摘　　要：为提升新型电力系统的非常规安全防御能力,提出了计及新能源场站黑启动时空支撑能力的分区目标网架优化方法。首先,基于新能源场站黑启动时空支撑能力定义了扩展黑启动电源;其次,以最小化分区内电气距离之和和分区间联络线数目为优化目标,将扩展黑启动电源转化为分区数量约束,并同时计及功率平衡、分区连通性、灵活性资源等约束,建立了计及扩展黑启动电源的分区目标网架整数线性规划模型;最后通过仿真系统验证了所提方法有助于新能源场站黑启动分区恢复决策。Taking into account the spatiotemporal support capacity of new energy station black start,a target network optimization method for power system black-start zoning is proposed to improve unconventional security defense ability of the new power system.Firstly,extended black-start power source(EBSPS)is defined based on the concept of spatiotemporal support capability for black start of new energy stations.Secondly,with the optimization objectives of minimizing electrical distance within the partition and the number of interconnections between partitions,an integer linear programming model for partition target network that takes into account EBSPS is established,in which EBSPS is transformed into a constraint on the number of partitions and other constraints such as power balance,partition connectivity,and flexibility resources are considered as well.Finally,the proposed method was validated through a simulation system to aid in the decision-making process for restoring black start zones in new energy stations.
