Control and Energy Management of DC Nano Grid- Connected Solar PV, Fuel cell and Battery Energy Storage System

The interconnection of renewable energy sources with the utility grid, such as photovoltaic (PV) and fuel cells (FC), is a solution that is effective in meeting load demand on the distribution side. The rising demand for energy management systems can be attributed to the widespread use of battery energy storage systems (BESS) in the utility grid. An effective energy management system is proposed in this study for use in a PV and FC-based DC nano grid with BESS, and several operating modes are analyzed and addressed. The most important aspect of it is that it keeps the DC voltage consistent throughout the grid. With the help of the MATLAB/Simulink software tool, many simulation case studies are carried out in this research.
