Capacity Configuration in Integrated Energy Production Unit Considering Ladder-Type Carbon Trading Under CCER Quota

To enhance the efficiency of renewable energy and achieve low-carbon operations in energy systems, optimizing the capacity configuration of the Integrated Energy Production Unit (IEPU) and designing a sustainable economic operation strategy is essential. Referring to the Chinese Certified Emission Reduction (CCER)quota mechanism, this paper proposed a comprehensive configuration design for a ladder-type carbon trading model, incorporating CCER quotas and reward and punishment synergistic effects during the trading process. The optimized ladder-type carbon trading model is proposed by sharing a portion of the laddered carbon trading volume in CCER quotas. An optimal full life-cycle cost model is also introduced to better reflect the impact of different source device configurations on carbon emissions. Furthermore, a method for optimizing CCER carbon trading quotas and capacity configuration to identify the most sensitive segment of the ladder-type carbon trading parameters is presented to balance system economics and renewable energy consumption rates. The effectiveness of the proposed capacity configuration strategy is validated and compared by analyzing various scenarios.
