Base Station Energy Management System 1

How to make base station (BS) green and energy efficient?

This paper aims to consolidate the work carried out in making base station (BS) green and energy efficient by integrating renewable energy sources (RES). Clean and green technologies are mandatory for reduction of carbon footprint in future cellular networks.

What are the components of a base station?

A typical base station consists of different sub-systems which can consume energy as shown in Fig. 4. These sub-systems include baseband (BB) processors, transceiver (TRX) (comprising power amplifier (PA), RF transmitter and receiver), feeder cable and antennas, and air conditioner ( Ambrosy et al., 2011 ).

What are the different types of energy storage facilities?

Newly introduced facilities are: a PV cell, an ESS (energy storage system, a LIB that is equipped with a battery management unit), an IPMS (integrated power management system) and an EMS. The EMS is configured with the client-server model (Fig. 2).

Can a battery bank sustain a BS load?

Their energy storage algorithm controlling the battery bank's SoC is shown to sustain the BS load by effectively managing the solar in a stand alone power system.

Can a base station convert AC power into DC power?

Most base stations are equipped ideally with rectifiers to convert AC power into DC power. However, such a procedure does not fit in with our demonstration test, as it is necessary to connect the storage battery to the controller of the rectifier to achieve a fine control of the voltage.

How many models of mobile phone base stations are there?

There are two models of the mobile phone base stations; one is an indoor model where equipment is installed inside the shelter (Photo 1), and the other Photo 1 Mobile phone base station (indoor model). Fig. 1 Demonstration equipment configuration (indoor model).
