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 CO
₂
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 CO
₂
is greatly decreased.
