The purpose of this thesis is to explore the importance of Smart Grid and to conduct a full feasibility analysis of its implementation in Bangladesh. A smart grid is an electric power system that improves grid accuracy and effectiveness by reacting to systemic disruptions proactively. For a developing country like Bangladesh, it is important for both increased electricity generation and to prevent power outage. A basic necessity for individuals and economies is the efficient transmission and distribution of electricity alongside vital energy supplies. The thesis examines and describes the features and economic topology of Smart Grid, as well as potential solutions to Bangladesh's power issue. It also covers the sustainable transmission and distribution of electricity, as well as the integration of communication and smart monitoring technologies of smart grid.
