Power Management for a DC MicroGrid in a Smart Railway Station including Recovery Braking

A power management controller able to provide optimal reference values to local controllers for a DC microgrid recycling the train braking energy in a railway station is introduced. Power balance and desired energy levels are the targets of the proposed controller. Constraints regarding the nature of the devices or the physics of the grid are considered. Simulation results illustrating two different cases with their respective optimal control actions are provided.
