Currently, the high penetration of photovoltaic energy (PV) in the power system raises many challenges due to the instability of this type of energy. To overcome this problem, this study analyzes the Power Factor Correction (PFC) control technique through the existing power grid to support converters integrated with the MPPT algorithm. Then, an experimental circuit model integrating two control methods will be fabricated and evaluated under the actual operating conditions. The experimental process shows that in the case of PFC support, output voltage response is more stable than the case that only uses the simple MPPT algorithm.
