Abstract:
This thesis book explains a detailed study of how renewable energy can be used in Bangladesh's power system to solve energy problems and make the most of clean energy sources. We're interested in this because we want to see if it makes financial sense to connect renewable energy systems to the power grid. In the background, where people use about 128.19 kWh of electricity every day and the most electricity used at one time is 21.91 kW, we're looking into using sunlight and waste from cows (cow dung) to make electricity. The sunlight here is pretty good, with an average clearness index of 0.521 and 4.65 kWh of sunlight per square metre every day. We're also thinking about the cow dung, which can be used to make electricity. We thought about different ways to set up these systems, and the best way we found is to use a 50 kW solar panel system with a 20 kW inverter, a 48V battery setup, and a 5 kW biogas generator. We came up with four different plans: using both solar and biomass, only solar, solar with batteries, and only biomass. Economically, the plan with both solar and biomass is really promising. We found that you can get back about 30.81% of the money you put in during the first year. It takes about three years and three months to get all your money back. Over the whole time this system works, you end up making about 7.69 times the money you put in. In the end, we want to show that using renewable energy in Bangladesh's power system is a great idea. The plan we recommend with both solar and biomass is not only good for the environment, but it also makes a lot of sense from a practical and financial perspective.
