Electricity price cross-subsidization supervisory evaluation method based on game theory

Abstract

The invention discloses an electricity price cross-subsidization supervisory evaluation method based on a game theory, and belongs to the technical field of electricity price cross-subsidization supervisory evaluation methods in an electricity market. The method includes building theoretical models related to subjects including local governments G, power grid enterprises N, large industrial electricity users L and general industrial and commercial electricity users S. Chinese residential electricity consumption is only 12%, residential electricity prices are constant for a long time, and residential user electricity consumption H is exogenous in the models. Market behavior selection of the local governments, the power grid enterprises and classified users is analyzed according to game behaviors of the local governments, the power grid enterprises and the classified users in the electricity market, and electricity price cross-subsidization supervising strategy selection of the local governments in electricity market games is evaluated more meticulously and accurately by three-stage cycle game model equilibrium results.

Description

technical field [0001] The invention relates to a supervision and evaluation method for electricity price cross-subsidy in an electric power market, in particular to a method for supervision and evaluation of electricity price cross-subsidy based on game theory. Background technique [0002] my country's mixed regulatory agency structure is composed of industrial and departmental agencies at the central and local levels. Another structural feature of the regulatory structure is the existence of a hierarchical structure between central and local regulatory entities. There are local development and reform committees at each level of government, and likewise, there are a number of regional executive agencies to assist local development and reform committees. The separation of powers between the National Development and Reform Commission and the local Development and Reform Commission is mainly manifested in the following: the former is usually responsible for controlling the a...

AI Technical Summary

Problems solved by technology

The invention considered factors such as load, government supervision, and project cost, but did not detail the electricity consumption situation, did not consider the differences between large industrial enterprises and general industrial and commercial enterprises, and the differences between perfect and imperfect supervision by local governments

[0004] The patent document with the publication number CN107203898A discloses a cross-subsidy calculation and evaluation method, which solves the technical problem of inaccurate cross-subsidy calculation methods in the prior art. The cross-subsidy calculation and evaluation method of the invention includes: obtaining the average power purchase price and the transmission and distribution price of each voltage level under each power consumption type, and determine the theoretical sales price according to the average power purchase price and transmission and distribution price; obtain the actual electricity sales unit price and actual electricity sales volume of each voltage level under each power consumption type, and based on the actual The unit price of electricity sales and the theoretical sales price of electricity determine the cross-subsidy amount of each voltage level under each user type

This invention divides users into four categories: large industrial users, general industrial and commercial users and their electricity consumption, residential electricity consumption and agricultural electricity consumption. The impact of local government supervision is not considered, and the calculation results are not accurate enough.
