposed. The simulation results show that the energy management model proposed could effectively promote new energy consumption and load stagnation, realize new energy consumption/load stagnation on the distribution network, and the guidance and self?regulation of EV in the area under the jurisdiction of the demand of the charging service provider could be accepted.
