Abstract

Studying the introduction design of a stand-alone solar photovoltaic (PV) system with a disturbance-and-observation (P&O)-based algorithm for maximum power point tracking (MPPT) is an important topic for improving the performance of solar energy systems. The efficient energy system is designed by using solar photovoltaic panels consisting of a number of cells, using P and O algorithms for effective tracking of maximum power, and performing comparative analysis using the traditional model without the MPPT algorithm. In this approach, the terminal voltage of the photovoltaic cell is always set according to the MPP voltage and duty cycle setting directly in the system. The control loop and calculations have been simplified to reduce the time needed to adjust the console gain. The system has a solar panel, MPPT (maximum power point tracking) with controller, DC converter, and a single-phase VSI (voltage source inverter). The proposed system was simulated using MATLAB/Simulink model.

Keywords: Photovoltaic Cells Generator (PVG), Maximum Power Point Tracking (MPPT), perturbs and observes (P&O) Controller, Single Phase VSI (Voltage Source Reflector).
