Metro energy storage recycling case

How regenerative energy can be stored in a metro train?

If there is a high power demand from the low-voltage loads, regenerative energy produced by the metro train could be preferentially fed back to the AC 400 V grid to meet the demand. On the other hand, if the demand is low, the energy could be stored by a device such as a supercapacitor.

Why did Metro Trains Melbourne need an ESS system?

Metro Trains Melbourne required an ESS solution for a high-capacity, high-voltage environment. Credit: Pixabay. Technology company ABB ’s 1,500 Volt DC Enviline wayside energy storage system (ESS), a three-year project, captures braking energy and then returns it for the the acceleration of other trains which later use the same line section.

Can metrohess be reused?

Preliminary results confirm the feasibility of the energy saving concept indicating a large potential for the MetroHESS reuse of 5000–6000 kWh/day per rectifier substation of otherwise unused braking energy of a metro line and a subsequent s sizing of the stationary HESS is performed.

Can a hybrid regenerative braking energy recovery system stabilize Metro DC traction busbar voltage?

In order to fully utilize the regenerative braking energy of metro trains and stabilize the metro DC traction busbar voltage, a hybrid regenerative braking energy recovery system with a dual-mode power management strategy is proposed. Firstly, the construction of the hybrid regenerative braking energy recovery system is explained.

How does Metro Energy Management work?

Through this solution, Metro aimed to ensure customers have a smoother journey and increase frequency of trains on the line. This energy-management system is cost effective, in terms of land use and construction, and also reduced carbon emissions by 15%.

Does a stationary hybrid energy storage system work in Metro traction substations?

This paper focuses on the configuration of a stationary hybrid energy storage system, located in metro traction substations in turn located inside Metro stations. The recuperation energy of the metro braking phase is then reused to feed stationary electrical loads of metro stations.
