Production flexibility of small run-of-river power plants: KWGO smart-storage case study

Pedro Filipe De Almeida Manso, Vlad Hasmatuchi, Jessica Zordan, Matthieu Dreyer, Siamak Alimirzazadeh, Steve Crettenand

In the framework of the new Swiss feed-in-tariff system for Small Hydropower Plants (SHP), the aim of the SmallFLEX project, led by HES-SO Valais and performed in collaboration with EPFL, WSL, EAWAG, PVE and FMV, is to show how SHP can provide winter peak ...

Experimental and numerical investigations of a high-head pumped-storage power plant at speed no-load

François Avellan, Pedro Filipe De Almeida Manso, Cécile Münch-Alligné, Vlad Hasmatuchi

Due to the increasing integration of new renewable energies, the electrical grid undergoes more frequent instabilities. Hydroelectric power plants, particularly pumped storage plants, are well suited for grid control. However, this objective requires exten ...

Energy production with a tubular propeller turbine

Anton Schleiss, Cécile Münch-Alligné, Mário Jorge Rodrigues Pereira Da Franca, Vlad Hasmatuchi, Irene Almeida Samora

Micro-hydropower is a way of improving the energetic efficiency of existent water systems. In the particular case of drinking water systems, several studies have showed that pressure reducing valves can be by-passed with turbines in order to recover the di ...

Simulation of energy recovery on water utility networks by a micro-turbine with counter-rotating runners

François Avellan, Elena Vagnoni, Cécile Münch-Alligné, Loïc Andolfatto, Vlad Hasmatuchi

Wherever relief valves and other energy dissipation devices are installed to limit the pressure, water utility networks provide unexploited hydropower potentials. This is mainly due to a lack of economically viable technologies for energy recovery in the p ...

Non-intrusive detection of rotating stall in pump-turbines

Mohamed Farhat, Vlad Hasmatuchi, Steven Roth, Francisco Botero

When operated far from their optimum conditions, pump-turbines may exhibit strong hydrodynamic instabilities, often called rotating stall, which lead to substantial increase of vibration and risk of mechanical failure. In the present study, we have investi ...

Non-Linear Stability Analysis of a Reduced Scale Model Pump-Turbine at Off-Design Operation

François Avellan, Christian Landry, Andres Müller, Sébastien Alligné, Vlad Hasmatuchi, Steven Roth

Nowadays, the pump-storage power plants are a proven solution for storing electricity at large scale and offering flexibility to the power management. Therefore, the hydraulic machines are increasingly subject to off-design operation, start-up and shutdown ...
