摘　　要：针对现有配电网负荷三相不平衡优化算法计算效率不高且难以适应负荷波动场景这一现状,提出了一种基于序优化的配电网负荷三相不平衡优化策略。首先建立粗糙模型,筛选单相负荷接入相序的初始解集;然后建立精确模型,考虑三相负荷约束,对初始解集再次筛选优化;最后通过实际算例来验证所提方法的有效性。分析表明所提方法保证了求解精度的同时,提升了3~5倍的求解效率。The calculation efficiency of the three-phase unbalance optimization algorithm for the existing distribution network load is not high and it is difficult to adapt to the load fluctuation scenario.The paper proposes a three-phase unbalance optimization strategy for the distribution network load based on ordinal optimization(OO)algorithm.Firstly,a rough model is established to screen the initial solution set of single-phase load access phase sequence.Then a precise model is established,and the initial solution set is filtered and optimized again considering the three-phase load constraint.Finally,actual examples are used to verify the effectiveness of the proposed method.The analysis shows that the proposed method ensures the solution accuracy and improves the solution efficiency by 3~5 times.
