1. 1. Power-to-X-to-Power in Combined Cycle Power Plants : A Techno-Economic Feasibility Study

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Linus Engstam; [2021]
   Keywords : Power­to­X­to­power; Hydrogen; Ammonia; Combined cycle gas turbines; PEM electrolyzer; Technoeconomic analysis; Power­to­X­to­power; Vätgas; Ammoniak; Gasturbiner; PEM elektrolysator; Teknoekonomisk analys;

   Abstract : To support the large­scale integration of renewables in electricity grids, power­to­X­to­power (P2X2P) systems have been proposed. These systems serve to increase the flexibility of thermal power plants while potentially providing both economic and environmental benefits by allowing power from the plant to be redirected into an electrolyzer and converted to a gaseous energy carrier.

4. 3. Power Plant Operation Optimization Economic dispatch of combined cycle power plants

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Stefano Rosso; [2019]
   Keywords : ;

   Abstract : As electricity production from renewable sources increases, higher flexibility is required by fossil fuel generation to cope with the inherent fluctuations of solar and wind power. This results in shorter operating cycles and steeper ramps for the turbines, and more uncertainty for the operators. READ MORE

5. 4. Economic Dispatch of the Combined Cycle Power Plant Using Machine Learning

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Dhruv Bhatt; [2019]
