Description
Summary:With the increasing problem of air pollution, improving atmospheric quality has been attracting more attentions in the worldwide, especially in coal-burning areas. As an important emission source of atmospheric pollutant, the scheduling strategy of coal-fired power plants has a significant impact on atmospheric quality. In this paper, a day-ahead unit commitment and dispatch model of power system considering with atmospheric quality is developed. Due to the fact that atmospheric quality not only depends on pollutant emissions but also depends on meteorological conditions of pollutant diffusion, the atmospheric diffusion model is coupled with the unit commitment and dispatch model. In addition, robust optimization is adopted to ensure the robustness of pollutant concentration constraints. The validity of the proposed model is demonstrated by case study results.
