【 摘 要 】

The coal capacity reduction policy has made great impact on the pattern of coal transportation and power transmission across regions. In this paper, the total coal consumption control and renewable energy quota constraint target were decomposed into regional constraints for the multi-region power generation energy development and transmission model, which was constructed by the energy technology model. Then the baseline and intensive scenarios were designed for coal and power transmission optimization, while the whole country was divided into seven regions according to the sending and receiving relationships. The results show that, under the background of coal capacity reduction, the power transmission scale will continue to increase quickly, with the ratio between coal and electricity transmission declining, to be 3.3 in 2020, 1.8∼2.0 in 2030 and 1.2∼1.5 in 2050 for different scenarios.
