A Study on Energy Storage system for Railway System

초록

There are two types of ESS. One is the wayside ESS. The other is the on-board ESS. In Korea, we developed and installed the wayside ESS on the track of Daejeon HRT in 2010. This paper presents how much energy is saved by the wayside ESS through the field test. The tests are focused on energy saving rate. Currently, we study the on-board ESS to save more energy. The simulation results of the on-board ESS on the same track of Daejeon HRT are presented.
