考虑节点类型的节点优化方法改进

在潮流计算的节点优化方法中,传统的节点优化方法并未考虑各类型节点在形成修正方程时的不同作用。在分析PQ节点、平衡节点和PV节点在形成修正方程过程中作用的基础上,提出在半动态节点优化过程中针对各类型节点的特点进行区别处理的改进方法,经对算例进行节点编号优化试验,证明本方法可增强节点优化效果,并且不增加节点优化的工作量,进而加快潮流计算的速度。

Improvement of Node Optimizing with Node Type Considered

This paper, first of all, presents methods of node optimizing in the power flow calculation, and then it finds that the traditional method fails to consider effects of the different types of nodes type in the process of forming the modified equation. Based on the analyses on the effects of PQ node, slack node and PV node in forming the modified equation, the paper proposes a modified methodology, by which different methods are used to deal with different types of nodes in the process of the half-dynamic optimizing code. The optimizing experiment based on a practical example using the coding nodes in the paper proves that this method can accelerate the power flow calculation by improving the optimized effects without increasing the node optimizing workload.
