AN OPTIMAL POWER DISTRIBUTION SCHEME FOR THE DENSE NETWORK COMPOSED OF 5G BASE STATIONS BASED ON VIRTUAL ENERGY BACKUP

Abstract

As the digitalization is sweeping the world, the amount of DC load increases tremendously, among which the dense networking of 5G base station is a typical example. This paper firstly analyses the demand of 5G network and the difference between its 4G counterpart, then aiming at minimizing the station backup energy and hence the operating cost of telecommunication company, this paper proposes the DC power feeding scheme and integrates the concept of virtual energy backup (VEB), i.e., by connecting the 5G stations and energy storage to the DC network, the centralized energy storage act as an energy backup to the distributed 5G stations. For the operation of the 5G power feeding network with VEB, this paper proposes the multi-objective power flow (MOPF) model and implemented a solving procedure. The benefit of the proposed scheme is demonstrated by a full day simulation, and the result shows a very good energy and cost saving. The study has the extensive applicability and practical significance to both the research and construction of 5G dense network.
