Embodiment
[0046] 1. First, introduce the principle of the method of the present invention, which specifically includes:
[0047] (1) The required data acquisition: mainly the peak-shaving benefits obtained through optimized calculations, the real-time output of cascaded hydropower stations, and the basic parameters of hydropower stations; among them, the peak-shaving benefits can be calculated by the power grid through optimization algorithms, and the optimization results are directly selected , The real-time output of cascaded hydropower stations and the basic parameters of hydropower stations can be collected by the grid dispatching center and the hydrological information department;
[0048] Peak shaving benefit distribution value solution: This method includes four steps, namely, marginal benefit solution step, opportunity cost solution step, power station comprehensive strength index solution step, and improved shapley value method solution step. The output of the first three steps is us...

The invention belongs to the field of peak load regulation benefit distribution of hydropower station, in particular to a method for allocating benefit of peak shaving among multi-stakeholder of cascade hydropower station group. The invention distributes peak load regulation benefit of cascade hydropower station group multi-interest main body through peak load regulation benefit obtained after optimization calculation, cascade hydropower station real-time output and basic parameters of hydropower station. Peak shaving benefit allocation method is divided into four modules, which are marginal benefit module, opportunity cost module, power station comprehensive strength index module and improved shapley value method module. The advantage of this system is that the benefit distribution mechanism of cascade hydropower peak shaving is not clear, Considering the marginal benefit of peak shaving, opportunity cost of peak shaving and comprehensive strength of hydropower station, the calculatedpeak shaving benefit value is more reasonable, which can better mobilize the enthusiasm of peak shaving of cascade hydropower station, and provide reference for power network personnel to distributepeak shaving benefit of cascade hydropower station.
Description
Technical field [0001] The invention belongs to the field of peak shaving benefit distribution of hydropower stations, and specifically relates to a method for the peak shaving benefit distribution of multi-stakeholder groups of cascaded hydropower stations. Background technique [0002] In recent years, the state has invested more and more in new energy power generation, and a large number of wind farms and photovoltaic power plants have been put into operation. However, due to the uncertainty and intermittent nature of wind power and photovoltaics, they have anti-peak shaving characteristics. Therefore, the integration of new energy power generation has become a big problem. In Northwest China, there are a large number of wind power and photovoltaic resources, but the phenomenon of abandoning wind and solar is serious, causing a lot of waste of resources. At present, the grid connection of new energy power generation is realized mainly through the peak shaving of thermal power...
