摘要
电力系统网络具有很强的稀疏性 ,基于分割理论而形成的对角块加边网络模型 (bordered block diagonal form—BBDF)在电力系统并行计算中应用广泛。本文研究了 BBDF的各种并行潮流算法 ,提出了一种异步并行算法——异步块牛顿迭代法 ,并在 PC机上以多线程模拟 。
Power system is a large scare network and its equations matrix possesses strong sparsity. Block Bordered Diagonal (BBD) model is widely used in parallel computation of power system. In this paper, after the analysis of various parallel load flow algorithms an asynchronous parallel algorithm, i.e., asynchronous block Newton iterative algorithm, is presented. This algorithm is implemented on PC with multi threads and shows satisfactory convergence.
