At present, the construction of a new power system is a necessary move to achieve the dual-carbon goal, and it is imperative to increase the scale of renewable energy grid-connected. To this end, the "Implementation Plan" proposes specific measures to improve the adaptability of the new power system to a high proportion of renewable energy. What pain points do these specific measures point to? Liu Shiyu, assistant to the president of the General Electric Power Planning and Design Institute, pointed out in an interview with a reporter from China Energy Media that the "Implementation Plan" has put forward practical and operable policy measures to solve the problems of insufficient flexibility and insufficient adjustment capacity of the power system. It is conducive to accelerating the realization of effective and reliable replacement of fossil energy by new energy.
