China power system transformation project has two aspects. First of all, it outlines the current situation of China's power system transformation and conducts a comprehensive discussion on the global power system transformation, including a comprehensive review of all possible sources of power system flexibility (generation side, grid infrastructure, energy storage and demand side response), as well as a detailed discussion on the market, policy and regulatory framework, and how to effectively improve the power system Flexible operation capability. Secondly, based on the new policy scenario and sustainable development scenario in IEA's world energy outlook 2018, this report makes a detailed model analysis of China's power system in 2035. Under the new policy scenario, the establishment of the spot market and the trans provincial and trans regional electric power transaction are identified as two main factors to improve the operation efficiency of China's system. In order to absorb the high proportion of volatile renewable energy consistent with the sustainable development scenario in world energy outlook 2018, activate the demand side, especially the electric vehicle, and use the energy storage purposefully, for Canada The transformation of power system in China is very important.
