高斯-快速解耦潮流算法

高斯法潮流计算中，PV节点转化为PQ节点易造成计算收敛缓慢，对此文中提出了应用快速解耦法处理网络中PV节点的方法。该方法应用传统高斯法处理PQ节点，利用高斯消元法消去网络中的PQ部分，得到了一个由PV节点和平衡节点组成的网络，然后用快速解耦法求解这个网络，从而实现了算法的快速收敛。该方法有恒定的雅可比矩阵、且内存占用量小、收敛可靠、计算速度快。

A Load Flow Algorithm Based on Gauss Algorithm and Fast Decoupling Algorithm

In load flow calculation by traditional Gaussian algorithm, the convergence of the computation frequently becomes slower when the PV nodes are transformed into PQ nodes. For this reason, an approach using fast decoupling method to process PV nodes is proposed. In the proposed approach, traditional Gaussian algorithm is used to process PQ nodes and the PQ part of the network is eliminated by Gaussian elimination method, thus a network consisting of PV nodes and a balance bus is obtained, and then the obtained network is solved by fast decoupling method to implement fast convergence of the algorithm. The features of the proposed approach are as following: constant Jacobian matrix, less memory occupation, reliable convergence and high computing speed.
