Technical FAQs 4

What is VSG in a static grid-connected inverter?

The VSG strategy not only emulates the characteristics of TSG but also participates in voltage regulation, inertia support, and other control functions, while endowing the static grid-connected inverter with rotational inertia and damping characteristics, so as to enhance its ability to suppress fluctuations (Guo et al., 2023).

How does a grid-connected inverter improve LVRT of a VSG control system?

This enables the grid-connected inverter to stay connected to the grid and successfully achieve LVRT of the VSG system, thereby enhancing the anti-interference capability of the VSG control system.

How does a VSG control a power inverter?

By use of the interface mechanism of the inverter, the VSG controls the power input and output. Figure 7 shows typical control techniques including droop control, voltage and frequency control, and power control. VSG and grid-connected control mechanism.

Does VSG synchronize with the power grid?

The transient stability analysis has been conducted to guarantee synchronization between the VSG and the power grid, especially in the face of severe grid disturbances. Simultaneously, the reactive power has been increased with the proposed IV-VSG control to support the power grid voltage.
