城市电动公交车具有电池容量大、可移动等特性,但现有研究将其作为固定位置储能参与电网运行,未能充分挖掘其在不同站点间移动充放电的特性。文中研究城市电动公交车在非运行时段作为移动储能优化配电网运行效益的方法。首先,建立电动公交车在不同站点间移动的时-空网络模型;然后,以配电网运行效益最大为目标,考虑公交车电量约束以及配电网运行约束,构建电动公交车-充电站-配电网联合优化调度的混合整数二阶锥规划模型,采用惩罚交替方向算法提高优化问题的求解效率。算例结果表明,所构建的电动公交车充放电方式在满足自身充电需求的条件下,能够降低配电网运行成本,缓解弃新能源现象。
Urban electric buses have the characteristics of large battery capacity and mobility. However
existing studies take them as the fixed-position energy storage to participate in power grid operation and fail to fully explore their mobile charging and discharging characteristics between different stations. This paper studies the method for regarding the urban electric bus as mobile energy storage to optimize the operation benefit of the distribution network during the non-operation period. Firstly
the spatio-temporal network model of the electric bus moving between different stations is established. Then
to maximize the operation benefit of the distribution network
this paper establishes a mixed-integer second-order cone programming model for the coordinated optimal dispatching of the electric bus
charging station and distribution network
considering the constraints of bus electricity quantity and distribution network operation. The penalty alternating direction method (PADM) is adopted to improve the solving efficiency of the optimization problem. Example results show that the proposed charging and discharging mode of the electric bus can reduce the operation cost of the distribution network and alleviate the phenomenon of abandoning renewable energy while meeting its own charging demand.
