Hybrid Cyclicity: Combining The Benefits Of Cyclic And Non-Cyclic Timetables

Michel Bierlaire, Shadi Sharif Azadeh, Mohammad Yousef Maknoon, Tomas Robenek

We propose a new type of timetable that would combine both the regularity of the cyclic timetables and the flexibility of the non-cyclic ones. In order to do so, several combinations of the two timetables are considered. The regularity is incorporated in t ...

URANS Models for the Simulation of Full Load Pressure Surge in Francis Turbines Validated by Particle Image Velocimetry

François Avellan, Arthur Tristan Favrel

Due to the penetration of alternative renewable energies, the stabilization of the electrical power network relies on the off-design operation of turbines and pump-turbines in hydro-power plants. The occurrence of cavitation is however a common phenomenon ...

Assessing the potential increase of seasonal energy storage to mitigate the impact of climate change in Switzerland: Case study of the Grande Dixence dam

Anton Schleiss, Pedro Filipe De Almeida Manso, Jérôme François Sylvain Dujardin, Blaise Monay

The total storage capacity of the reservoirs in Switzerland represents only 42% of their annual production of electricity, but secures approximately 100% of hydropower’s contribution to the winter electricity supply. In order to avoid spilling, the storage ...

INFRASTRUCTURE – A CRUCIAL KEY FOR RESOURCE EFFICIENCY, SUSTAINABILITY AND RESILIENCE

Due to its significant contribution to socioeconomic development, its huge environmental impacts and its key role in a functioning economy, adequate infrastructure development is vital for our sustainable future. The way infrastructure such as roads, sewag ...

Pricing Electricity Through a Stochastic Non-Convex Market-Clearing Model

Farzaneh Abbaspourtorbati, Antonio J. Conejo

This paper proposes a pricing scheme for the day-ahead market in power systems with a large percentage of renewable stochastic production. To clear the day-ahead market, instead of a simplistic deterministic model, we use a two-stage stochastic programming ...

Prediction of Francis Turbine Prototype Part Load Pressure and Output Power Fluctuations with Hydroelectric Model

François Avellan, Christophe Nicolet, Christian Landry, Sébastien Alligné, Joao Gomes Pereira Junior, Antoine Béguin

The prediction of pressure and output power fluctuations amplitudes on Francis turbine prototype is a challenge for hydro-equipment industry since it is subjected to guarantees to ensure smooth and reliable operation of the hydro units. The European FP7 re ...

Conceptual design of the DEMO neutral beam injectors: main developments and R&D achievements

Ivo Furno, Minh Quang Tran

The objectives of the nuclear fusion power plant DEMO, to be built after the ITER experimental reactor, are usually understood to lie somewhere between those of ITER and a 'first of a kind' commercial plant. Hence, in DEMO the issues related to efficiency ...

Dynamics of the precessing vortex rope and its interaction with the system at Francis turbines part load operating conditions

François Avellan, Arthur Tristan Favrel, Christian Landry, Andres Müller, Keita Yamamoto, Joao Gomes Pereira Junior

At part load conditions, Francis turbines experience the formation of a cavitation vortex rope at the runner outlet whose precession acts as a pressure excitation source for the hydraulic circuit. This can lead to hydro-acoustic resonances characterized by ...

Caching of Bivariate Gaussians with Non-Uniform Preference Probabilities

Michael Christoph Gastpar, Guillaume Jean Op 't Veld

Caching is technique that alleviates networks during peak hours by transmitting partial information before a request for any is made. We study this method in a lossy source coding setting with Gaussian databases. A good caching strategy minimizes the data ...
