Embodiment

[0105] Taking the problem of environment-economic dispatching of the power system of 6 units in a thermal power plant as an example, the parameter setting involved in the implementation of the method of the present invention is described.

[0106] Set the parameters in step 1 and step 2: the mathematical model of the environmental economic scheduling problem is shown in formula (1)-(7), where the fuel consumption characteristics of the i-th generator set in formula (2) The coefficient matrices of the constant term, the first-order term and the second-order term of are all fixed values ​​of the system, which are respectively:

[0107] a i =[10 10 20 10 20 10]

[0108] b i =[200 150 180 100 180 150]

[0109] c i =[100 120 40 60 40 100]

[0110] In formula (3), the correlation coefficients of the constant term, the first term and the quadratic term coefficient matrix exponent term of the pollution emission characteristics of the i-th generating set are all fixed values ​​of ...

Abstract

The invention discloses a brainstorming-based thermal power plant economic environment scheduling method. The method includes the following steps of: determining mathematical models of thermal power plant environmental economic scheduling problems; step 2, obtaining various parameters in the models; step 3, obtaining an initial feasible scheduling set of the thermal power plant environmental economic scheduling problems; step 4, evaluating the feasible scheduling set; step 5, updating the feasible scheduling set; step 6, judging whether entire feasible scheduling is updated completely; step 7, updating a non-inferior scheduling solution set in an external archiving set; step 8, performing iterative output of a final feasible scheduling scheme, and the method terminates. According to the brainstorming-based thermal power plant economic environment scheduling method of the invention, a thermal power plant is adopted as a power supply system, and solutions to thermal power plant economic scheduling problems which are required by comprehensive environmental protection can be realized through collection and analysis of data of a power system and the thermal power plant and a brainstorming optimization algorithm based clustering and variation ideas.

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,...
