摘　　要：电动汽车(electric vehicle,EV)与储能装置在电力系统中的渗透率不断提高,能够作为可调节资源参与配电网的优化调度。首先在潮流模型、储能运行模型、EV集群充电站模型的基础上建立了配电网经济调度模型,以网损最小化、储能与充电站充电成本最小化作为日前调度目标;其次,基于交替方向乘子算法(alternating direction method of multipliers,ADMM)设计了适用于该优化模型的主从结构分布式求解方案,以充分发挥配电网内资源的自主协调能力;最后基于33节点算例进行仿真,仿真表明了储能与充电站参与配电网调度对于储能运营商与配电网是双向收益的,且基于ADMM的分布式求解方案具有有效性。The penetration rates of electric vehicles and energy storage in the power system are increasing, and they can participate in the optimal dispatch of the distribution network as the deployable resources. Firstly, based on the power flow model, energy storage operation model and EV cluster charging station model, the economic dispatching model of distribution network is established.The goal of day-ahead dispatching is to minimize the network loss and the charging cost of energy storage and charging station. Secondly, a leader-followers distributed solution was designed based on ADMM to give full play to the autonomous coordination of resources in the distribution network. Finally, based on a 33-node example, the simulation results show that the energy storage and charging stations participating in the distribution network dispatching is a two-way benefit for the energy storage operator and distribution network, and the distributed solution based on ADMM is effective.
