Targeted Traction Power Modulation of High-Speed Trains for Stabilization of Electric Supply Network with the Electric Flexibility

SNCF is the largest electricity consumer in France. The rolling stock has the highest share of France railway system electricity consumption at 84%. The traction power of High-Speed Trains (HST) can reach up to 50% of the total rolling stock electricity consumption during the rush hours of weekdays. Given the new policies regarding energy regulation in peak power demand periods, load modulation by the traction power of HST is one of the flexibilities that are investigated by SNCF in the Smart Grid project. This paper presents the study related to the feasibility of a Targeted Traction Power Modulation (TTPM) of HST. Experimental tests have been achieved as proof of concept on the SNCF South-Europe-Atlantic HS line. Experimentation results showed between 20 and 30% of energy savings during the peak power demand period.
