6 FAQs about [Metro energy storage power station]
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 a hybrid energy storage system?
A hybrid Energy Storage System termed MetroHESS foresees the storage and reuse of regenerative train braking energy through an active combination of batteries covering base power electrical consumer loads in Metro stations and supercapacitors able to receive the energy power peaks from train braking.
Why is energy storage important for traction power substations?
The energy storage unit charges during peaks and discharges during sags, keeping the voltage within operating tolerances. This can help protect other systems from damage. It can also supplement low voltage on the traction power at a fraction of the cost of adding new traction power substations.
