Vigorously developing new energy is vital for China to achieve carbon peaking and carbon neutrality goals and to accelerate the green and low-carbon transformation of its energy structure.This study first investigates the current status and trend of China’s new energy development and then prospects grid integration scenarios for a high proportion of new energies in China in the medium(2030)and long term(2060).The challenges faced by the grid integration are analyzed,including coexistence of high-efficiency consumption and energy guarantee problems,increasing difficulty in safe and stable operation,and an unsuitable power market mechanism.Moreover,a key technology system is proposed from the perspectives of source side,grid side,load side,as well as energy storage and basic support.To achieve long-term steady development of the gird integration and operation for the high-proportioned new energy,we propose to strengthen coordinated planning to promote flexibility,make breakthroughs in key technologies,establish an interim mechanism between new energy policies and the power market,and improve the design of the power market to adapt to new energy consumption scenarios.This study could provide a basic reference for the research on power system planning and electric technologies.
