大规模电网并行潮流算法

提出了一种大规模电力系统并行潮流算法。该算法将电力网络划分成若干个子网，以子网为计算节点、联络线为支路构造浓缩网格，进行潮流计算时通过双向迭代方法交替实现对网格和网格中计算节点的牛顿法线性增量方程的求解。该算法有效提高了电力系统潮流方程联立求解的效率，为大规模电力系统并行潮流计算提供了方法。在新英格兰测试系统和我国东北电网上进行了验算，结果验证了算法的有效性和合理性。

New Research on Parallel Power-Flow Calculation for Large-Scale Power System

A new parallel algorithm of power flows in large-scale power grid is proposed. In this approach at first the whole power network is divided into several subnets connected by tie-lines; then a concentrated grid can be constructed with the subsets as computing nodes and the tie-lines as branches; and then by means of bi-directional iteration the linearization incremental equations of computational grid and its computing nodes are solved. The proposed algorithm improve the efficiency of simultaneous solution of power flow equations effectively and offer a new approach for parallel computation of power flows in large scale power grid. By use of Matpower software, checking computations of the proposed algorithm are performed with New England test system and Northeast China Power Grid. Power flow calculation results show that the proposed algorithm is effective and reasonable.
