Basin cascade hydropower station group compensation benefit solving and benefit distribution method

Abstract

The invention discloses a compensation benefit solving and benefit distribution method suitable for a cascade hydropower station group of a drainage basin. The method comprises: proposing a solution thought for obtaining the compensation benefit of any benefit application power station of the basin cascade for each downstream power station; determining an objective function based on a solving idea, determining constraint conditions in combination with actual scheduling conditions of the basin, determining a solving algorithm, and establishing a basin cascade compensation benefit model; and calculating to obtain the pairwise relationship between the benefit application power station and each downstream power station through the model. Based on the TOPSIS theory, a compensation benefit distribution method for the cascade existence of a plurality of benefit application power stations is established. According to the method, a solving thought for obtaining the compensation benefit of any benefit application power station of the cascade hydropower station group is provided, the proposed benefit distribution method takes an approximate ideal value as an optimal solution, the starting point of pursuing benefit maximization of each subject is met, the calculation result is comprehensive, and the distribution method is scientific, reasonable and reliable.

Description

technical field [0001] The invention relates to the field of benefit compensation for cascade hydropower station groups in the water conservancy and electric power industry, and in particular to a compensation benefit solution and benefit distribution method for any benefit hydropower station in a river basin cascade to a downstream power station. Background technique [0002] my country's hydropower development has formed a "watershed, cascade, rolling, comprehensive" development model, such as the Yangtze River cascade, the Wujiang cascade, the Yellow River cascade, and the Lancang River cascade. The cascade development model of hydropower stations makes the compensation relationship between the hydropower stations more complicated. The leading hydropower stations in the upstream area and other power stations with better regulation performance use the advantage of storage capacity to store water in order to meet the requirements of power generation, irrigation, shipping, an...

Problems solved by technology

[0005] Problems existing in the current research content: content 1 only considers the conventional influencing factors of optimal dispatching of power plants, without considering the actual situation of dispatching, and only proposes the solution to the compensation benefits of leading power plants, but other power plants with better regulation performance in the cascade of the river basin also play a role However, it is not known how to calculate the compensation benefits of power plants with better regulation performance other than the leading power plant. The compensation benefit distribution methods listed in content 2 have their own advantages and disadvantages. In actual operation, there are mainly the following problems: ① Proportion The allocation method has not undergone in-depth research, lacks a theoretical basis, and easily conceals key factors that affect the distribution of compensation benefits

③Subjective comprehensive analysis method weight score is evaluated by experts, which has a lot of subjectivity and is easily questioned by all parties; the average deviation method believes that the average of the distribution results is the most ideal distribution result, and the greater the deviation of the index, the less ideal , the worse the importance, this does not meet the actual needs; the greater the entropy weight of the index defined by the entropy weight method (the greater the degree of discrimination of the distribution results), the better the distribution effect, but the most disordered distribution result does not mean that the method is more effective. ideal
