Abstract
Abstract Electricity production is an important source of CO 2 emissions in China. Using a multi-objective model and a fuzzy multi-objective optimization linger programming method, this paper analyzes different scenarios for optimal allocation of China's power system in 2020. The results suggest that under low CO 2 reduction target, the fuel power plant should be highly developed besides coal-fired conventional plants, which in fact is impossible to form a fuel-driven power plant structure in China. When CO 2 reduction target is increased, natural gas combined cycle power plants should be developed vigorously. The coal-fired conventional power plants, hydropower plants and fuel power plants should play a lesser role in electricity generation. It is noteworthy that higher emission reduction targets do not cause greater generating cost. It is necessary for China to adjust its power generation structure from traditional coal-driven power plants to a diverse generation mix especially the development of plants using clean energy such as natural gas and hydropower. With rapid economy growth, China's power industry must develop strict CO 2 reduction targets, and emission reduction technology should be promoted in large-scale in China's electricity sector, as it does not lead to a higher increase in generating costs.
