Technical FAQs 4

How can grid-forming inverters improve grid stability?

The increased penetration of inverter-interfaced renewable energy resources in modern power grids has significantly reduced system inertia, which is critical for maintaining frequency stability. Among emerging solutions, Grid-Forming Inverters (GFMs) have proven pivotal in simulating inertia and enhancing grid stability.

Do inverter-dominated grids affect frequency stability?

The frequency response is assessed following largest power infeed loss by plants technology (IBR or synchronous generator). The results demonstrate that inverter-dominated grid mainly impact frequency stability rather than voltage stability, with the disconnection of weaker PV plants during faults leading to underfrequency load shedding.

Can VSG control increase the inertia of inverter with high penetration rate?

Therefore, with high penetration rate of IBR, the VSG control of inverter is proposed , , . VSG control can increase the inertia of the inverter, and can reduce the system frequency change rate and frequency deviation under the impact of large power shortage in the system, which is conducive to improving the stability of the power system.

What is a grid forming inverter?

A grid-forming inverter operating in Virtual Synchronous Machine (VSM) mode emulates the behavior of a synchronous generator by establishing the grid’s reference voltage and frequency. In doing so, it contributes virtual inertia and damping to stabilize frequency and voltage while facilitating power sharing among inverter-based resources.
