How can energy storage be used in a traction power system?
Energy storage can be used to store energy that would otherwise have been consumed by the resistor banks, and then released back into the traction power system when there is sufficient electrical load. If all resistor energy could be recovered using ESS the total annual savings for the 7 Line would be 6,335,164 kWh or about $886,923.
