Solution to the new energy battery problem in communication network cabinets

Why are batteries used in telecommunications networks?

Batteries are classically used as backup in case of power outages in telecommunications networks to keep the services always active. Recently, network operators use the batteries as a demand response lever, so as to reduce the energy costs and to generate revenues in the energy market.

Can a telecommunications operator optimize the use of a battery?

In this work, we study how the telecommunications operator can optimize the use of a battery over a given horizon to reduce energy costs and to perform load curtailments efficiently, as long as the safety usage rules are respected.

Are graph-oriented battery management policies effective?

Finally, simulations based on real data from the French telecommunications operator Orange show the relevance of the model and of the graph-oriented algorithm: these prove to be computationally efficient in solving large scale instances, and significant savings and revenues can be generated through our optimized battery management policies.

How does a battery reduce the energy bill?

Daryanian et al. ( 1989) introduced such a demand response mechanism by using a single battery to reduce the electricity bill by exploiting the variation of the energy prices. In their study, a battery is used in peak-time periods, where the energy costs more and recharged in periods where the energy is cheaper.

How can a multi-battery battery efficiency model be improved?

In addition, further parameters to improve the battery efficiency model should be integrated, such as a more realistic discharge scheme. Moreover, many scenarios in practice involve more than a single battery, and thus the multi-battery setting would be worth studying.

Can batteries be used as backup devices?

In particular, they allow better integration of renewable and decentralized energy sources while maintaining the security of the electricity grid, allowing for greater collaboration between the agents. In this context, batteries can be used as backup devices.
