一种改进构网型逆变器输出电流质量的基波与谐波频率解耦控制方案

Grid-forming inverters (GFI) are used to retain the grid inertia and frequency stability with increasing inverter-based sources in the grid. However, as GFI is essentially a fundamental frequency voltage source, grid voltage distortion would induce significant grid current harmonics. In this article, the limitations of the existing types of GFI harmonic current suppression methods are analyzed fro...
