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

Diab, I. (author), Chandra Mouli, G.R. (author), Bauer, P. (author)A typical approach to harvesting the excess braking energy of a railway car has been to use a storage system. However, research momentum has been growing in the direction of integrating smart loads like EV chargers into traction networks, and this can offer a more efficient and economical solution to the harvesting of braking energy. This paper...conference paper 2023

Diab, I. (author), Chandra Mouli, G.R. (author), Bauer, P. (author)When the braking energy in electric transportation grids is not met by another vehicle's demand, it is either harvested by storage systems or wasted in braking resistors. This paper looks at three methods for increasing the amount of harvested braking energy without the use of expensive storage systems: decreasing the substation voltage,...conference paper 2023

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

Damianakis, Nikolaos (author), Chandra Mouli, G.R. (author), Bauer, P. (author)An important aspect of the energy transition is the expected grid impact due to the abrupt increase of distributed electric generation and electric load demand. A part of this impact is going to be inflicted by the electrification of heating with heat pumps (HPs). Therefore, it is essential that the future power consumption of electric...conference paper 2023
