On a Low-Carbon Thermal Energy Power Planning Model Based on Green Certificate Allocation Mechanism

In view of the problems such as high carbon emissions and low return on investment in conventional power planning, this paper proposed a low-carbon thermal energy power planning model based on a green certificate allocation mechanism. First, considering the uneven distribution of power generation resources in the power sector and the significant differences in power generation technologies in various regions of China, a green certificate allocation mechanism was established based on regional comparison to ensure a fair allocation of carbon quotas; then, based on the idea of full life cycle, an in-depth and comprehensive analysis was conducted on the low-carbon thermal energy power technologies, and a new low-carbon thermal energy power planning mode was established; on this basis, with investment costs, operation and maintenance costs, power generation costs and low-carbon benefits as the objective functions, a low-carbon power planning model with the maximum net benefit was established; after that, the proposed low-carbon thermal energy power planning model was optimized and solved with the discrete bacterial colony chemotaxis algorithm, and the results were compared with the optimized results of conventional power planning, and the roles of various low-carbon power elements in different low-carbon scenarios were analyzed. The results of the example analysis show that the proposed model can effectively reduce the carbon emissions of the power sector and increase the power generation benefits of the units, so it will provide a useful reference for the low-carbon power planning work in the future.
