摘　　要：使用辅助问题原理(APP)和序列2次规划(SQP)的分布式最优潮流算法来解决跨区域的输电阻塞问题。研究大系统互联电网的最优潮流优化(OPF)策略,分析电网分区的分解协调模型,使用APP来解决区域耦合约束,将一个大的电网互联系统分解成多个区域子问题。跨区域阻塞管理问题可描述为调整成本最小的优化问题,通过区域分解把跨区域阻塞管理问题分解为多个区域的SQP问题,这些问题可在分布并行的方式下求解。对3个区域互联的IEEE RTS-96算例进行分析,结果表明该文算法是一种有效的跨区域输电阻塞消除算法,在电力市场中有良好的应用前景。Multi-regions transmission congestion is solved using auxiliary problem principle （APP） and sequential quadratic programming （SQP）. An optimal method of optimal power flow （OPF） in large-scale interconnected power grids is investigated. A decomposition collaborative model is analyzed and coupled constraints are solved based on APP. The computation of large power grid is decomposed into multi-regions subproblems. The distributed OPF algorithm is used to eliminate the congestion of across areas. The problem of congestion can be described as the optimal problem that the adjustment cost is minimal. Multi-regions congestion management problem can be decomposed into multi-regions subproblems, which can be solved as SQP. The IEEE RTS-96 with three interconnected regions is studied to illustrate the effect of the proposed approach and reveal that it has a bright future for the application in interconnected power system.
