This work presents an enhanced multilayer second-order generalized integrator (EMSOGI) based control approach for a double stage single phase topology based solar PV array interfaced with the grid. This PV system is integrated into the grid at the DC bus of the voltage source inverter (VSI). The PV system satisfies the nonlinear load demand at the PCC (Point of Common Coupling) and feeds the excess power to the grid. The control is able to transfer the power even when the system is subjected to adverse grid conditions. The control is able to solve the inherent problems of the most popular controller used, that is, SOGI and its advanced versions. The boost converter is operated using a PO (Perturb and Observe) algorithm to maintain the peak power point tracing from the solar PV module. Furthermore, the obtained results of a developed model in MATLAB SIMULINK platform are observed to show that the IEEE-519 standard is duly followed under various adverse grid conditions. © 2020 IEEE.
