Standalone base station. 5G network architecture is based on entirely new standards introduced by the 3rd Generation Partnership Project (3GPP). This is the organization that sets international standards for all cellular communications. SA is the new core architecture as defined by 3GPP. It introduces critical changes:
In this paper, the economic model of the backup nanoenergy storage system of the communication base station is firstly built with considering the over-discharge penalty. After that, the hybrid wolf pack algorithm is proposed to solve the model. Finally, a case study is used to verify the effectiveness of the proposed optimization model.
The proportion of traditional frequency regulation units decreases as renewable energy increases, posing new challenges to the frequency stability of the power system. The energy storage of base station has the potential to promote frequency stability as the construction of the 5G base station accelerates. This paper proposes a …
4.2.1 Cavitation is a term used to describe a phenomenon that may occur in a pumping installation and may occur in piping systems because of liquid velocity changes. Cavitation in pipe lines may take place at sudden enlargements of the pipe cross section, at sharp bends, throttled valves or similar situations.
