Energy-efficient urban rail systems: strategies for an optimal management of regenerative braking energy

Urban rail plays a key role in the sustainable development of metropolitan areas for several reasons such as its high capacity, energy efficiency and lack of local air pollution. However, in order to address the increasing capacity demand and rising energy costs, while maintaining/enhancing its service quality, considerable energy efficiency improvements must be achieved. The recovery and reuse of braking energy is one of the most promising measures to reduce urban rail energy consumption, on account of the numerous and frequent stops involved. This paper provides a comprehensive assessment and comparison of the solutions currently available for the recovery and optimal management of regenerative braking energy in urban rail. It discusses different strategies to increase the interchange of regenerated energy between trains, analyses the main features of both on-board and stationary energy storage systems, and evaluates reversible substations as a means to return the surplus regenerated energy into the upstream distribution network.
