摘要
近年不少地区配电网的负荷变动较大,仅考虑单一负荷状态下的无功规划方案有可能导致一些负荷模式的补偿效果极差。本文提出了兼顾多种负荷模式的配电网多负荷模糊最优模型,并使用改进遍历算法优化。实际计算表明,与常规优化方法相比,此方法可兼顾多种负荷模式下网络损耗与电能质量,能提高整体优化效果。
In recent years, loads of many urban distribution networks are changing greatly because of the development of industry. Reactive power optimization considering single in- variable load may cause bad compensation effect for some load patterns. In this paper, a fuzzy optimal model of multi- ple loads in distributed network is proposed to meet the de- mand of all the load patterns, and it is optimized by im- proved 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 multi- ple loads mode by comparing with the common method.
