Abstract: In places without a grid, standalone solar PV systems have come to be seen as viable solutions to electrical issues. When creating these devices, it is quite challenging to get a photoelectric system, DC-DC inverter, DC-AC converter, and control system to operate at maximum capacity. In this study, a boost converter, an inverter, and batteries with a bidirectional converter are introduced as a freestanding two stage method. In order to modify the inverter output, a unique virtual synchronous generator (VSG) controller is created and put into practise in this study. To regulate the inverter output and realise the maximum power of the PV system, the VSG element and the maximum power point tracking (MPPT) are utilised in this study. Extensive MATLAB simulations were implemented to verify and evaluate the new control strategy design in a variety of scenarios, including load fluctuations. With the help of several MATLAB simulations, the system output was assessed. Console testing was used in a hands-on experiment for the VSG. We were unable to test the full system since the laboratory lacked the necessary tools.
Keywords: MPPT, DC-DC boost converter, PV array, virtual synchronous generator.
