Initial Evaluation of Carbon Capture Plant Flexibility

摘要

Fossil fuel generating capacity is currently run at variable load in many power systems to achieve instantaneous demand/supply matching and provide reserve capacity. This paper discusses changes to the flexibility of fossil-fired power stations as a result of adding carbon capture and suggests that these changes could be analysed effectively using a grid simulation technique to identify changes to the cost of secure and reliable electricity generation. The modelling presented here focuses on describing and analysing various modes of operation for post-combustion capture plants. Other capture technologies may also alter plant flexibility and some specific examples are highlighted.
