CFD-based analysis of pumped storage power plants implementing hydraulic short circuit operations
Elena Vagnoni, Alessandro Morabito
Hydraulic short circuit (HSC), corresponding to the simultaneous operation of the pumps and turbines, enhances the power flexibility of a pumped storage power plant (PSPP). However, comprehensive analyses are imperative to guarantee a secure and reliable o ...
Elsevier Sci Ltd2024A comprehensive review on geomembrane systems application in hydropower
Giovanni De Cesare, Samuel Luke Vorlet
Geomembrane systems have been used at hydropower plants as rehabilitation and mitigation technology for several decades and are now used worldwide. In the context of planning an energy transition that promotes the sustainable use of water resources for ene ...
2024Interlocking modular microfluidic cooling substrates for future high energy physics experiments
In high energy physics, semiconductor-based sensors are widely used in particle tracking applications. These sensors are typically glued on low-mass cooling substrates, which guarantee the correct thermal management and, at the same time, minimise their in ...
EPFL2023Structural impact of the start-up sequence on Pelton turbines lifetime: Analytical prediction and polynomial optimization
Mario Paolone, Elena Vagnoni, Aldo Leonardo Alerci
Hydropower plants play a crucial role in the power system facing ambitious renewable energy targets. Due to their inherent controllability, they are well suited to provide flexibility to the grid. However, an increased flexibility provision leads to a prol ...
2023Fiber pumps for wearable fluidic systems
Herbert Shea, Michael James Henry Smith, Vito Cacucciolo
Incorporating pressurized fluidic circuits into textiles can enable muscular support, thermoregulation, and haptic feedback in a convenient wearable form factor. However, conventional rigid pumps, with their associated noise and vibration, are unsuitable f ...
2023CFD simulations of hydraulic short-circuits in junctions, application to the Grand’Maison power plant
In the framework of the XFLEX HYDRO H2020 European Project, the pumped-storage power plant of Grand'Maison (France), owned by Electricité De France, focuses on the implementation of the hydraulic short-circuit (HSC) operating mode. This mode increases the ...
