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 reduct.
What is a hybrid solar/wind based power system?
A hybrid solar/wind based power system comprises PV array, wind turbine, battery bank, controller, inverter, cabling, and other devices (such as fuses etc.). The layout of a BS employing conventional as well as renewable energy sources is shown in Fig. 5.
The hybrid systems comprising conventional and RESs have been shown to significantly decrease the overall cost of the isolated power systems over their total life cycle ( Karki and Billinton, 2001 ).
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.
Can a BS install a solar array or a wind turbine?
However, the foremost challenge in equipping a BS with a solar array or a wind turbine is the sizing and configuration of the systems. Sizing of PV arrays and turbines is directly effected by the fact whether or not a BS is off-grid or on-grid.
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 wind turbine power a BS?
The main challenge is the sizing of the PV panels and the wind turbine to power a particular BS for which feasibility studies have been done using actual site data as well as simulated data, using software like HOMER, that provide the size and configuration of wind turbines and PV panels ( Deshmukh and Deshmukh, 2008 ).
