Cooperative game and DEA (Data Envelopment Analysis) based method for sharing fixed cost of power transmission system

Abstract

The invention discloses a cooperative game and DEA (Data Envelopment Analysis) based method for sharing the fixed cost of a power transmission system. According to the method, a coalitional game model in a DEA framework is established, a method for sharing the fixed cost of the power transmission system with a nucleolus method is proposed based on a cooperative game and DEA from the perspective of multi-attribute decisions, the DEA and coalitional game based sharing of the fixed cost of the power transmission system is calculated under the condition that area constraints are ensured, and an optimal and reasonable weight is calculated within a limited weight range, so that each user obtains a satisfied sharing result and benefit maximization of each user is satisfied.

Description

technical field [0001] The invention relates to a method for apportioning fixed costs of a power transmission system based on cooperative game and DEA, in particular to a method for apportioning fixed costs in the case of traditional power generation, and belongs to the field of cost apportionment. Background technique [0002] There is a mapping relationship between the fixed cost of a general transmission system and a single load (or power generation) electricity, which is called cost-energy mapping. Research shows that the topological structure of cost-electricity mapping is complex, showing strong nonlinearity, discontinuity, high dimensionality and multi-period characteristics. That is to say, the information flow between the use of expenses or benefits and the payment of expenses is uncertain and complicated. At the same time, for grid operators who do not aim at profit, their fixed costs must be allocated reasonably, fairly and completely to users (users of fixed cos...

Problems solved by technology

This is mainly because the power network is a monopoly operation, and all loads and generators must use the same power network at the same time, and the complex interactions between them jointly generate fixed costs, and it is usually impossible to distinguish the actual interaction responsibility in reality. do it

Therefore, the allocation of the fixed cost of the transmission system is a difficult problem that must be solved

[0009] There are many methods for calculating and apportioning transmission costs at home and abroad. On the whole, all methods cannot fairly allocate the fixed costs of transmission to each power generation that uses the transmission network while taking into account the complete recovery of transmission costs and the provision of economic signals. Therefore, no mature theory has been formed on the transmission pricing system so far. The practices of various countries are far apart, and there is still a large gap between theory and practice.
