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

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

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

   Sammanfattning : 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.

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :RAFAEL DE LEON; [2021]
   Nyckelord :Variable renewable energy sources; Supply-demand balance; Load factor; Production; Prices signals; Loss of load duration LOLD ; Margin; Nuclear power flexibility; Optimization; Variabla förnybara energikällor; balans mellan utbud och efterfrågan; belastningsfaktor; produktion; prissignaler; förlust av lasttid LOLD ; marginal; kärnkraftsflexibilitet; optimering;

   Sammanfattning : France is planning a strong development of solar photovoltaics (PV) and wind power in the medium term disrupting the power system. This Master Thesis analyzes the impacts of variable renewable energy production on the supply-demand balance from 2021 to 2025 in France. The model used relies on a dynamic programming method.

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

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Stefano Rosso; [2019]
   Nyckelord :;

   Sammanfattning : 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. LÄS MER

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

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)
