Benefit compensation method and system for cascade leading hydropower stations in the basin

Abstract

The invention relates to a benefit compensation method and system for a cascade leading hydropower station. The system comprises a client layer, comprising a basic information management module, an optimization calculation module and a benefit compensation calculation module, a data server layer which is used for storing basic information data, dispatch calculation data and benefit distribution data and an external interface which comprises API, DBMS, URL and Web Service, wherein the basic information management module is used for managing and maintaining basic parameters and characteristic curves of the hydropower station, the optimization calculation module is used for calculating the increasing electricity output of the leading hydropower station in maximal cascaded generating capacity model for a downstream cascade hydropower station, and the benefit compensation calculation module is used for determining a final compensation benefit allocation method. The benefit compensation method and system for the cascade leading hydropower station consider not only conventional factors of hydropower station dispatching, but also the problem that a lot of river basins all face construction of large-scale water diversion projects, so that calculation results of the benefit compensation method are more comprehensive, and have broader practical values.

Description

technical field [0001] The invention relates to the field of benefit compensation for leading hydropower stations in the electric power industry, in particular to a benefit compensation method for cascaded leading hydropower stations in a river basin. Background technique [0002] The commissioning of the leading hydropower station in the basin has brought considerable economic benefits to the downstream cascade hydropower stations, but the problem of benefit compensation for the sustainable development of the cascade hydropower station in the basin has not been well resolved, seriously restricting the development of hydropower. In order to meet the comprehensive utilization requirements of downstream power generation and water supply, large-scale hydropower stations with good upstream regulation performance sacrifice their own power generation benefits, so that the middle and lower reaches of the river basin can obtain significant economic and social benefits, but the benefi...

[0004] Problems in the current research content: Content 1 only considers the conventional factors of power station dispatching, but many river basins are currently facing the construction of large-scale water diversion projects, and this factor has not been considered in dispatching; in the process of calculating compensation benefits in Content 2, the amount of calculation will increase As the number of power stations increases exponentially, when the number of power stations reaches a certain number, the curse of dimensionality will appear. Neural networks, decision support systems, and large-scale system decomposition and coordination technologies are mainly used to solve the curse of dimensionality. However, these methods It is easy to fall into the local optimal solution, or the problem that the result of multiple calculations is not unique; the various methods of content 3 compensation benefit distribution are not practical, and there are the following specific problems: ① The proportional distribution method is simple to implement, but it lacks the compensation benefit The clear calculation cannot reflect the actual benefits and benefits of both parties. In the specific implementation, there are often differences between the parties on the size of the compensation benefits and the sharing ratio; ②The single-factor allocation method is simple and clear, but the compensation for the same cascade hydropower The results obtained by selecting different indicators in the benefit allocation are quite different, and there is a certain one-sidedness; ③Comprehensive factor method has improved compared with the single factor method, but it needs to manually determine the weight or select reference factors, which is highly subjective
