Hydropower station peak regulation scheduling method

Abstract

The invention discloses a hydropower station peak regulation scheduling method, and belongs to the field of hydropower station peak regulation scheduling. According to the method, existing hydropowerpeak regulation scheduling model constraint conditions are converted into water level constraints through hydraulic connection between hydropower station scheduling-period periods, a real-time water level gallery is calculated, and the problem that generated individuals are not suitable for actual working conditions due to the fact that hydropower peak regulation scheduling is subjected to a largenumber of constraints and the solution feasible region is very small is solved; on the basis, Gaussian distribution is replaced by truncated normal distribution, population diffusion and optimizationare carried out based on a random fractal algorithm, and the diffusion process is carried out in a water level gallery, so that constraint conditions are met, the discrete diversity of an original algorithm is guaranteed, and the correction frequency in calculation can be reduced; the randomness of a solving result of an existing method is overcome, the stability of the solving result of the model is improved, and efficient utilization of water energy resources is promoted.

Description

technical field [0001] The invention belongs to the field of peak-shaving scheduling of hydropower stations, and more specifically relates to a method for peak-shaving scheduling of hydropower stations. Background technique [0002] Peak-shaving scheduling of hydropower stations refers to the use of hydropower stations to undertake the peak-shaving work of the power grid to solve the problem of coordination between power grid load distribution and power station output. Ideally, the power grid aims to achieve the most stable residual load, and can allocate the total power generation of the hydropower station to each period to obtain the output of the hydropower station in each period. However, the output of the hydropower station often cannot reach the ideal output, because The output of hydropower stations is not only affected by incoming water and installed capacity, but also by water level and flow constraints brought about by flood control, ecological and other dispatchin...
