DynStart - Start-up and Transient Behaviour of Power Plants

The joined research project "DYNSTART: Start-Up and Transient Behaviour of Power Plants" investigated the capabilities of power plants with and without CCS technologies to provide residual loads in future energy markets. The study points out potentials and limits of operation at extra-low-load and during start-up and shut-down. Besides the process-technical aspects of the issue modern MIMO control strategies are focused in the study as can improve the power plants' abilities to fulfil future grid requirements.

The Modelica library ClaRa

The Modelica library ClaRa was improved during the research project. ClaRa stands for Clausius-Rankine cycle. The source code of the library was completed by new components and improved with respect to its numerical robustness and validity in special operation modes (start-up, shut down, downtime).
