Green wireless networks or energy-efficient wireless networks have
gained popularity as a research topic due to the ecological and economic
concerns of cellular operators. The specific power supply requirements for the
cellular base station, such as cost-effectiveness, efficiency, sustainability, and
reliability, can be met by utilizing the technological advances in renewable
energy. There are numerous drivers for the deployment of renewable energy
technologies and the transition towards green energy. Renewable energy is
free, clean, and abundant in most locations throughout the year. Accordingly,
this work proposes a novel framework for energy-efficient solar-powered base
stations for the Oman site, specifically for off-grid locations where fuel transportation for diesel generator (DG) is a serious concern. To demonstrate the
effectiveness of the proposed system for off-grid sites, the Hybrid Optimization
Model for Electric Renewables optimization software is adapted by considering real-time conditions and its technical feasibility. Different cost factors such
as capital cost, salvage cost, replacement cost, operational, and maintenance
cost of PV panels, inverters, and batteries also undergo extensive analysis.
From the observed results, the total net present cost (NPC) of the proposed
system is $27,887, while the net NPC of the DG is estimated at $32,900.
Remarkably, the proposed scheme can potentially achieve considerable savings in the operational expenditure at approximately 15.24%. Indeed, these
outcomes can provide profound economic, technical, and ecological benefits
to the cellular operators of Oman. It also ensures a sizeable reduction in greenhouse gas that supports sustainable green wireless network deployment
in remote areas.
