Optimization and Cost-Benefit Analysis of the Photovoltaic System Connected to the Grid at Daffodil International University

Abstract

Growing energy consumption has made energy security a more pressing problem, necessitating the use of green resources. Solar is the one of the best resources that don’t any kind of damage of environment. Using sunlight energy by solar panel we can use as replacement of our generated electricity that is produce by coal or liquid fuel. This kind of fuel is not sufficient for our human demand and also harmful for environment. In Daffodil International University we want to build up a solar based power plant. So, the investigation will be running on the rooftop of the Engineering Complex and YKSG-2 (hall) of Daffodil International University. The university located at Birulia, Savar, Dhaka. By Homer Pro software we get a result that is the Present worth is $ 86403 and our return on investment is 9%. A sensitivity analysis was also conducted to assess the impact of differences in radiation from the solar (4.35, 5.22, 6.10 kWh/m2/day), PV capacity (100 kW, 150kW, 200 kW), and grid prices ($0.10, $0.08, $0.11 per kWh) upon that optimum configuration. This study found COE is $ 0.0678. This research evaluates the system's effectiveness and demonstrates that, based on real net expenses and energy costs, the system is economically viable. So, we say, our concern is not only reducing our electricity cost also care of our environment. An electrical inverter constantly connects a PV device to the grid. The performance and design of inverters enable many of the essential aspects of PV technology. As a result, there is a need for converter versions that are appropriate for researching PV systems. Several distributed generation (DG) modes are described in this article, including switching and averaging modes appropriate for various test scenarios and inverter-specific operation modes. Inverters' ability to locate undesirable islands rapidly and ultimately remove them in the case of a grid failure is a crucial function. This study examines various active anti-islanding methods with accurate voltage and frequency notes. Keywords: Solar Panel, Inverter, Grid, Cost of Energy, Homer Pro.
