Identifying operational requirements for flexible CCS plant in future energy systems

Abstract

This paper aims at a discussion of operational requirements for thermal power plants with carbon capture and storage in terms of their interaction with the power system, in regions with high penetration of variable renewable energy sources. Market opportunities for flexible power plants equipped with carbon capture processes have been discussed. These opportunities comprise day-ahead markets, intraday markets, balancing markets and providing ancillary services for stable operation of the power grid. In addition, technical requirements for power units to provide ancillary services and bidding in different balancing markets in four different power areas in EU have been identified. The identified technical requirements can be used to define scenarios for operational flexibility studies based on dynamic process simulation of thermal power plants with CO2 capture.
