基于云理论的居民负荷集体谐波概率分布
Collective Harmonic Distribution of Residential Loads Based on Cloud Theory
摘要
Abstract
With the ever widening application of power electronic based residential loads and new energy devices in distribution systems,very considerable collective harmonics that have non-negligible impacts on the power systems have been generated. Therefore,a collective harmonic assessment method based on the cloud theory for residential loads is presented. The fundamental theory of the cloud model and cloud transform is introduced briefly firstly.And then the procedure of the collective harmonic assessment of residential loads is illustrated in details.The analysis results of practical cases prove that the cloud transform is capable of fitting the harmonic current distribution curves in high precision,and presenting the multi-modal characteristics of the distribution curves well.The 95% maximum probability calculated with the cloud transform is much more accurate than the normal distribution method does.The research results are meaningful to analyze the residential harmonic sources and determine the harmonic control and supervision measures.关键词
