Optimization Study on the Comprehensive Benefits of Straw Biogas Power Plants Participating in Electricity-Carbon Coupled Trading Based on Dual-Carbon Background

With the goal of "carbon peaking and carbon neutrality", China has accelerated the development of biomass energy, and straw biogas power generation, as a clean energy technology for converting agricultural waste, which has significant environmental and economic value. As a new energy generation enterprise, straw biogas power generation enterprises can gain profits from both the electricity market and the carbon market at the same time. This paper establishes a model for maximizing the daily operating revenue of straw power plant participating in the coupled electricity-carbon trading market by considering the revenue, cost, and relevant constraints of the power plant, then applies the model to practical cases to obtain the maximum daily operating revenue of the power plant of 90.16 yuan, and finally conducts a sensitivity analysis of the results to draw the relevant conclusions about the optimization of the economic benefits of straw biogas power plant.
