6 FAQs about [Metro energy storage system design unit]

What are the different types of Energy Management in Metro stations?

The three main categories in energy management in metro stations are the energy efficiency system, renewable energy system and recovery energy system.

What is energy storage?

Energy stored used on Metro station electrical loads e.g. lighting/ventilation/pumps/etc. or for other public uses (e.g. street lighting). Field measurements based energy storage system design with proven feasibility.

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.

What are the benefits of storing energy in Metro stations?

In turn the stored energy could power upon demand selected stationary electrical loads in Metro stations of a non-safety critical character (such as lighting, ventilation, pumps, etc.) leading to very significant energy savings and to a corresponding reduction of greenhouse gases.

How much energy does a metro station use?

A typical Athens Metro station stationary electrical loads consumption has been experimentally measured to be of the order of 2000 kWh/day hence the HESS energy could cover most of these loads, as long as they are not of a safety critical nature (e.g. tunnel ventilation).

What is the energy management status of a metro station?

If the relative weight of a metro station is in the range of 50% to 70%, they have a developing energy management status, and if the relative weight is between 70% and 90%, the energy management status is acceptable. Lastly, if the relative weight of a metro station is 90% to 100%, the energy management has an excellent status.
