This article proposes a virtual synchronous generator control strategy for grid-connected inverter based on sliding mode control and virtual adaptive inductance.
This article proposes a virtual synchronous generator control strategy for grid-connected inverter based on sliding mode control and virtual adaptive inductance.
In this paper, an improved control method of grid-connected inverter under the weak-grid situations is presented to reduce the harmonic oscillation. In Section 2, the control

This article explains why the lack of inertia in grid-forming inverters can impact the grid and how to alleviate the issue with a virtual synchronous generator.
For this purpose, a strategy of grid-connected control of VSG with virtual impedance is proposed. Firstly, the VSG mathematical model is established and virtual impedance is

We applied control by the virtual generator model of algebraic type to two inverters, and performed experiments with operation in grid-connected mode and island mode.
Anyone interested in modelling and testing DER grid support by providing virtual inertia is welcome to use this model and send us their feedback. This application example is included in
