Environment comprehensive management method for thermal power plant based on credibility fuzzy programming method

Abstract

The invention belongs to the technical field of energy system emission analysis and management, and especially relates to an environment comprehensive management method for a thermal power plant basedon the credibility fuzzy programming method. The management method comprises the steps: A, determining sulfur dioxide emission limitation, nitric oxide emission limitation and particulate matter emission limitation of a regional thermal power plant as fuzzy parameters, and determining carbon dioxide emission limitation as an interval parameter; B, establishing a thermal power plant environment comprehensive management system model considering a carbon transaction mechanism and air pollutant constraints; C, carrying out credibility interception on the constraints containing the fuzzy parameters by utilizing a credibility theory, and converting the nonlinear model into a linear model; D, solving the linear model, and quantifying the influence of different credibility levels on the power supply proportion and carbon quota distribution of the regional thermal power plant. According to the method, the uncertainty of the atmospheric pollutant emission limit value represented as the fuzzy number in the power system can be effectively processed, and the corresponding regional power system planning scheme can be obtained based on different fuzzy credibility levels.

Description

technical field [0001] The invention belongs to the technical field of analysis and management of energy system emissions, and in particular relates to a thermal power plant environmental comprehensive management method based on a reliability fuzzy programming method. Background technique [0002] With the rapid development of social economy and the continuous growth of population, the consumption of electricity has increased sharply, and the contradiction between energy supply and demand has gradually emerged. The power supply structure dominated by fossil energy such as coal and natural gas has led to the deterioration of the ecological environment. Sulfur and nitrate are the main pollutants in the flue gas emitted by thermal power plants. Such substances will cause serious pollution to the atmospheric environment, which in turn will cause acid rain and other natural disasters, threatening the human living environment. The particulate matter in the exhaust gas of thermal ...

AI Technical Summary

Problems solved by technology

For example, the lack of research and development of methods to characterize the complexity and multiple uncertainties of power systems cannot effectively take into account uncertain factors in time and space, so as to provide a more scientific and reasonable basis for decision-making

In addition, in terms of carbon dioxide emission management, there is a lack of introduction of a carbon trading mechanism, and the inability to flexibly allocate carbon emission quotas, so that thermal power plants can obtain greater benefits
