摘要

为提高分布式光伏的消纳率,提出基于集群划分的配电网分布式资源鲁棒联合规划方法。首先,提出包含模块度指标、有功无功平衡度指标、源荷同时率指标的综合集群划分指标,并利用改进的遗传算法求解得到集群划分结果。其次,在集群划分的基础上提出配电网分布式资源鲁棒联合规划模型,上层考虑集群内源、荷的不确定性,建立分布式资源鲁棒选址定容模型,通过不确定性调节参数确定源-荷不确定性集的范围,得到分布式光伏以及储能的最佳接入位置和容量;基于上层得到的选址定容结果,下层建立考虑可靠性指标计算的配电网运行模型,通过考虑集群孤岛运行概率的可靠性指标表达式计算方法,求解出可靠性指标结果与运行信息传递给上层;多轮迭代优化确保最终方案在鲁棒性和可靠性之间的平衡。最后进行仿真分析,验证了所提方法的有效性。

Abstract

In order to solve the problem of location and capacity determination and reliability index calculation of distributed resources in distribution network with high proportion of distributed generators, a robust joint planning method of distributed resources in distribution network based on cluster division is proposed. Firstly, a comprehensive cluster division index of distribution network was proposed, which included modularity index, power balance index and inter-group branch power fluctuation index. Secondly, on the basis of cluster division, a two-layer joint programming model is proposed, and the upper layer considers the uncertainty of the source and load in the cluster, establishes a source-storage robust addressing and capacity model, and determines the range of the source-load uncertainty set through the uncertainty adjustment parameters, so as to obtain the optimal access location and capacity of distributed power generation and energy storage. The lower layer considers the calculation of reliability indicators in the cluster to ensure the reliability of operation and reduce the conservatism of optimization results. Finally, the simulation analysis of the actual photovoltaic distribution network in China is carried out to verify the effectiveness of the proposed method.
