Erevan tram energy storage

Can EVs be used for energy storage in a tram network?

Using EVs for energy storage to the tram network could be more advantageous on the economic feasibility than the stationary ESS, but work is still ongoing in this area. The work presented can be generalised to any tram network through the adoption of the processes outlined in the paper for the specific network.

Does the ESS provide its own energy to the tram?

Conversely, if the increase of E reg is less than the reduction of energy from E sub, then the ESS provides its own energy to the tram.

Could EV battery be used as ESS for the tram network?

However, exploiting an EV battery as the ESS for the tram network is expected to contribute additional operating cycles to the EV battery which could potentially degrade the battery life quicker than seen in normal EV use.

How does the number of tramcars affect the energy balance?

Therefore, some tram line sections will have tramcars from one single route travelling in it, and some tram line sections will have tramcars from multiple routes travelling over it. The number of tramcars travelling on the tracks directly impacts the energy balance of the given tram line section.

Can ESS save energy in the Supertram network?

The introduction of ESS can effectively deliver an energy-saving to the Supertram network, however the costs of the systems have not been addressed. Thus an economic evaluation has been conducted on ESS installations with different capacities and number of installations.

How does the energy storage system work?

Additionally, with this initial condition, the ESS has the capacity to either store excess energy, or supply energy to the tram system over the course of the day, this being reflected in the final state of charge of the ESS at the end of the days operation.
