   Sammanfattning : Efforts to mitigate climate change and current geopolitical disruptions have revealed that changes to the existing energy system are urgently required to offer sustainable and secure energy for Europe. Hence, the role of conventional thermal power plants is being challenged and new technologies providing additional functionality for the power grid are pushing into the market. LÄS MER

3. 2. 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.

4. 3. Techno-Economic Analysis of an Innovative Purely Solar Driven Combined Cycle System based on Packed Bed TES Technology

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

   Författare :Tianqi Ruan; [2019]
   Nyckelord :Tower CSP Techno-economic analysis; Dynamic simulation; Tower CSP teknisk-ekonomisk analys; Dynamisk simulering;

   Sammanfattning : With increasing awareness of environmental issues and worldwide requirements for sustainable development, renewable energy technologies with lower environmental impact, especially those having abundant resources like wind and solar energy, attract more attention. Concentrating Solar Power (CSP) is one of the most promising solar energy technologies. LÄS MER

5. 4. 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

7. 5. Derivation of a correlation to determine a combined cycle's performance based on data from the gas turbine exhaust

   Master-uppsats, Lunds universitet/Institutionen för energivetenskaper
