Holm, S.R. (author)This thesis describes the derivation of an analytical model for the design and optimization of a permanent-magnet machine for use in an energy storage flywheel. A prototype of this flywheel is to be used as the peak-power unit in a hybrid electric city bus. The thesis starts by showing the feasibility of using a flywheel energy storage system...doctoral thesis 2003

Ummels, B.C. (author)Our society revolves around electricity. Most electricity is produced from fossil fuels, such as coal and natural gas. The disadvantages are that their supply is finite and unevenly distributed across the earth. Conventional power stations also emit greenhouse gases. Therefore, sustainable alternativees must be developed, such as wind power. The...doctoral thesis 2009

Baalbergen, F. (author), Bauer, P. (author), Ferreira, J.A. (author)Diesel generators in small electricity grids are mostly not used in a very efficient way. The reason for this is twofold. First of all, the efficiency of a diesel generator is dependent on the ratio determined by the average power divided by the peak power of the generator. The smaller this ratio is, the lower the efficiency. Furthermore, some...journal article 2009

Chappin, E.J.L. (author), Ferrero, M. (author), Lazzeroni, P. (author), Lukszo, Z. (author), Olivero, M. (author), Repetto, M. (author)This work presents a management procedure for hydroelectric facilities with daily storage. The water storage gives an additional degree of freedom allowing to shift in time power production when it is more convenient and to work at the maximum efficiency of hydraulic turbine. The management is optimized by coupling two different approaches:...conference paper 2012

Garcia-Tamayo, E. (author)The remarkable physicist Richard P. Feynman once said, more than fifty years ago: ”the principles of physics, as far as I can see, do not speak against the possibility of maneuvering things atom by atom. It is not an attempt to violate any laws; it is something, in principle, that can be done; but in practice, it has not been done because we are...doctoral thesis 2014

Anastasopol, A. (author)Reliable and affordable energy storage represents a bottleneck in a scenario where renewable energy sources become prominent on the energy market. With its high potential energy density and the natural abundance of the element, hydrogen gas is an attractive energy storage medium. But its gaseous nature, its high explosive potential and...doctoral thesis 2014

Bloemendal, Martin (author), Hartog, N (author)Aquifer thermal energy storage (ATES) is a technology to sustainably provide space heating and cooling. Particularly in The Netherlands the number of ATES systems has grown rapidly in the past decade, often with the (re)development of urban areas. To meet objectives for greenhouse gas emission reduction the number of ATES systems is expected and...conference paper 2016

Building climate energy management in smart thermal grids via aquifer thermal energy storage systemsRostampour, Vahab (author), Jaxa-Rozen, M. (author), Bloemendal, Martin (author), Keviczky, T. (author)This paper proposes a building energy management framework, described by mixed logical dynamical systems due to operating constraints and logic rules, together with an aquifer thermal energy storage (ATES) model. We develop a deterministic model predictive control strategy to meet building thermal energy demand. At each sampling a mixed...conference paper 2016
