van der Horst, Koen (author), Diab, I. (author), Chandra Mouli, G.R. (author), Bauer, P. (author)The traction substations of urban electric transport grids are oversized and underutilized in terms of their capacity. While their over-sizing is an unfortunate waste, their under-utilization creates the major hurdle for the integration of renewables into these grids due to the lack of a base load. Therefore, integrating smart grid loads such...journal article 2023

Diab, I. (author), Saffirio, Alice (author), Chandra Mouli, G.R. (author), Bauer, P. (author)Solar PV systems have so far been the source of choice for the sustainable supply of urban electric transport networks—like trams and trolleybus grids. However, no consensus exists yet on the placement or sizing of PV systems at the traction substations, and no method is available for easy estimation of the PV system utilization performance....journal article 2023

Diab, I. (author), Eggermont, Rik (author), Chandra Mouli, G.R. (author), Bauer, P. (author)The decarbonization of urban bus fleets can be made by their electrification as in-motion-charging (IMC) buses which can run as trolleybuses or in battery mode. The benefit is that IMC buses can use the existing trolleygrid infrastructure where their route overlaps with it to charge the battery and operate in battery mode outside of it....journal article 2023

Vermeer, W.W.M. (author), Chandra Mouli, G.R. (author), Bauer, P. (author)Battery aging is one of the critical problems to be tackled in battery research, as it limits the power and energy capacity during the battery's life. Therefore, optimizing the design of battery systems requires a good understanding of aging behavior. Due to their simplicity, empirical and semiempirical models (EMs) are frequently used in...journal article 2022

Rituraj, G. (author), Chandra Mouli, G.R. (author), Bauer, P. (author)In recent years, the research interest in off-grid (standalone mode) and hybrid (capable of both standalone and grid-connected modes) charging systems for electric vehicles (EVs) has increased. The main reason is to provide a seamless charging infrastructure in urban and rural areas where the electrical grid is unreliable or unavailable so that...journal article 2022
