A Novel Virtual Impedance Method for Interfacing Renewable to Grid with High Impedance
2023 IEEE PES Innovative Smart Grid Technologies - Asia (ISGT Asia), 2023Currently, grid-following inverter (GFL) has become a vital component in the integration of renewable energy sources into power grids. A Modified Virtual Impedance - Phase Locked Loop (MVI-PLL) method is proposed to address instability problems that occur when using a PLL under high grid impedance conditions in GFL.

Virtual-Impedance-Based Control for Voltage-Source and Current-Source Converters
IEEE Transactions on Power Electronics, 2015 The virtual impedance concept is increasingly used for the control of power electronic systems. Generally, the virtual impedance loop can either be embedded as an additional degree of freedom for active stabilization and disturbance rejection, or be ...

Impedance control with virtual compliance
Proceedings of the Third International Workshop on Robot Motion and Control, 2002. RoMoCo '02., 2003In the paper a new concept of impedance control for a simple 1D dynamical system has been presented. The new approach lies in treating a task of reaching a contact plane and generating desired force on environment as one control problem that can be realized by one coherent control equation.

Damping Effect of Virtual Synchronous Machines Provided by a Dynamical Virtual Impedance
IEEE Transactions on Energy Conversion, 2021Virtual synchronous machines (VSMs) emulate the swing equation for grid synchronization and inertia provision. Usually, a large damping coefficient is necessary in VSMs to provide equivalent damper winding effect, which is, however, not aligned with the fact that the physical swing equation of synchronous generators (SGs) contains only a small ...

Virtual impedance design of virtual synchronous generation in microgrid
2014 International Power Electronics and Application Conference and Exposition, 2014The adoption of virtual synchronous generation (VSG) control can maintain the stability of voltage and frequency in power electronic interfaced mircogrid. In this paper virtual impedance is added to the VSG control strategy in order to improve the system control performance in resistive-inductive line impedance, the influence of virtual impedance on ...

Virtual impedance control for preshaping of a robot hand
Proceedings of the 41st SICE Annual Conference. SICE 2002., 2003A simple and fast virtual impedance control algorithm is presented for a dexterous robot hand to perform the complex preshaping and grasping movements. This algorithm integrates two conflict impedances for the fingers to separate between each other during approaching to grasp the object.

Power Flow Analysis for Low-Voltage AC and DC Microgrids Considering Droop Control and Virtual Impedance [PDF]
IEEE Transactions on Smart Grid, 2017 In the low-voltage (LV) ac microgrids (MGs), with a relatively high R/X ratio, virtual impedance is usually adopted to improve the performance of droop control applied to distributed generators (DGs). At the same time, LV dc MG using virtual impedance as
