Abstract:
Base Transceiver Station is considered as the heart of mobile telecommunication system. Millions of phone calls, SMS and enormous number of data is being sent and received in every second through these BTS all over the world. Therefore, BTS are the devices which need to run 24/7 without being disturbed by any sort of electric crisis or shortage. Bangladesh is not fully compatible to meet the growing electricity demand of the whole country. Although it varies from day to day, on an average we predicted there are two hours of load shedding period in every distribution line of entire country. Therefore, it requires 24/7 electricity supply to all the BTS of all operators. Our concern is during the off grid period. It is found that all the operators use diesel generators for the off grid time. Our target is to compare the feasibility of using alternative power sources to minimize the cost of the system, minimizing carbon emission and reducing the dependency on the fossil fuel. Firstly, we have analyzed the previous and recent data of diesel, solar and fuel cell power sources. A new we model is proposed to combine the sources with backup of diesel generator which can minimize the cost and fulfill our target. We also analyzed the future of carbon emission which our proposed model can reduce after a certain period of years.
