摘要 在构造电力系统分解协调模型的基础上,采用辅助问题原理进行分布式并行最优潮流运算,并用通用增广拉格朗日法加快收敛速度,对分布式并行优化算法做了详细推导.仿真结果表明,该算法可显著加快大系统的优化速度,提高控制的实时性和可靠性,符合电力市场发展的需求. Based on the decomposition-coordination model of an electric power system, auxiliary problem principle and the general augmented Lagrangian method are adopted for the distributed and parallel optimal power flow solution by decomposing the system network into independent subsystems in different areas. Test results show that the algorithm can speed up the optimization process, reduce the cost of communication and improve the stability of the system. The application of this algorithm is applicable to power market development.
