Generation dispatch with air pollutant dispersion consideration

This paper addresses a new generation dispatch method with constraints of geographical emission distribution of air pollutant dispersion. Traditionally, generation dispatch methodology considers the total cost and total amount of emission. However, even for the same amount of emission, the effect of emitted SO₂, NOx and particles might be completed different due to the geographical distribution and meteorological condition. In this work, pollutants distribution associated with geographical distribution of power plants and meteorological condition will be integrated into the generation dispatch models. The generation dispatch pattern is thus established with acceptable air pollution level for a specified location. A highly efficient interior point method is employed to solve the proposed model. A standard IEEE test system is employed to demonstrate the proposed model and algorithms.
