Abstract

The continuous expansion of renewable energy installations has resulted in the emergence of integrated energy bases, which couple renewable power generation with conventional thermal units. These bases have experienced rapid development and have gradually become key participants in electricity and carbon markets. The behavior of these entities in terms of decision-making exerts a simultaneous influence on the clearing results of both markets. In this context, an analysis of actual operating conditions at integrated energy bases reveals that the carbon emission intensity of thermal units exhibits fluctuations tied to unit load factors. The carbon emission fluctuation characteristics of thermal power units exhibit distinct differences across different stages of power generation. This characteristic exerts a significant influence on the decision-making behavior of thermal power units engaged in the electricity and carbon markets. It is evident that a carbon-electricity coordinated decision-making model for integrated energy bases with combined renewable-thermal operation, considering the dynamic carbon emission characteristics of thermal power units, has been established. Utilizing an enhanced IEEE-5 node as a test case, the efficacy of the proposed method is substantiated.
