摘　　要：扩展黑启动恢复策略对于加快大停电后的恢复过程具有重要意义,针对扩展黑启动方案的恢复效果研究,提出了一种基于综合权重的灰色关联评估方法。首先构建了一套较完整的评估指标体系,包括机组恢复、网络结构、运行状态等方面;其次采用模糊赋权法和熵权法分别计算各指标的主、客观权重,通过基于博弈论的组合赋权法优化得到指标的综合权重,克服了单一赋权法的不足;然后以改进的灰色关联分析法对扩展黑启动方案的恢复效果进行综合评估。10机39节点系统的算例结果验证了所提评估方法的有效性与合理性。A synthetic weight based gray correlation evaluation method to assess the recovery effect of extended black-start plan is proposed. Firstly, a relatively complete assessment index system including unit restoration, network structure, power flow distribution and operating states is constructed; secondly, the fuzzy weighting method and the entropy weight method are used to calculate the subjective and objective weights of the indices respectively, and the synthetic weight of each index is obtained by game theory based combination weighting method to remedy the defect of single weighting method; finally, the improved gray correlation analysis method is used to synthetically assess the restoration effect of the extended black-start scheme. The effectiveness and reasonableness of the proposed method are validated by simulation results of New England 10-machine 30-bus system;
