Embodiment

[0093] This embodiment mainly takes the four-station variable blade angle adjustment in Huai'an and the three-station frequency conversion adjustment in Huaiyin as examples, and compares the improved algorithm with the traditional dynamic programming successive approximation algorithm and the large-scale system decomposition and aggregation algorithm to reflect the advantages of the algorithm in the solution results .

[0094] Depend on figure 2 and image 3 It can be seen that whether it is the four-station variable blade angle adjustment in Huai'an or the frequency conversion adjustment at the three Huaiyin stations, the relative cost savings of the above three solution algorithms have the same change trend. However, the results of the improved algorithm are better than the large system decomposition-aggregation algorithm and the dynamic programming successive approximation algorithm. The large system decomposition-aggregation algorithm is better than the dynamic programmi...

Abstract

The invention discloses a pump station scheduling optimization method. The method includes the following steps: establishing a mathematical model of a pump station; considering a scheduling mode of the pump station, and using a blade angle or a rotation speed as a variable to simplify the mathematical model of optimization scheduling; and optimizing and converting multiple units in the pump station into a single unit to optimize and reduce dimensionality through analyzing the mathematical model and combining an actual situation of the pump station, designing an algorithm for optimization of the single unit to obtain an optimal solution by solving, and aggregating a single-unit solving result into a global optimal solution of optimization of the multiple units in the station in a dynamic planning manner. According to the pump station scheduling optimization method designed in the invention, a global optimal scheduling scheme can be obtained by solving on the premise of ensuring that constraint conditions are met, and scheduling costs are saved.

Description

technical field [0001] The invention relates to power electronics technology, in particular to a pumping station scheduling optimization method. Background technique [0002] In order to develop the economy and solve the problem of unreasonable distribution of water resources, many countries have built many cross-basin dispatching projects. my country's South-to-North Water Diversion Project has attracted worldwide attention. The east route project of the South-to-North Water Diversion Project has been put into operation, and the data show that the current annual operating cost of the east route project has reached 3 billion to 4 billion yuan. Running costs are huge. The current research mainly uses traditional optimization algorithms, large system theory and modern heuristic algorithms. The above algorithm adopts the general solution method of optimization algorithm, without corresponding analysis, there is a "curse of dimensionality" problem, and the amount of calculati...
