Analysis of using integrated multi-energy model to promote development of renewable energy in Western China
With the continuous expansion in recent years, the installed capacity of renewable energy power in China had reached 650 GW by the end of 2017, accounting for 36.6% of the total installed capacity.The large-scale exploitation and utilization of renewable energy is an important measure to realize the transformation of energy structure and cope with climate change in China.However, China, especially in Western China, has a serious hydropower, wind power and solar power curtailment problem.In 2017, the amount of wind power curtailment and solar power curtailment in Northwest China reached 23.6 TWh and 6.7 TWh respectively, and the amount of hydropower curtailment in Southwest China was more than 45.6TWh.Integrated Multi-energy Model is an effective way to solve the problem of hydropower, wind power and solar power curtailment in Western China.The southwestern resource-based cities, based on the upper reaches of the Yangtze River and other large hydropower stations, and the northwest resource-based cities, relying on coal resources, have the conditions and advantages of building integrated multi-energy projects of wind, solar, water, thermal and storage power.Taking Wuhai of Inner Mongolia in Western China as an example, which is a typical resource-based city, by carrying out complementation with local thermal power resources, wind power, solar, hydropower and pumped storage power,it is estimated that the proportion of coal-fired power in Wuhai will be reduced from 97.52% in 2014 to 60.95%, and the proportion of renewable energy will be increased from 2.48% in 2014 to 39.05%.This provides reference for other resource-based cities in Western China to promote the development of renewable energy through the implementation of integrated multi-energy projects.
