A study on energy storage system for Gold Line of LA Metro

Abstract

The ESS creates optimum conditions for energy regeneration in urban transit system. The ESS is able to store and discharge energy extremely quickly, consequently enabling a complete exchange of energy between vehicles, even if they are not braking and accelerating at precisely the same time, as is most frequently the case in everyday service. The ESS reduces primary energy consumption without affecting transport capacity and punctuality. The ESS is considered to be one of the useful devices for energy storing and recycling. This paper presents effects of energy saving and voltage stabilization by applying the energy storage system to Gold Line of LA Metro. The result indicates effect of the ESS. Application of the ESS and efficient use of regenerating energy cut CO2 emissions and affects environmental preservation.
