摘　　要：主动配电网(active distribution network,ADN)拥有更多的调度自主权,能够主动管理分布式发电机、储能设备以及主动负荷,实现配网的高效运行。主网与配网调度结果相互影响,因此在制定ADN优化调度方案时,除了考虑自身的运行成本,还应该兼顾与主网之间的协调问题。该文设计配网与主网实时信息交互模式,对主动负荷和储能设备进行建模分析,提出基于实时电价的协调调度模型;并针对该调度模型,提出并行优化算法,通过对连接配网的IEEE 9节点系统进行仿真,验证了模型及求解算法的有效性;最后,分析比较了需求侧响应、储能设备和联络线功率上限对调度结果产生的影响。Active distribution network（ ADN） with more autonomy in dispatching is able to control distributed generators,energy storage equipments and active load,which can realize the efficient operation of distribution network. The dispatching schedule of main network and distribution network influences each other. Besides the operating cost,the coordination of main network and distribution network should be considered when we make the optimal schedule of ADN.This paper provides a real-time information interaction mode,carries out modeling analysis on active load and energy storage equipments,and proposes a coordinative dispatching model based on real-time pricing. In addition,a parallel optimization algorithm is presented aiming at the scheduling model. Simulation results on the IEEE 9 node system connected with a distribution network verify the validity of the model and the algorithm. Finally,we analyze the influences of demand response,energy storage equipments and power limit in interconnecting lines on the dispatching schedule.
