Abstract:
This paper attempts to assess the use of energy storage systems (ESS) for recovering and reusing braking energy in urban rail transportation systems from an economic point of view. Capital and maintenance costs are taken into account. The results suggest that a hybrid energy storage system using battery and ultracapacitor be an optimal mode both in terms of the economic considerations and the response time.
