I have a thesis on Utilize the electrical power from Regenerative Braking in 750 Vdc Traction by simulation in the Program MATLAB Simulink. I made the Power Load flow from 24kV to Traction Transformer and Rectifier to supply 750 Vcd but how to do it next on the supply regenerative power back in the source which to be up the voltage to 840 Vdc in the simulation.
