摘要:
主动配电网中分布式电源优化配置时,风光机组出力与负荷时序波动特性使场景过多,这既会增加模型求解的难度,也会影响优化配置结果。为此,首先引入戴维森堡丁指数(Davies-Bouldin index,DBI)结合K-means算法对全小时场景进行聚类缩减。然后,建立考虑风光与负荷时序特性的主动配电网双层优化配置模型,上层以系统年综合经济成本最优为目标,决策变量为风光机组接入配电网的位置及容量;下层以系统各时段运行电压水平最优为目标,决策变量为配电网主动管理措施下的运行成本;综合考虑风光机组时序出力和负荷侧时序响应,实现主动配电网分布式电源优化规划。最后,采用改进的自适应遗传算法对模型进行求解。IEEE 33节点系统算例表明,所提方法及模型在确保场景选取的多样性和合理性的同时,兼顾了风光机组出力与负荷时序波动特性,提高了系统运行水平,降低了系统运行成本。
