基于AHP和BP-Adaboost的低压电力用户价值评价方法

A value evaluation method of power user based on AHP and BP-Adaboost algorithms

传统的电力用户价值评价一般不区分高、低压电压等级,高压和低压用户适用指标各异且目前低压电力用户价值评价未见对应指标体系,为此,提出一种基于AHP和BP-Adaboost算法的低压电力用户价值评价方法。首先建立一套低压电力用户价值评价指标体系,并定义评分规则和等级划分规;然后则利用层次分析法(AHP)获取低压电力用户价值评价综合得分和等级;最后提出利用AHP和BP-Adaboost相结合的算法进行低压电力用户价值评价,得到低压电力用户综合得分和等级,并利用决定系数和准确度2个参数进行验证。算例仿真及其结果表明方法正确有效。

The traditional value evaluation of power users does not consider the high and low voltage levels generally.In fact,the applicable indicators of high voltage and low voltage users are different,especially,there is no corresponding indicator system for the current low voltage power user value evaluation.Therefore,this paper proposes a low voltage power user value evaluation method based on the AHP and BP Adaboost algorithms.Firstly,a set of low-voltage power user value evaluation index systems are established,and the scoring rules and grading rules are defined.Then the comprehensive scores and grades of low-voltage power user value evaluation are obtained by AHP.Finally,the calculation method combining AHP and BP Adaboost is proposed to evaluate the low-voltage power user value,and the comprehensive scores and grades of low-voltage power users are obtained after that.In addition,the two parameters of determination coefficient and accuracy are used for verification.The simulation results show that the method is correct and effective.
