A Seamless Enhancing Grid Stiffness Control Strategy for Harmonic Compensation and Power Ripple Mitigation in Grid-Tied Virtual Synchronous Generator System

Abstract: Grid-forming inverters (GFMIs) are crucial for grids experiencing higher penetration of photovoltaics. Uncertainties in the utility grid make the GFMI system unstable. Thus, using a virtual ...

Research on Hybrid Voltage-Power Switching Control Strategy of Grid-Connected Two-Stage Photovoltaic System for Low Voltage Ride Through Faults

Abstract: For two-stage grid-connected photovoltaic (PV) system, if the low voltage ride through (LVRT) faults occur in the grid side, because the grid voltage falls to a relative low value and the ...
