Does CCS reduce power generation flexibility? A dynamic study of combined cycles with post-combustion CO2 capture
Rúa, Jairo; Bui, Mai; Nord, Lars O.; Mac Dowell, Niall (Journal article; Peer reviewed, 2020)To date, the deployment, integration, and utilization of intermittent renewable energy sources, such as wind and solar power, in the global energy system has been the cornerstone of efforts to combat climate change. At the ... -
Exergy Analysis for Combined Heat and Power (CHP) Plants
Rúa, Jairo; Nord, Lars O. (Chapter, 2018)Combined heat and power plants are an efficient technology for waste heat recovery applications where both heat and power are demanded. Steam Rankine cycles are normally utilized when high temperature exhaust streams are ... -
Model predictive control for combined cycles integrated with CO2 capture plants
Rúa, Jairo; Nord, Lars O.; Hillestad, Magne (Peer reviewed; Journal article, 2021)Flexible thermal power plants integrated with CO2 capture systems can balance the intermittent power generation of renewable energy sources with low-carbon electricity. Among these power systems, natural gas combined cycles ... -
Optimal control of flexible natural gas combined cycles with stress monitoring: Linear vs nonlinear model predictive control
Rúa, Jairo; Nord, Lars O. (Peer reviewed; Journal article, 2020)In future energy markets, traditional thermal power plants are expected to cycle more to adapt their operation to the intermittent power generation of renewable energy sources. Gas turbine load ramps and stresses in ... -
Optimal dynamic operation of natural gas combined cycles accounting for stresses in thick-walled components
Rúa, Jairo; Nord, Lars O.; Agromayor, Roberto; Hillestad, Magne (Journal article; Peer reviewed, 2020)Flexible natural gas combined cycles will play a fundamental role in future electric markets.Stressesinthick-walled components and gasturbine load ramps are arguably the main limiting factors during transient operation.Classical ... -
Optimal scheduling of flexible thermal power plants with lifetime enhancement under uncertainty
Rúa, Jairo; Verheyleweghen, Adriaen; Jäschke, Johannes; Nord, Lars O. (Peer reviewed; Journal article, 2021)Renewable energy sources have been the focal point to decarbonise the power sector. The large deployment of these intermittent power generation units requires mechanisms to balance the grid. Thermal power plants can provide ...
