Abstract

The core objective of the third global energy transition is to promote the formation of a low-carbon energy system based on renewable energy, and the low-carbon transformation of the electric power system is a key part of this process. To achieve the goal of “double carbon” and promote the transformation of regional energy resources structure, the mechanism of the impact of the low-carbon energy transition on the optimization of power supply structure is analyzed, and a model for measuring the marginal contribution of power supply is established. On this basis, a provincial power structure optimization model is constructed under the low-carbon energy transition taking into account the marginal contribution, and the model is solved by a genetic algorithm, and finally the validity of the model is verified by empirical research. The results show that a high proportion of new energy access is the key to realizing the decarbonization of power structure under the premise of ensuring the stability of power supply; the optimization model taking into account the marginal contribution can effectively guide the reasonableness of power supply planning, and seek for power supply solutions under the double benefit of economy and environment.
