Abstract: Building a clean low-carbon energy dominated energy supply system and forming a new-type power system is the key to achieving the target of carbon neutrality. Transiting from a fossil-fuel-dominated system to a clean-energy- dominated system, the power system faces multiple challenges and evolution including new power balance mechanisms, complex security problems, and cost allocation principles. The connotation and features of the new-type power system were revealed from the aspects including structure, morphology, technology and mechanism. The evolution path of new-type power system was also analyzed. Finally, the development suggestions and prospects for the construction of new-type power system were put forward.
