Review of Regenerative Braking Energy Storage and Utilization

Due to the short distance between urban rail transit stations, a large amount of regenerative electric energy will be generated. Studying how to recuperate regenerative braking energy and control the voltage fluctuation of the traction network within allowable range can result in economic as well as environmental merits, which has important practical significance in

Energetic optimization of regenerative braking for high speed

On the other hand, the mean power W rmean that can be regenerated depends on the kinetic energy of the train m i x ̇ max 2 and on the braking occurrence f b (i.e. defined as the number of braking events with respect to traveling time). On tramways and light urban railways, the vehicles traveling speed and equivalent inertia are much smaller with respect to
