Acknowledgement We would like to express our sincere and firm gratitude and pay a lot of thanks to our honorable thesis supervisor Dr. Abdul Hasib Chowdhury, Professor, Department of Electrical and Electronics Engineering for his constant supervision to carry out the thesis. He extended his helping hand by providing us encouragement, inspiration, facilities and valuable feedback throughout the course of this thesis. 6
1.0 Objective The objective of our work is to design a grid connected solar PV system for the BRAC University campus. 2.0 Overview 2.1 Why use solar power The main sources of world’s energy generation are the fossil fuels (gas, oil, coal) and nuclear power plants. Due to the usage of fossil fuels, green house gases (CFC, CH4, O3, but mainly CO2) emit into the atmosphere. From the nuclear power plant, carbon is released in a small amount (90 grams equivalent of carbon dioxide per kilowatt hour). [1] But the radioactive waste remains active over thousand years which is a potential source of environmental pollution. Figure1. Sources of carbon dioxide emissions [2] Figure1 shows that electricity generation is source of the highest emission of carbon dioxide. So, production of this clean energy is actually contributing the highest towards global warming. Global warming as well as the environmental pollution is, in our times, the greatest environmental threat to human being. On the other hand, there is an alarming energy crisis world wide as fossil fuel reserves decrease and the ageing power plants are going to close in near future. From the aspect of global warming and shortage of natural gas, scientists and engineers are looking for clean, renewable energies. Solar energy is the one of the best options. Because the earth receives 3.8 YJ [1YJ = 10 24 J] of energy which is 6000 times greater than the worlds consumption. [3] Bangladesh is facing an acute shortage of energy. Natural gas is the main source of 7
