摘要
随着计算机和网络技术的发展,传统的某些计算方法已经不能满足电力系统实时在线评估的要求。在网格平台下,可以对已有的电力系统分析算法进行改进或研究新的能够满足分布式并行计算的算法。针对最基本的潮流计算问题,基于矩阵求逆的分块递推法和分解叠加法,研究其并行算法并应用到电力网格中以快速求解潮流问题。仿真结果说明这2种并行算法在网格平台下有很好的加速比,能有效地提高潮流计算速度。
With the development of computer and intemet technology, some traditional algorithmic method can not meet the requirement of the real-time online evaluation of the power system. In the platform of grid, the algorithm of power system analysis can be improved and new algorithms were researched to meet the new distributed parallel computing. Aimed at the most basic power flow calculation, based on the block recursive method and decomposition of superposition method of the matrix inversion, the parallel algorithms were studied and applied in Power Grid, which can solve the power flow problem fast. The simulation results indicate that these two parallel algorithms have a good acceleration ratio in the grid platform, and can improve the power flow calculation speed effectively.
