Cascade hydropower station aggregation dimension reduction compensation benefit distribution method based on cooperative game and comprehensive weighting

Abstract

The invention relates to a cascade hydropower station aggregation dimension reduction compensation benefit distribution method based on cooperative game and comprehensive empowerment, and aims to solve the problems of low calculation efficiency caused by too many distribution subjects and limitation of a traditional simple method in compensation benefit distribution when benefits are distributed by adopting a cooperative game theory. According to the method, firstly, the cascade hydropower stations are aggregated and dimensionally reduced to form a plurality of subjects according to a certainprinciple, secondly, compensation benefits among the subjects are distributed based on the cooperative game theory, and finally, the compensation benefits among the power stations are further distributed inside the aggregated subjects according to the idea of comprehensive empowerment. The embodiment shows that the method can scientifically quantify the compensation relation and the power generation compensation benefit between a large number of cascade hydropower stations, and reasonably distributes the power generation benefit increment to each power station.

Description

technical field [0001] The invention relates to the field of optimal dispatching of cascade hydropower stations in a river basin, in particular to a power generation compensation benefit coupling dimension reduction distribution method based on cooperative game and comprehensive weighting for a large number of cascade hydropower stations. Background technique [0002] The cascade hydropower station can greatly improve the overall power generation economic benefits of the cascade through joint dispatching, mainly because the cascade hydropower station will use its own adjustment performance to change the distribution of water energy resources in time and space during the dispatching operation process, so that the upstream power station will have a negative impact on the downstream power station. certain compensation. Therefore, how to quantify the power generation compensation benefits of cascade hydropower stations and distribute the power generation compensation benefits am...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the low calculation efficiency due to the excessive number of distribution subjects and the limitations of the traditional simple method in the distribution of benefits when using cooperative game theory to distribute benefits, and proposes a method based on cooperative game and comprehensive The empowered cascade hydropower station aggregate dimensionality reduction compensation benefit distribution method, this method first aggregates the cascade hydropower station dimensionality reduction to form several subjects according to certain principles, secondly distributes the compensation benefits among the subjects based on the cooperative game theory, and finally in each aggregate subject according to the " The idea of ​​"comprehensive empowerment" further distributes the compensation benefits among various power stations
