   On-board energy storage in DC systems  evaluated  
Modern energy storage devices permit the storage of braking energy on-board for use in subsequent acceleration phases. Especially in DC system, where energy losses in the distribution network are high, this could be an interesting alternative to feeding back energy into the supply system. Furthermore reduced peak load is beneficial for system capacity, voltage stability and energy costs.
Technology field: Regenerative braking and energy management
