摘要: |
为在日前时间尺度上解决有源配电网优化调度问题,实现网架结构与分布式电源(distributed generation,DG)出力的协调调度,采用改进模糊聚类分析对负荷-DG等值负荷曲线进行时段划分,根据DG出力优化值对分段结果进行动态调整;采用机会约束方法处理不可调度DG随机出力问题,采用二层规划模型处理网架结构与DG有功出力协调问题,建立日前协调调度模型. 实验结果表明:网络重构与可调度DG的出力调整相互影响. 调度DG出力能减少开关动作次数,延长开关设备的寿命;网络重构能增加DG的渗透率,提高能源利用效率,增强配电网消纳DG的能力. 所提出的方法能够有效应对负荷变化,在提高配电公司经济效益的基础上,实现配电网资产与DG资源的综合利用.

Abstract: |
In order to solve day-ahead optimization scheduling problem in active distribution network and achieve coordination scheduling of grid structure and active power outputs of distributed generations (DGs), load-DG equivalent load curve is divided by improved fuzzy clustering analysis, and the partition results are adjusted on the basis of DGs outputs dynamically; a bi-level programming model dispatching grid structure and DGs outputs coordinately are presented based on chance constrained programming. The experiment results show that network reconfiguration and the scheduling of DG active power output influence each other. The scheduling of DG output can reduce the switch action and prolong the life cycle of switches, and network reconfiguration can increase DGs penetration and enhance the ability of DGs absorption. The method of this paper can deal with the load variation effectively, and distribution network assets and DGs can be utilized comprehensively.
