摘要
近些年电网公司对配电网投资持续加大,但缺乏一套科学合理的配电网项目投资效益评估体系。在此背景下,首先从装备水平、网架结构、供电能力、新增供电量等方面构建了两级配电网项目投资效益评估指标体系,并使用层次分析法与熵值法分别对评估体系中各指标计算权重,以及使用博弈论方法综合二者权重形成各指标最终权重;最后,采用核主成分分析方法抽取各项目评价指标数据的主成分,再基于主成分综合得分和投资金额对各项目投资效益优劣进行排序。仿真算例表明该方法可以科学合理评价配电网项目投资效益,有效地指导配电网建设与改造。
In recent years,power grid companies continue to increase their investment in distribution network.However there is a lack of a scientific and reasonable investment benefit evaluation system for distribution network projects.In order to solve this problem,this paper firstly constructs a two-level distribution network project investment benefit evaluation index system from the aspects of equipment level,grid structure,power supply capacity,and newly added power supply.Secondly,the analytic hierarchy process and entropy method are used to calculate the weight of each index in the evaluation system.Then the game theory method is used to synthesize the two weights to form the final weight of each index.Finally,the principal components of the evaluation index data of each project are extracted by the nuclear principal component analysis method,and the investment benefits of each project are sorted based on the comprehensive score of the principal components and the investment amount.Numerical simulation examples show this method can scientifically and reasonably evaluate the investment benefits of distribution network projects and effectively guide the construction and transformation of distribution network.
