Abstract
Renewable energy sources (RES) are critical to meeting the world's predictable energy needs. The present electrical system design, which is built on electrical components has various unpredictable loads and distributed generators (RESs), which has resulted in the emergence of several PQ difficulties. This concept offers a combination of DFIG with a boost converter fed grid connected network controlled by P&O MPPT. It is proposed to build and a three-phase grid connected network with a novel configuration based on the use of winds. It incorporates a high-gain single-switch dc to dc Boost converter with P&O MPPT. The maximum power point detection method assists wind power plants in overcoming fluctuation in voltage concerns. A PWM rectifier is also employed to convert the DFIG's AC voltage to DC, and is then supplied into the MPPT method's boost converter-based output. To synchronize the grid, PI controllers and D-Q theory are utilized. The dc-link stable voltage is preserved in this study by using a PI controller. Furthermore, this reduces THD and conforms to the IEEE harmonic guideline. At last, we will run a series of numerical simulations with the MATLAB 2021a / Simulink program to evaluate the suggested controls. The MPPT tracking efficiency between the controllers shown the value as 88% for P&O.
