摘　　要：文章提出了一种无功优化资产配置模型,综合考虑投资无功补偿装置的费用和效益之间的平衡,将电压目标、网损目标和投资目标全部转化为费用进行优化。针对现有优化方法中负荷模型的缺点,提出全节点负荷断面聚类方法,将仅能处理实向量的欧氏距离推广到复数域的酉空间,给出全节点负荷复向量相似性度量方法及其K-means聚类的详细步骤。基于PG&E69节点系统的算例验证了所提模型的有效性。A reactive power optimal asset allocation model is proposed, which considers the balance be tween the cost and benefit of the reactive power compensation device. The voltage target, the net loss target and the investment target are all converted into the cost in optimization. Aiming at the short- comings of the load model in the existing optimization method, a method of the complete bus load sec- tion clustering is put forward. In this method,the Euclidean distance based on real vector is extended to the unitary space of the complex field. The method to measure the similarity between the complete bus load vectors and a detailed procedure for the complete bus load complex vector K-means clustering are given. The validity of the proposed model is verified by a numerical example based on the PG＆E69 system.
