The invention discloses a brainstorm-based scheduling method for the economic environment of a thermal power plant. The steps include: step 1, determining the mathematical model of the environmental economic scheduling problem of the thermal power plant; step 2, obtaining various parameters in the model; step 3, obtaining the environment The initial feasible scheduling set of the economic scheduling problem; Step 4, evaluate the feasible scheduling set; Step 5, update the feasible scheduling; Step 6, judge whether the entire feasible scheduling is updated; Step 7, evaluate the non-inferior scheduling in the external archive set The solution set is updated; step 8, iteratively outputs the final feasible scheduling scheme, and it is completed. The method of the present invention uses the thermal power plant as the power supply system, utilizes the collection and analysis of the data of the power system and the thermal power plant, and combines the brainstorming optimization algorithm based on the idea of clustering and variation to realize the solution to the thermal power plant economic scheduling problem that requires comprehensive environmental protection solve.
Description
technical field [0001] The invention belongs to the technical field of intelligent control, and relates to a brainstorm-based scheduling method for the economic environment of a thermal power plant. Background technique [0002] Thermal power generation is the main force of power supply at present. Since thermal power plants emit a large amount of harmful gases such as sulfur oxides, nitrogen oxides, and carbon dioxide, it not only directly pollutes the atmospheric environment, but also leads to the greenhouse effect. Therefore, comprehensive consideration of environmental protection and economic The research on the environment-economic dispatching problem of the power system with benefits not only has important theoretical significance, but also is the most realistic choice for the sustainable development strategy of energy and power. If pollution emissions are considered, the original single-objective optimization problem will become a multi-objective optimization problem,...
