2. 1. Low head pumped hydro storage with contra-rotating pump-turbines

   Author : Jonathan Fahlbeck; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy storage; Pumped hydro storage; CFD; Transients; Pump-turbine; Low head; OpenFOAM; Contra-rotating; Hydropower;

   Abstract : The increasing share of electrical energy production by intermittent sources pushes the demand for energy storage. Pumped hydro storage (PHS) has a long history of providing a cost-efficient energy storage solution. However, for PHS to be a viable option, a large head is typically required. READ MORE

4. 2. Wind power in thermal power systems

   Author : Lisa Göransson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; integration; wind power; variation moderator; PHEV; storage;

   Abstract : AbstractWind power is a key technology in the effort to transform the power system in order to reduce its climate impact. However, the ability of wind power to reduce CO2-emissions depends on the properties of the power system. READ MORE
