Investment Benefit Evaluation And Accurate Distribution Method Under Transmission And Distribution Price Reform

The State Grid Corporation clearly stated that the strategic goal of the new era company is to build a world-class energy Internet enterprise with excellent competitiveness.To build a world-class strong smart grid,we must first focus on promoting high-quality development of the grid.With the full implementation of the transmission and distribution price reforms in various provincial power grids,it marked the initial establishment of a transmission and distribution price mechanism based on permitted costs plus reasonable returns as a pricing method and a new electricity price supervision system.The transmission and distribution price reform has a great impact on grid investment and capital recovery.As a subject of supervision,grid companies pay more attention to investment benefits.The grid ’s investment requirements for projects have changed from "technically necessary and economically feasible" to "more Focus on economic benefits."This article first comprehensively combed the process of transmission and distribution price reform and analyzed the current situation to understand the impact of transmission and distribution price reform on grid investment,and then carried out the investment planning of grid companies and sorted out their strategic deployment and investment.direction;Then,establish a grid investment benefit evaluation index system that is suitable for the transmission and distribution price reform.These indicators are considered from multiple aspects,and try to fit the transmission and distribution price reform.The efficiency coefficient method and expert scoring method are used to separately measure the quantitative indicators and Qualitative indicators are scored,subj ective and objective methods are used to give index weights,linear weighted comprehensive evaluation methods are used to obtain evaluation scores,and then historical benefit evaluation,benefit status evaluation,comprehensive benefit evaluation,forecast benefit evaluation,and dynamic benefit evaluation models are established;Based on the establishment of the overall power grid and project investment benefit evaluation models,Establish and adapt the calculation model for the accurate allocation of grid project investment in power transmission and distribution price reform.Among them,the accurate allocation calculation method of grid project investment uses 0-1 planning to establish the model;finally,based on the previous establishment of the grid investment dynamic benefit evaluation model adapted to the transmission and distribution price reform and the accurate allocation calculation model for example analysis.This article establishes a dynamic benefit assessment model and a precise investment allocation model that are compatible with the transmission and distribution price reform,so that enterprises can flexibly respond to the changing market operating environment,and provide power grid companies with guarantees for investment benefits and accurate investment allocation in the production and operation process powerful tools.
