Optimization on Chinese Power Source Structure Based on the Objective Programming

China´s thermal-power-led power structure has caused serious environmental pollution problems. The Energy Development Eleventh Five-year Plan of China proposes that China should reduce the emissions of the main pollutants and optimize the power structure. In this paper, we build the programming model to optimize the electric power structure and constraint the electricity production from the perspective of the economic and the environment. Then sensitivity analysis is undertaken on the basis of the optimized results. Through changing the order of priority of economic and environmental as well as emission performance of SO₂ and CO₂, the clean energy power generation may reach 27.68 % at the end of Eleventh Five-Year Plan , the SO₂ and CO₂ emissions go to 7.5 million tons and 2.32 billion tons. The research shows that the emission performance of CO₂ should at most be 834.75 g/kWh; the total emission constraint can be satisfied.
