The grid voltage is nominal grid voltage at 0.22 s. The THD of the inverter output current is 1.21 % during the period where the grid is injected by DC components. harmonics. Grid voltage and inverter output current are given in Fig. 3-35. The instantaneous active power and reactive power are displayed in Fig. 3-36. The harmonics injected grid
Grid-connected inverters (GCI) are used to feed power from renewable energy distributed generators into the grid*. They are widely used for this purpose. Repetitive control (RC) enables such inverters to inject high quality fundamental-frequency sinusoidal currents into the grid.
In [12, 46-48], the grid-tied inverters are controlled as a voltage source. However, the current output of the voltage controlled grid-tied inverter largely depends on the grid voltage quality. In this thesis, the grid-tied mode inverter is seen as a current source from the grid side, and the inverter output current is directly controlled.
The zero drift occurring to the sampling conditioning circuit of the non-isolated grid-connected inverter will make the output develop a DC component, thus resulting in system failure and posing safety risks. According to the IEEE standard 1547-2003, the DC component injected into the grid side should be less than 0.5% of the rated current.
