Flywheel vs. Supercapacitor as Wayside Energy Storage for Electric Rail Transit
Different ESS technologies have been proposed and implemented in rail transit systems worldwide. For instance, a flywheel was installed in the Los Angeles Metro for energy saving, and a supercapacitor was installed in several European countries for energy saving and voltage regulation [3]. A sodium-sulfur (NA-s) battery was used in the
