Grid-connected Virtual Synchronous Machine using Virtual Inertia Control

OODBODHAN
System frequency stability becomes more difficult to maintain as system inertia steadily declines due to quick spread of inverter based renewable energy. Virtual Synchronous Generator (VSG) control is one of major solutions to this problem since it makes grid-connected inverters mimic inertial and damping properties of traditional synchronous machines.

Analytical Inertia Identification of Doubly Fed Wind Farm with Limited Control Information Based on Symbolic Regression

Applied Sciences
The integration of large-scale wind power clusters significantly reduces the inertia level of the power system, increasing the risk of frequency instability. Accurately assessing the equivalent virtual inertia of wind farms is critical for grid stability.
