On 19 May the Erasmus Energy Forum 2016 took place in Rotterdam. At this event, researchers of the Faculty of EEMCS won the Erasmus Energy Science Award (the best paper) and the Best Poster Prize.

Winner 2016 Science Award

The Erasmus Energy Science Award 2016 went to EEMCS-researchers: Rens Philipsen, German Morales-Espana, Mathijs de Weerdt and Laurens de Vries. They won this award with their paper and presentation: Imperfect Unit Commitment Decisions with Perfect Information: a Real-time Comparison of Energy versus Power.

Best Poster Prize

PhD students Gautham Ram Chandra Mouli and Venugopal Prasanth presented their combined work on “Charging of EV from PV and Contactless Power” at the Erasmus Energy Forum. Their poster presentation won the Best Poster Prize in this event (1/10), with an overwhelming majority of the people voting for this poster (> 50%). The poster presented, detailed the research carried out at the DCE&S group in the areas of PV integration and Contactless Inductive Power Transfer (IPT).

In order to cope with fluctuations and uncertainty, power systems rely on contracted reserves. The day-ahead Unit Commitment (UC) is the short-term planning process which is commonly used to schedule these resources at minimum cost, while operating the system and units within secure technical limits. This paper shows through the evaluation of deterministic cases that conventional energy-based UC formulations lead to inefficient use of reserves in real-time operation to deal with completely known deterministic events. These inefficient decisions are inherent to the assumptions underlying the energy-based formulation, and the misaligned incentives between markets and real-time operation. Economic efficiency and system security can be improved by adopting a UC formulation which explicitly considers the instantaneous power trajectories of generators.

The poster Charging of EV from PV and Contactless Power, detailed the research carried out at the DCE&S group in the areas of PV integration and Contactless Inductive Power Transfer (IPT). The highlights were the development of 3-port converter that integrates PV, grid and EVs from a single dc link.  This study is specifically focused on a smart charging station of a car port with 10 KW PV panels, producing a net solar yield of 24 kW for 55% of an year. This technology is co-developed by TU Delft, PRE and ABB. The technology of IPT for EVs is being researched at DCE&S for more than 5 years. Several aspects such as coil shape design, misalignment tolerance, electromagnetic design, high efficiency power converters for processing 85 kHz ac power and reactive power compensation are considered in the research. A bi-directional converter for an on-board EV charging by IPT that achieved >91% with SiC switches with an air-gap of 5 cms was presented. The vision of integration of these technologies is that, it will be possible to design a solar charging car port with EVs being charged both wired and wireless in the future. To aid this vision, a 4-port converter (upgraded with a wireless option), all with a single dc grid that can enable both V2G and G2V options begs development. Together all these technologies are expected to disrupt the e-mobility and renewable energy segments and we are at the fore-front of this research.
