摘要
随着分布式发电的发展和电力用户对电能质量的要求越来越严格,对电能质量进行综合评估和治理越来越重要。现有的电能质量综合评估方法并不能很好地适用于分布式电源。为做好分布式电源并网可行性分析,加强对电能质量治理工作的引导,需要提出一种适用于分布式电源的电能质量综合评估新方法。文中提出采用数据包络分析的分布式电源电能质量综合评估方法,建构分布式电源电能质量的综合评估指标体系。最后,算例表明,采用所提方法可以对比评对象的效率值,并选择出最优方案。数据包络分析方法适用于综合评估配电网的电能质量指标,在工程上具有显著的可行性。
With the development of the distributed generation systems and more and more power customers are strict with power quality, comprehensive evaluations of power quality and improvements have become more and more important. However, the existing power quality comprehensive evaluation methods are not applicable to distributed generation. In order to study the feasibility of the distributed generation integration, and strengthen the positive guidance for improving the power quality, a new power quality comprehensive evaluation method is necessary for distributed generation. The power quality comprehensive evaluation method for distributed generation system using data envelopment analysis (DEA) was proposed and the comprehensive evaluation index system was built. Finally, a case study showed that the proposed method can compare each appraisal object's efficiency values and then get the ideal solution. The DEA method is suitable for the evaluation of power quality indices in distribution systems, and has practical significance for engineering.
