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.
