Development direction, technical issues, and key construction tasks for new power system

The implementation of green energy transformation, clean energy power replacement and supply, and the construction of the new power system are the primary driving forces for achieving strategic goals of carbon peak and carbon neutrality in China. The construction of the new power system is in a critical period of initiation and development, and it is necessary to clarify the direction of future development, clarify the current technical challenges and key technical issues, and determine the key technical tasks for the future. In this context, this study analyzes the development direction, technical issues, and key construction tasks of the new power system. Firstly, the development challenges of the new power system are analyzed from two aspects: the current situation of flexible regulation resources and the safety issues related to frequency and voltage. Secondly, the direction of technological innovation is analyzed from four aspects: the multiple power sources complementarity technology, power source and power grid collaborative technology, power supply and load interaction technology, and flexible and intelligent control technology. On this basis, three major technical issues are sorted out. Finally, the key construction tasks of the basic theory, flexible power generation, and collaborative control are detailed.
