Problems solved by technology

On the one hand, if the power grid increases investment in asset projects at will, the rapid growth of effective assets will lead to falsely high permitted costs and permitted income, and the transmission and distribution price will face upward pressure
In order to ensure coordinated development with the electricity sales market, the advanced development of grid investment will be restrained
On the other hand, investment and cost determine the transmission and distribution price together, and in the case of limited price space, excessive investment will cause the cost to be over-reduced

Abstract

The invention relates to a power grid investment benefit evaluation method suitable for power transmission and distribution price reform, and the method comprises the steps: S1, constructing a power grid investment benefit evaluation index system suitable for power transmission and distribution price reform, and carrying out the calculation or budget of each index in the evaluation index system; S2, assigning values to the evaluation indexes by adopting an efficacy coefficient method according to the index calculation values and the measurement standards; S3, determining the weight of each index by adopting a method of combining an analytic hierarchy process and an entropy weight method; S4, establishing a power grid investment historical benefit evaluation model suitable for power transmission and distribution price reform; S5, establishing a power grid investment current situation benefit evaluation model suitable for power transmission and distribution price reform; S6, establishinga power grid investment future prediction benefit evaluation model suitable for power transmission and distribution price reform; and S7, establishing a power grid investment dynamic benefit evaluation model suitable for power transmission and distribution price reform. The comprehensive evaluation method is used for evaluating the dynamic investment benefit of the power grid, and references areprovided for the overall investment effect of the power grid and future investment decisions.

Description

technical field [0001] The invention belongs to the technical field of investment decision-making of power grid companies, and in particular relates to a grid investment benefit evaluation method adapted to the reform of power transmission and distribution prices. Background technique [0002] At present, Tianjin has been included in the pilot scope of transmission and distribution price reform. Under the new transmission and distribution price mechanism, the investment scale of power grid enterprises may gradually decrease, and government supervision has higher requirements for output effects such as investment efficiency and investment return effect . On the one hand, if the power grid increases investment in asset projects at will, the rapid growth of effective assets will lead to falsely high permitted costs and permitted income, and the price of transmission and distribution will face upward pressure. In order to ensure coordinated development with the electricity sale...
