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.

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 Sande, Robin (author), Deshmukh, R.S. (author), Shekhar, A. (author), Bauer, P. (author)When operating a modular multilevel converter (MMC), a margin appears between the arm voltage and sum capacitor voltage corresponding to the power dependent ripple. This margin can be used to enhance the DC link voltage and increase the transfer capacity of an MMC-based distribution link while keeping the submodule (SM) stresses fixed....conference paper 2023
