Investment Optimization Strategy Of Distribution Network Based On Investment Benefit

With the improvement of the national economy,the power load has increased steadily.In order to meet the people's growing demand for electricity,grid companies need to continuously invest to expand the scale of the distribution network and optimize the structure of the distribution network.Therefore,in the face of the continuous investment of a large amount of construction funds,it is of great significance to use scientific methods to comprehensively evaluate the distribution network investment effect to improve the scientificity of investment and rationally arrange the distribution network construction.This paper builds a distribution network input-output evaluation index system by studying the main factors that affect the formulation of power grid investment strategies;based on historical data,quantitative analysis of the distribution network input-output correlation,with the goal of maximizing the comprehensive distribution network benefits.Consider the precise investment strategy of the distribution network that differs from city to city,improve the investment benefits of the power grid,and promote the scientific and sustainable development of the power grid.The main work of this paper is as follows:(1)Build a set of scientific and quantified distribution network input-output evaluation index system,and solve the problem of distribution by adopting a reasonable index simplification method to solve the problem of complicated and redundant indexes in the existing distribution network evaluation index system.The technical difficulty of low input efficiency and poor accuracy of the network input-output evaluation.(2)In order to solve the complex and changeable problem of distribution network input-output correlation.In-depth mining historical data of distribution network investment,combed and analyzed the relationship between the distribution network input indicators and output indicators.(3)Formulated an optimized investment strategy for power grid companies in the context of incremental distribution networks to maximize the investment benefits of multiple entities.The investment entities and investment models of the incremental distribution network are analyzed,the influencing factors of the income distribution of multiple investment entities are studied in depth,and the optimization model of the multi-agent investment distribution of the incremental distribution network is established based on the cooperative game theory.
