Metro battery 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.

How will a 100MW battery energy storage system work?

The facility will serve as a large-scale battery energy storage system capable of charging from, and discharging into, the New York power grid. When fully functional, the 100MW battery energy storage project will be able to discharge electricity to the grid particularly during peak demand.

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).

How many kWh a day can a power station save?

Depending on the desired value of energy savings, it appears that storage savings of up to 1900 kWh/day are possible for the said station, corresponding to 100 % of its measured daily energy demand .

Can a stationary super-capacitor save regenerative braking energy in a metro line?
