The solar insolation level is maintained at 1000 W/m2 during steady-state operation. The harmonics analysis of the source current and voltage of phase ‘a’, , load current and voltage of phase ‘a’ , is shown in Figure 6(a),(b),(c)&(d) and found satisfactory as per IEEE519 standards. The DC bus first-order controller's performance is observed under a polluted grid with a non-linear load, as the bode plot is shown in Figure 7. The magnitude plot and the frequency plot of the closed-loop DC bus system show the dc component's attenuation and low-frequency component and result in a stable system.
