Pelka, Sabine (author), De Vries, Laurens (author), Deissenroth, Marc (author)With an increasing wind and photovoltaic share, the German generation mix becomes more weather-dependent. Backup technologies can help to bridge scarcity moments. These rare moments with high prices are the main events for their cost recovery. However, the uncertain revenue flow combined with long payback periods leads to high investment...conference paper 2019

Bandyopadhyay, S. (author), Chandra Mouli, G.R. (author), Qin, Z. (author), Ramirez Elizondo, L.M. (author), Bauer, P. (author)Microgrid with integrated photo-voltaics (PV) and battery storage system (BSS) is a promising technology for future residential applications. Optimally sizing the PV system and BSS can maximise self-sufficiency, grid relief, and at the same time can be cost-effective by exploiting tariff incentives. To that end, this paper presents a...journal article 2019

Urso, A. (author), Giagka, Vasiliki (author), Serdijn, W.A. (author)This manuscript points out some mistakes in the Introduction and in the table of comparison of a paper already published in this journal by Hsu and Schmid [1]. Although the main claim of [1] is still preserved, we believe the paper needs to be rectified for scientific correctness of the work. In [1], the first High Frequency Switched...journal article 2019

Grazioli, D. (author), Verners, O. (author), Zadin, Vahur (author), Brandell, Daniel (author), Simone, A. (author)We analyze the effects of mechanical stresses arising in a solid polymer electrolyte (SPE) on the electrochemical performance of the electrolyte component of a lithium ion battery. The SPE is modeled with a coupled ionic conduction-deformation model that allows to investigate the effect of mechanical stresses induced by the redistribution of...journal article 2019
