摘要

提出了考虑区域间传输断面交易功率约束的互联电网联网最优潮流模型及其算法。该模型中，以网损最小为目标函数，其约束条件中包含了系统的潮流约束、传输断面的有功功率约束以及系统各个变量的运行约束，由此不但可以满足区域断面之间的交易功率约束，而且能保证互联电网的优化运行。针对目前互联电网分层分区管理的特点，根据此最优潮流模型，采用母线撕裂法对互联电网进行切分，建立了相应的分解协调模型，并采用分解协调内点法求解，以进一步提高模型的求解效率。通过对4个测试算例的仿真分析，证明了文中所述模型及其算法的正确性及有效性。

Abstract

A model and algorithm of interconnection optimal power flow（OPF），which considers the trade power constraints of transmission interface，is provided for interconnected power grid. The objective of the OPF model is to minimize the active power loss to guarantee the optimal operation of interconnected power grid. The active power constraints of transmission interfaces between each regional power grid are considered to satisfy the trade power constraints of the interfaces. The operation feasibility constraints of each variable are included in the proposed model. Considering the interconnected power grid is formed by multi-area power grids，the border bus is copied and the interconnected power grid is divided. A decomposition-coordination OPF model is established based on the proposed interconnection OPF model. The decomposition-coordination interior point method is used to solve the decomposition-coordination OPF model. The decomposition-coordination OPF model and decomposition-coordination interior point method can improve the computational efficiency. The simulations for the four test systems demonstrate the correctness and effectiveness of the proposed optimal power flow model and algorithm.
