Under the high penetration of renewable energy, the power grid may features as the weak grid, which contains a large set of grid impedance values and varies of harmonics. The grid-connected inverter can be greatly challenged by this weak grid condition when it is operated as the interface to inject the generated power into the grid. Particularly, the stability problem may be aroused by the grid impedance and the injected grid current can be greatly distorted by the grid voltage harmonics… CONTINUE READING
