“…A second‐generation GSM mobile base station consisting of one number BTS with three transceivers was considered in this study. The maximum power consumption of air conditioner is considered as 1.8 kW, whereas the BTS equipment's power and miscellaneous loads (battery charging load and lighting) are 1500 W and 480 W, respectively . Normally, the full load will be the constant BTS equipment load, miscellaneous load, and the air conditioner running power, but when the temperature goes low, the air conditioner can be configured to switch off automatically, thereby minimizing the energy consumption .…”

In recent times, hybrid renewable energy systems are increasingly being utilized to provide electricity in remote areas especially where the grid extension is considered too expensive. This study presents the results of techno-economic analysis of hybrid system comprising of solar and wind energy for powering a specific remote mobile base transceiver station (BTS) in Nigeria. All the necessary modeling, simulation, and techno-economic evaluation are carried out using the assessment software package HOMER (Hybrid Optimization Model for Electric Renewable). Two best optimal system configurations namely PVdiesel-battery and PV-wind-diesel-battery systems are compared with the conventional stand-alone diesel generator (DG) system. Findings indicated that PV array (10 kW) -DG (5.5 kW) -battery (64 units Trojan L16P) is the most economically viable option with the total net present cost of $69,811 and per unit cost of electricity of $0.409. The sensitivity analysis is also carried out to find the effects of probable variation in solar radiation, wind speed, and diesel price in the optimal system configurations. Finally, the environmental benefit of hybrid systems over the conventional stand-alone diesel system is described. The obtained results show that the hybrid PV-diesel-battery system provides a reduction in CO 2 emissions of about 16.4 tons per year as compared to the stand-alone DG system.

“…A 2 nd generation (2/2/2) GSM mobile base station consisting of one BTS with three transceivers was considered in this study. The maximum power consumption of air conditioner is 1.8kW, while the BTS equipment power and miscellaneous load (battery charging load, fans and lights) are 800W and 480W respectively [12]. Normally, the full load will be constant to the BTS equipment load, miscellaneous load and the air conditioning system, but when the temperature goes low, the air conditioner can be configured to switch off automatically, thereby only the BTS equipment and the miscellaneous load will be powered.…”

Hybrid energy systems are becoming attractive for providing electricity in remote areas due to excessive expenditure of grid extension, increase in oil price and advances in renewable energy technology. Optimal sizing of components can reduce the cost of hybrid systems. This article illustrates the size optimization of solar-wind-diesel generator-battery hybrid system designed for a remote location mobile telecom base transceiver station in Nigeria. Different energy combinations have been analyzed using HOMER 2.81 (Hybrid Optimization Model for Electric Renewables) in order to determine an optimal model. Simulation results show that the hybrid energy systems can minimize the power generation cost significantly and can decrease CO 2 emissions as compared to the traditional diesel generator only.

Nowadays, renewable energy plays an important role in electricity production. The use of renewable energy sources for remote telecommunication systems has become more popular recently due to technological advancements and lower costs. Because, the telecom base transceiver station (BTS) requires uninterrupted power supply to ensure reliable communication services. At present the problem is tackled by using diesel generators. Diesel generator systems require regular maintenance and it is costly. It generates noise pollution. Transportation and storage of diesel is also a major problem in remote areas [4]. This paper gives the discussion about efficient dual input converter for hybrid solar-wind energy systems to supply telecom in rural areas. So, the objective is to investigate and design a suitable fused converter topology for hybrid solar-wind systems. The improvement in efficiency with MPPT and without MPPT controller is calculated by simulating with MATLAB/SIMULINK software. An elaborate element wise comparison between these topologies is reported.
