基于双向出行链的电动汽车平抑电网波动策略

针对电动汽车(electric vehicle,EV)时空转移随机性造成的电网波动问题，计及车主的性别差异、车主实时出行目的地不同和车辆双向行驶，提出了一种基于出行随机性双向出行链的EV充放电调度策略。考虑车主实际出行过程,建立EV双向出行链模型；考虑到男女车主出行过程中的性别差异，确定男女实时出行概率模型；以降低电网的波动为目标函数，考虑车主实时出行需求和EV实时荷电状态(state of change,SOC)建立调度模型，并依据所建立模型对EV进行充放电调度。在约280 m²的区域进行仿真分析，结果表明：双向出行链模型更接近用户实际出行规律，其调度策略能够在满足用户实际出行需求的同时，更好地抑制电网波动性。

Stabilizing power fluctuation strategy based on two-way travel chain of electric vehicle

Aiming at the power fluctuation problem for the randomness of the time-space transfer of electric vehicles (EV),taking into account the gender difference of car owners,different real-time travel purpose and two-way travel of car owners,the charge-discharge dispatch strategy based on the two-way travel chain for the travel randomness of EV is proposed. Firstly,the two-way travel chain of EV is established by considering the actual travel process of car owners. Secondly, the real-time travel probability model is given by considering the gender differences of the male and female owners travel. Then,the dispatch model is set up by reducing the power fluctuation as the objective function according to the real-time travel demand of the owner and the real-time state of charge (SOC) of EV. Finally,the charge and discharge of EV are dispatched according to the established model,and the simulation if given by analyzing the cars in a area of 280 square meters. The simulation results show that the two-way travel model is closer to the actual travel law of owners,and the dispatch strategy based on the dispatched model of the two-way travel chain can better restrain the power fluctuation.
