摘要:

在“双碳”政策推动下,配电网面临海量分布式可再生能源接入带来的挑战,高效潮流计算分析成为应对这些挑战的关键手段.然而,现有的前推回代潮流计算方法在处理大规模节点配电网时,需要花费大量时间获得计算顺序和电抗矩阵,从而制约了潮流计算效率的提升.为此,提出一种融合叶节点递归剪枝的前推回代潮流计算方法.该方法充分利用配电网的拓扑特性,通过对叶节点实施递归剪枝,实现大规模配电网计算顺序的快速确定,同时获得对应的电抗矩阵,从而有效地提升潮流计算效率.仿真结果表明:相较于传统的分层类与搜索排序类前推回代法,求解效率更高,尤其在大规模配电网中,计算效率提升效果更为明显.

Abstract:

With the promotion of the “dual carbon” goal, distribution networks are facing challenges posed by high penetration of distributed renewable energy. Efficient power flow analysis is thus essential for addressing these issues. However, existing back/forward power flow calculation methods are inefficient for large-scale networks, as determining the calculation sequence and constructing reactance matrix are extremely time-consuming. To solve this problem, a back/forward sweep power flow calculation method integrated with leaf nodes recursive pruning is proposed. By leveraging the topological characteristics of the distribution network, the method performs recursive pruning on leaf nodes to rapidly determine the calculation order for large-scale distribution networks with massive nodes. It also enables the efficient construction of the corresponding reactance matrix simultaneously, thereby effectively enhancing the efficiency of power flow calculations. Simulation results indicate that the proposed method outperforms existing layered and search-sorted back/forward power flow methods in terms of solution efficiency. The improvement is particularly pronounced for large-scale distribution networks, where the advantages are more evident.
