Abstract:

Building a new-type power system dominated by new energy sources is a critical pathway towards achieving China's "Dual Carbon" strategic goals. Since the inception of the "14th Five-Year Plan" period, China's power system has undergone profound transformations in its generation mix, grid configuration, and technological foundation, making the enhancement of power supply-demand synergy capability under these new circumstances an urgent imperative. Focusing on the new-type power system, this study firstly defines the fundamental concept and connotation of the supply-demand synergy and systematically identifies the critical scenarios that require enhanced synergy. Then, the study conducts an in-depth analysis of all the factors influencing supply-demand synergy and their underlying mechanisms from perspective such as policy, market, technology, etc. Finally, on the basis of an in-depth deconstruction from multiple perspectives such as space, time, resource, and form, this study innovatively constructs a theoretical framework model for the synergy of supply-demand across all factor to provide a solid theoretical foundation for the innovative upgrading of the new-type power system, and to contribute to the effective planning of its high-quality development blueprintt.

Key words: carbon emission peak and carbon neutrality, renewable energy, supply-demand synergy, all-factor, new-type power system
