Frontiers of (Pareto) Optimal and Sustainable Water Management for Hydropower and Ecology

David Andrew Barry, Paolo Perona, Amin Niayifar, Pierre Razurel

River regulation alters the natural flow regime of streams with consequent impacts on terrestrial and aquatic habitats of the riparian zone. The severity of such impacts can be modulated by changing the redistribution rules at water intakes and reservoirs. ...

The Potential of Vehicle-to-Grid to Support the Energy Transition: A Case Study on Switzerland

Loris Di Natale

Energy systems are undergoing a profound transition worldwide, substituting nuclear and thermal power with intermittent renewable energy sources (RES), creating discrepancies between the production and consumption of electricity and increasing their depend ...

Assessing the energy potential of modernizing the European hydropower fleet

Anton Schleiss, Elena Vagnoni

About 50% of all hydropower plants (HPPs) worldwide were originally commissioned more than 40 years ago, so that the advanced age of the fleet is a major concern across all continents, and especially in Europe. The modernization of HPPs can generate severa ...

Swiss Potential for Hydropower Generation and Storage - Synthesis report

François Avellan, Pedro Filipe De Almeida Manso, Paolo Burlando

Hydropower (HP) is the backbone of the Swiss electricity system providing around 60 % (36 TWh/a) of the total electricity generated on a yearly average. With the planned phase-out of nuclear power plants, HP and other Renewable Energy Sources (RES) will ne ...

Heightening of Very High Gravity Dams: The Case Study of the Grande Dixence

Giovanni De Cesare, Pedro Filipe De Almeida Manso

Heightening very high gravity dams is one of the solutions considered as part of the energy transition and to mitigate the effects of climate change. The paper presents a stepwise approach to assess the potential for dam heightening and its impact on the h ...

Numerical Simulations of an Innovative Water Stirring Device for Fine Sediment Release: The Case Study of the Future Trift Reservoir

Pedro Filipe De Almeida Manso, Azin Amini

Reservoir sedimentation and consequently lack of storage volume and perturbation of the operation of intakes and bottom outlet is a key challenge affecting both hydropower production as well as dam safety and flood management. In the framework of a peer-re ...

Design and Control of a KE (Kinetic Energy) - Compensated Gravitational Energy Storage System

Alfred Rufer

A gravitational energy storage device is described where the kinetic energy to recover while braking a vertically moving mass is compensated by an auxiliary storage device based on supercapacitors. The characteristic power surge occurring by a fast decreas ...
