Talk Title: New Dry-Gravitational Energy Storage - Challenges and Compromises to the Design of the Power Management System
New dry-gravitational energy storage facilities have been proposed recently as high power systems (EnergyVault, energyvault.com) or using the vertical shafts of abandoned mines. The main arguments are at the characteristic of high number of possible cycles and low aging phenomena like in pumped hydro plants, but with higher density materials..
Their size and properties are analysed, together with their specific problematics rated to the kinetic energy component (the “dry waterhammer”)
An innovative solution is proposed where the kinetic energy is absorbed by a bank of supercapacitors, avoiding a surge in the power exchanged with the grid.
The design of the supercapacitors is is very special, due to the high-power level of the exchange, leading to an oversize of the energy capacity.
A short introduction to Prof.Rufer Alfred: Alfred Rufer received a Master's degree from the Swiss Federal Institute of Technology in Lausanne (EPFL), Switzerland, in 1976.
From 1976 to 1978, he was a research assistant with EPFL’s Chair of Industrial Electronics (Prof. H. Bühler).
In 1978, Alfred Rufer joined ABB, Turgi, Switzerland, where he worked in the fields of power electronics and control for high-power variable frequency converters for drives.
A Rufer has participated in several development teams on new applications of power electronics, like renewable energies. In 1985, he was a Group Leader for power electronics development at ABB.
1993 he became an Assistant Professor at EPFL. Since 1996, he was elected as a Full Professor and Head of the Industrial Electronics Laboratory at EPFL.
The Industrial Electronics Lab (LEI) is active in power electronics used in energy conversion and energy storage, in modelling and simulation of systems, including control strategies and control circuits.
Alfred Rufer has several patents and is the author of publications on power electronics and applications.
In the year 2006, A. Rufer was elected at the IEEE Fellow grade.
From March 1st 2016 Alfred Rufer is retired, and gets the title of Professor Emeritus

Talk Title: Electrical Power Systems and Energy Conversion for Transportation Electrification
The keynote presentation will consider the importance of the role of electrical power system design/control and energy conversions systems in the ever increasing rush for Transportation Electrification. These are key technologies to the success of lower carbon transportation in the future, so there is a need to understand and excel in the technological development needed for these applications. This presentation will look at some of these technology advances, the challenges and opportunities for our research areas as well as giving examples from the electrification of aircraft, cars and superbikes.
A short introduction to Prof Pat Wheeler:
Prof Pat Wheeler received his BEng [Hons] degree in 1990 from the University of Bristol, UK.
