Cost-effective and Resilient Operation of Distribution Grids and 5G Telecommunication

Joint effort from the Imperial and LSBU teams, their paper "Cost-effective and Resilient Operation of Distribution Grids and 5G Telecommunication" has been accepted to the IEEE PES GM conference that will be held in Orlando, Florida in July 2023.

Abstract—5G base stations have growing importance in an integrated electric power and telecommunication system, for mobile user equipment mobile data supply and demand response in distribution grids. However, demand response through base station’s flexibility can have a growing impact on the power flow of the grid. Additionally, in extreme events, if a power outage occurs at the physical base station, data loads need to be first reconnected to the 5G network, which is essential for the grid to further recover the electricity loads. In this paper, a cost-effective and resilient operation method is proposed to optimally utilize

the flexibility of renewable-based 5G base stations and the data load shedding to recover the data transmission. The flexibility from batteries equipped in the base stations and the flexible associations between user equipments and base stations are considered. The simulation results verify the proposed method can achieve lower energy costs and power losses of the grid in normal operation and a resilient operation in an extreme event.
