Improvement efficiency of photovoltaic system using modified perturb and observe
The limitation of fossil fuels for electricity generation is a very important problem faced today, so that the use of renewable energy is increasing. The photovoltaic system is an electrical energy generator that converts solar energy into electrical energy. The use of PV is increasing because it is pollution-free, free, and low maintenance. However, PV has low conversion efficiency and an increase in PV efficiency can be achieved if it works at the maximum power point (MPP). So it's needed a maximum power point tracking (MPPT) controller. In this article, a modified P&O (MP&O) MPPT controller is designed for a standalone PV system using a boost converter. MP&O finds the MPP by adjusting the duty cycle of the boost converter based on current and voltage measurements. Based on the simulation results, the MP&O MPPT algorithm has a better performance than P&O. MP&O can follow changes in irradiance and produce greater maximum power and faster tracking time than the P&O algorithm. For some irradiance conditions, MP&O can achieve an average efficiency of 92.65% while P&O is 83.45%.
