Two-Way Coupling Optimization of Power Source Structure Based on the Constraint of SO2 Emission

Abstract

For a long time, China's coal-based energy structure, as well as thermal-power-led power structure, has caused serious environmental pollution problems. As the proportion of Chinapsilas power source structure is not so reasonable, it receives growing attention. 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 SO2 emissions decreases by almost 22.35, in 2010 compared to 2005. The proportion of thermal power goes down to 72.2, from the former 79.64, through adjustment of the power structure, and the clean energy be 27.8. Through the power structure optimization, the emission quantity of SO2 is greatly decreased and could reach the Chinapsilas reduction target.
