摘要

针对多区域互联系统的协调调度问题，提出了一种考虑跨区联络线交易计划的分散调度方法。首先，提出了跨区电力交易计划需要满足的约束条件，通过优化联络线通道电力曲线来促进互联电网的风电消纳，建立了全网集中式调度模型。然后，采用交替方向乘子算法对集中式调度模型进行重构，建立了一种完全分散式的调度模型。为了加快分散式模型的求解速度，提出一种启发式方法，通过固定机组状态变量，减少二进制变量的个数，简化了区域子问题的复杂度，并且加快了分散式算法的收敛过程。最后，将该方法应用于两个算例系统开展算例分析，计算结果验证了该方法的有效性。

Abstract

A decentralized dispatch method considering the cross-area tie-line trading scheme is proposed to address the coordinated dispatching of multi-area interconnected power systems. Firstly

the constraints of cross-area electricity transaction strategies are considered and the centralized dispatch is modeled with the optimization of electricity trade curve via the tie-line transmission channel to improve the wind power accommodation. Then

the fully decentralized dispatch is modeled by reconstructing the centralized model using the alternating direction method of multipliers. To speed the computation

a heuristic method is developed by fixing binary variables. The heuristic method simplifies the complexity of area sub-problem and accelerates the convergence of the decentralized algorithm. Finally

the applicability of the proposed method is addressed on two test systems. The calculation results verify the effectiveness of the proposed method.
