Abstract
Carbon tax is an important regulatory approach for the decarbonization of the power system. However, with the continuous increase of the penetration rate of renewable energy in the power system, it is important to research how carbon tax pricing levels affect power system carbon emission reduction. To this end, an economic dispatch model of power system that considers the carbon tax and wind power uncertainty is proposed. The model is optimized to minimize carbon emissions costs, power generation operating costs, and generator fixed costs. This paper studies the promotion effect of carbon tax on power system carbon reduction under various wind power penetration rates. Based on the modified IEEE 39-bus power system and MATLAB/YLAMIP simulation platform with Gurobi solver, the numerical analysis of cases show that the proposed model can effectively promote the system to reduce carbon emissions. In addition, the optimal carbon tax pricing levels under different wind power penetration rates can be derived. This provides a theoretical reference for formulating reasonable carbon tax pricing levels to better promote decarbonization in power systems with different wind penetration rates.
