摘　　要：构建了多层分布式潮流计算系统,研究了分布式潮流异步协调算法,并进行了两层和多层的异步迭代潮流计算。IEEE标准系统测试结果表明,通过选取合适的松弛因子,分布式潮流算法可获得较高收敛性,并能有效克服同步算法存在的同步等待问题,适用于在广域网络环境潮流计算。In this paper the authors construct a multi-layer distributed computation architecture, research an asynchronous coordinative schedule algorithm to deal with distributed power flow calculations of vertically integrated power systems and implement the asynchronous iterative power flow calculation of two layer and multi-layer. The test results by IEEE standard test system show that by means of choosing proper relaxation factor, a better convergence of distributed power flow calculation can be achieved, and the synchronous waiting problem can be effectively overcome. The proposed algorithm is suitable to the environment of wide area network.
