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).

What is virtual synchronous generator (VSG)?

Front. Energy Res., 10 January 2024 A virtual synchronous generator (VSG) strategy can introduce the rotational inertia and damping characteristics of the synchronous generator to the static inverter, e.g., PV, wind generation, and ESS, which are used to enhance the system frequency support characteristics of the micro-grid.

Can VSG improve power grid integration?

Nowadays, although significant progress has been made in the research field of VSG technology, many problems have to be further solved, such as suitable coefficient definition and voltage support. Therefore, many researchers have proposed different improvement control methods of VSGs to enhance the capability of integrating the power grid.

What is VSG control technology?

In , this concept was extended to a multi-stage system, and a method for balancing the State of Charge (SOC) of each battery module was proposed. When compared with traditional droop control and PQ control, VSG control technology offers the advantage of simulating the external rotor characteristics of a synchronous generator.
