Voltage-Modulated Direct Power Control for a Weak Grid-Connected Voltage Source Inverters
IEEE transactions on power electronics, 2019 In this paper, we design a voltage-modulated direct power control (VM-DPC) for a three-phase voltage source inverter (VSI) connected to a weak grid, where the phase-locked loop (PLL) system may make the system unstable if the conventional vector current ...

Virtual Inductance for Stable Operation of Grid-Interactive Voltage Source Inverters
IEEE transactions on industrial electronics (1982. Print), 2019 In this paper, a feedforward virtual inductance control strategy is developed for the stability of voltage source inverters (VSIs) in weak grids. A weak grid is characterized by a low short-circuit ratio and a low inertia constant, in which VSIs become ...
