IEEE Transactions on Smart Grid, 2022 An islanded microgrid (MG) including low-inertia converter-based distributed generations (DGs) is subjected to instability. The virtual inertia concept was proposed to alleviate the stability issues by imitating the synchronous generators behavior. This paper spotlights on the optimization of virtual synchronous generator (VSG) parameters and virtual ...

Parallel inverters control strategy based on adaptive virtual impedance
Journal of Hebei University of Science and Technology, 2023 In the low-voltage microgrid, the connection lines between parallel inverters are different due to the different length and loss, and the active power of the parallel inverters cannot be evenly distributed under the conventional droop control.

Adaptive Impedance-Conditioned Phase-Locked Loop for the VSC Converter Connected to Weak Grid
Energies, 2021 In this paper, an adaptive version of the impedance-conditioned phase-locked loop (IC-PLL), namely the adaptive IC-PLL (AIC-PLL), is proposed. The IC-PLL has recently been proposed to address the issue of synchronisation with a weak AC grid by ...

Actuators, 2023 The integration of a passive elastic element in series between a motor and its load is popular in many human–robot interaction scenarios. By virtually imposing elastic behavior on the motor, an impedance control can act as a second stiffness to such an ...

VSG Control Strategy Incorporating Voltage Inertia and Virtual Impedance for Microgrids
Energies, 2020 Virtual synchronous generator (VSG) control lacks voltage inertia and powerful decoupling capabilities. The voltage of the distributed generator (DG) unit controlled by the VSG will be easily affected by power fluctuations and high-frequency noise, and ...
