Model testing beyond the scope of International Standards: an outlook.

The roles of hydropower plants within the energy system has been evolving during the last two decades. The potential to provide ancillary services to the grid is often harnessed, leading to a major change in hydropower plants operations. Ancillary services ...

The hydropower-Europe forum and the technology roadmap

Anton Schleiss

A new EU initiative, Hydropower-Europe, is reported here. This work, soon to be launched, will provide a framework for the hydropower sector in Europe to define a research and innovation agenda, and technology roadmap. The initiative is expected to help po ...

Four decades of hindsight into a complex hydropower system

Anton Schleiss, Pedro Filipe De Almeida Manso, Bettina Schaefli, José Pedro Gamito de Saldanha Calado Matos

Hydropower systems often operate in contextual conditions quite different from those for which they have been planned for. Often, the pace at which the changes occur does not invite operators to analyse their long-term effects and quantify the resilience o ...

Influencing the Bulk Power System Reserve by Dispatching Power Distribution Networks using Local Energy Storage

Mokhtar Bozorg

Multiple research works and power systems operational practices have qualitatively associated the progressive connection of stochastic renewable energy resources with the increase of power systems reserve requirements. At the same time, the price and techn ...

Hydropower Design under Uncertainties

Felix Oberrauch

The design of hydropower is determined by estimates and long-term forecasts. These forecasts and estimates are highly uncertain and make performance evaluation and design choices challenging. Performance evaluation of hydropower projects is affected by a n ...

Assessment of hydropower potential in wastewater systems and application to Switzerland

Anton Schleiss, Luca Rossi, Pedro Filipe De Almeida Manso, Philippe Heller, Irene Almeida Samora

Energy recovery through local hydropower generation is a way of coping with high electricity expenditures in wastewater systems (WWS). Installing small hydropower plants within WWS is already in some countries eligible for incentive policy mechanisms to re ...

Characterization of hydraulic behavior of orifices in conduits

Nicolas Jean François Pascal Ghislain Adam

High-head power plants are the main pillar of Swiss peak electricity production. With the 2050 Energy Strategy approved by Swiss voters, the annual production of hydroelectricity should increase by 4%, while 90% of the technically feasible potential is alr ...

Assessment of Power Swings in Hydropower Plants Through High-Order Modeling and Eigenanalysis

Christophe Nicolet, Basile Kawkabani, Pedro Camilo de Oliveira e Silva

POWER plants are subject to introduce disturbances in the power grid, resulting from interactions with the dynamical behavior of the energy source subsystem. In the case of hydropower plants when used to compensate for variations of power generation and co ...
