Abstract
Bangladesh is a tropical and fourth rice-producing country in the world. Bangladesh has enough potential to produce electricity from solar photovoltaic (PV) and biomass. The aim of this work is to analyze the feasibility of hybrid solar PV and biomass generator (BG) based supply systems for providing sustainable power to the off-grid macro cellular base stations (BSs). The technical and economic aspects of the introduced system have critically been examined using the Hybrid Optimization Model for Electric Renewables (HOMER) optimization software under a wide range of network configurations. Besides, the wireless network has extensively been evaluated using Matlab based Monte Carlo simulations in terms of performance metrics such as throughput and energy efficiency, considering the dynamic traffic profile. Numerical results demonstrate that the hybrid solar PV/BG system is an attractive solution to the challenges of developing a green cellular network in the context of geographical location like Bangladesh for several advantages. The research finds that the hybrid supply system has sufficient excess electricity and backup capacity that increase the system reliability. It also identifies that the proposed system indirectly minimizes CO 2 emission by reducing the biomass burning in cooking purposes. Finally, the outcome of the hybrid solar PV/BG system has been compared with those of other supply schemes for justifying the system validity.
