摘要/Abstract

摘要： 制定合理的电网并行恢复分区方案可以有效缩短系统恢复时间，而如何构建更为有效的分区模型及算法是该问题的关键。提出了电网并行恢复的分区新模型及快速求解算法。首先根据系统恢复的实际过程，构建了完善的系统并行恢复最优分区新模型；进而，为了克服大型混合整数非线性规划问题求解的困难，提出了分步求解策略：先基于电气距离对待启动机组进行划分和调整；再基于电气距离和潮流追踪算法的负荷分区和调整。所构建的模型相对比较完整，所提算法计算性能好且易于实现，而有望用于工程实际。不同规模算例验证了所提模型及算法的有效性和正确性。

Abstract: Establishing a reasonable grid partition scheme for parallel restoration can effectively shorten the system restoration time, while how to build a more effective partition model and algorithm is the key to this issue. This paper proposes a new partition model and fast algorithm for parallel restoration of power grids. Firstly, based on the actual process of system restoration, a new model is constructed for optimal partitioning of system parallel restoration; And then, in order to overcome the difficulty for solving the large mixed integer nonlinear programming, a step-by-step solution strategy is proposed: First, the start-up units are divided and adjusted according to the electrical distance; Second, the loads are divided and adjusted based on electrical distance and power flow tracking algorithms. The model constructed in this paper is relatively complete, and the proposed algorithm has good computing performance and is easy to implement, which is expected to be used in engineering practice. Examples of different scales have verified the effectiveness and correctness of the model and algorithm proposed.
