Communication Base Station Energy Storage Solutions
This article outlines a replicable energy storage architecture designed for communication base stations, supported by a real deployment case, and highlights key
Model of Base Station Power System The key equipment in 5G base stations are the baseband unit (BBU) and active antenna unit (AAU), both of which are direct current loads. The power of AAU contributes to roughly 80% of the overall communication system power and is highly dependent on the communication volume .
However, the widespread deployment of 5G base stations has led to increased energy consumption. Individual 5G base stations require 3–4 times more power than fourth-generation mobile communication technology (4G) base stations, and their deployment density is 4–5 times that of 4G base stations [3, 4].
To properly examine an energy-optimised network, it is very crucial to select the most suitable EE metric for 5G networks. EE is the ratio of transmitted bits for every joule of energy expended. Therefore, while measuring it, different perspectives need to be considered such as from the network or user's point of view.
Scheme 1: The classic scheme in which the base stations are only powered by grid electricity. Scheme 2: The PV modules are connected in series to obtain higher voltage and are connected to the AC bus of the base station through an inverter with MPPT function. ESS is connected to the 48 V DC bus through bidirectional DC/DC converter.
