Rational sizing of onboard EDLC and placement of charging facilities for a LRT system with intermittent power supply

Abstract

The optimal operation of catenary free Light Rail Transit (LRT) with onboard energy storage device minimizing energy consumption is discussed in this paper. The Electric Double Layer Capacitor (EDLC) is assumed as an energy storage device because of its high power density, long lifetime and quick charge/discharge. The proposed method can determine the optimal capacitance of the EDLC and placement of charging facility at different cases for the purpose of saving the energy consumption. The trend of the optimal design of the EDLC sizing and the charging facility placement is finally discussed qualitatively.
