Abstract: In recent years, loads of many urban distribution networks are changing greatly because of the development of industry. Reactive power optimization considering single invariable load may cause bad compensation effect for some load patterns. In this paper, a fuzzy optimal model of multiple loads in distributed network is proposed to meet the demand of all the load patterns, and it is optimized by improved fuzzy traversal algorithm. Actual computation shows that this method can improve the whole optimization effect as well as good network loss and power quality under multiple loads mode by comparing with the common method.
