Regional environment-power system collaborative optimization method considering atmospheric pollution

Abstract

The invention discloses a regional environment-power system collaborative optimization method considering atmospheric pollution, and the method comprises the steps: firstly, calculating a comprehensive influence coefficient of power generation of each unit in a region on AQI of a main city by a corresponding relationship between the power generation amount and the discharge capacity, a corresponding relationship between the pollutant concentration and the AQI, and a Gaussian diffusion model of a continuous point source, and building a space-time pollution coordinate system; dividing the space-time points into core points and non-core points according to AQI predicted values, calculating a threshold value of the AQI of the core points influenced by power generation of the units in the region and a control coefficient of the AQI of the non-core points influenced by power generation of the units in the region, and establishing an optimization model taking the minimum power purchase cost and the minimum comprehensive influence of the power generation of the units in the region on the AQI of the non-core points as targets; and then solving the optimization model by adopting an NSGA-II algorithm, and finally selecting an optimal compromise solution as an optimal output result based on a fuzzy set theory, namely, the output power of each unit in different periods. According to the design, air pollution is effectively relieved.

Description

technical field [0001] The invention belongs to the field of power system optimization, and in particular relates to a regional environment-power system collaborative optimization method considering air pollution. Background technique [0002] With the increasing environmental problems caused by the emission of polluting gases, continuous smog has seriously affected people's normal work, study, and life. It is urgent to prevent and control air pollution and protect public health. [0003] As one of the most basic and largest industries in today's social and economic development, the power industry actively responds to the country's call to carry out energy conservation and emission reduction work. At present, there are a large number of literatures that consider environmental costs when studying power trading plans, and alleviate the impact of power generation and power consumption on air quality by introducing the optimization goal of minimizing the total amount of pollutan...

Problems solved by technology

Although many policies based on this idea have also obviously controlled the total amount of air pollutant emissions, these literatures have ignored the characteristics of the temporal and spatial distribution of air pollution and other meteorological factors that affect air quality, and lack of research on key areas and prominent periods. Process control is unsustainable, so in practice, the air quality in many areas or densely populated urban areas still frequently suffers from continuous severe and severe pollution
