(4) combined with the national economic and social development stage of industrialization and overall carbon emissions, considering the national development planning period the total amount of constraint four range carbon emission trajectory model is established on the basis of power system planning model based on the constraint of carbon emission trajectories under the constraint of carbon emission low carbon economy. The yearly planning period, considering the model framework constraints in the overall emission trajectory of the electric power industry, the power system operation planning problem of carbon emissions and carbon capture power plant as the focus of the study, the carbon emissions caused by economic cost and carbon capture power plant construction costs included in the objective function for a provincial electric power.
