摘要/Abstract

摘要： 提出一种适用于基于复杂网络理论的多直流馈入受端电网多目标优化分区方法。利用复杂网络理论分析电网的复杂网络特性和物理特性本质,构建加权模块度指标和平均输电距离指标,以评价网络分区质量和电网输电效率。考虑电网分区对多直流馈入系统的影响,采用加权多馈入短路比(multi-feed short-circuit ratio, MISCR)量化受端电网强度,建立电网分区方案评价指标集合。以最大化加权模块度和MISCR、最小化平均输电距离为目标,构建三目标优化模型,通过工程经验削减分区方案可行域,并基于NSGA-Ⅱ算法进行求解。以某省级电网为例,对比分析了所提方法的有效性。算例分析结果表明,所提方法具有更好的综合分区效果,更适用于多直流馈入受端电网。
