In recent years, power grid companies continue to increase investment in distribution network, but there is a lack of a scientific and reasonable distribution network project investment benefit evaluation method. Firstly, a two-layer distribution network investment evaluation index system is constructed from the aspects of equipment level, power supply capacity, loss reduction and power consumption increase. Then, analytic hierarchy process and entropy method are used to calculate the weight of each evaluation index respectively, and the final weight of each index is calculated by game theory.The principal component of each evaluation index is extracted by the kernel principal component analysis, and the investment benefit of each project is ranked based on the comprehensive score of principal component. This method can evaluate the investment benefit of distribution network project scientifically and reasonably, and then guide the construction and reconstruction of distribution network effectively.
