Optimization of Electric Power Source Structure under the Constraint of CO2 Emission

For a long time, China´s coal-based energy structure, as well as thermal-power-led power structure, has caused serious environmental pollution problems. To achieve the emissions constraints of major pollutants till the end of Eleventh Five-Year Plan, and optimize China´s power structure, the research builds the electricity production and environmental constraints coupling optimization model and proposes the optimal program of China´s power structure, accompanied with the analysis of the potential effect and validity of the program. After optimization, the CO₂ emissions decreases by 7.61% in 2010 compared to 2005, the proportion of thermal power goes down to 72.2% from the former 79.64%,and the clean energy be 27.8%. Through the power structure adjust, the emission quantity of CO₂ is greatly decreased.
