6 FAQs about [Metro electric energy storage]
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.
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.
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 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 much energy does a battery-powered metro system produce a year?
When the swappable battery-powered metro system is transformed to net-zero concept balancing through the 1907 MWh of electricity derived annually from its renewable energy by the combination of 957.4 MWh from solar energy and 950 MWh from wind energy, the system annually imports 505.3 MWh from and exports 776.8 MWh to the utility grid.
Does energy flexibility matter in battery-based Metro Railways?
In overall, the improvement in the various objectives of leveraging energy flexibility in the battery-based metro railway system is relatively compared with itself, the same one with no energy flexibility strategies. Therefore, this consideration does not impact the primary goals and the deliveries of the research.
