摘要：
Carbon capture technology is essential to achieve the goal of carbon peak and carbon neutrality in the generation industry. When the traditional carbon capture plants (CCP) participate in renewable energy consumption under flexible operation mode, they will lose a certain carbon capture intensity and cannot flexibly absorb renewable energy under deep decarburization conditions. To this end, this paper first proposes a carbon capture-energy storage system (CC-ESS) for CCP and renewable energy sources. The primary energy storage system (ESS) is used for renewable energy consumption. The secondary ESS assists carbon capture units in achieving electricity-carbon decoupling. The transient and dynamic electricity-carbon decoupling characteristics are analyzed. Under the framework, the uncertainty of wind and solar output is portrayed based on KL divergence, and the distributionally robust optimization of energy storage capacity sizing is established. Finally, the simulation verification is carried out through the case study. The results prove the effectiveness of the energy storage capacity sizing model. The proposed CC-ESS can improve the consumption level of renewable energy and ensure high carbon capture intensity. ©2023 Chin.Soc.for Elec.Eng.
