摘要

分布式发电在为配电系统提供支持的同时,也带来了电源、负荷和线路的不平衡。传统的潮流算法不适用于带有dg的弱网格配电系统。首先,本文提出了一种基于BIBC矩阵和BCBV矩阵的直接算法。经过改进,适用于不平衡弱网格系统。然后采用灵敏度补偿的方法,对该三相潮流算法进行改进,使其能够处理由风力发电机组、光伏发电系统、燃料电池、蓄电池、微型涡轮机等组成的分布式配电系统。该算法在33节点系统中得到了验证。

Unbalanced Load Flow for Weakly Meshed Distribution Systems with Distributed Generation
Distributed Generation (DG) can bring support to distribution system, meanwhile, it bring unbalancedness in power source, load and line. Traditional load flow algorithms are not applicable to the weakly meshed distribution system with DGs. First, this paper present a direct algorithm based on BIBC matrix and BCBV matrix. With some improvement it is applicable to unbalanced and weakly meshed system. Then with sensitivity compensation method, this paper improve this three phase power flow algorithm, make it can deal with distribution system with DGs of wind turbines, photovoltaic system, fuel cells, storage battery, microturbines, etc.. This algorithm is proved in 33 nodes system.
