摘要
首先分析了配电网结构特点及DG节点类型,鉴于传统前推回代法不能直接处理弱环网和PV节点,对前推回代法进行改进,提出PV、PI、P-Q(V)、PI节点的处理方法,DG节点归类为PQ、PV、P-Q(V)、PI节点等,本文在传统前推回代法的基础上,对DG的节点进行特殊处理,并且利用迭代、叠加原理等手段得到改进前推回代法,并用标准算例验证了本文算法的可行性。
Firstly, the structural characteristics of distribution network and DG node types were analyzed, in the view of the fact that the traditional forward/backward sweep method can not deal with the weakly looped system and the PV node directly, the forward/back-ward sweep method was improved, proposed the processing method of PV, PI, PQ （V）, PI nodes, the nodes were classified as DG PQ, PV, PQ （V）, Pl nodes, etc. , this article based on the traditional forward/backward sweep method, the nodes of the DG are processed in special way, and formed the improved forward/backward sweep method with the use of iterations, superposition principle, etc. , the result of standard example showed the feasibility of the algorithm.
