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
