AI Technical Summary
When wind turbines are configured as virtual synchronous machines, they face the problem of increased mechanical load, which is difficult to solve effectively with existing technologies.
By employing electrical storage devices such as batteries, supercapacitors, flywheels, and superconducting magnetic energy storage devices, and connecting them to generators and inverters via DC link circuits, combined with power controllers, charging controllers, and DC link controllers, virtual synchronous machine simulation of wind turbines and reduction of mechanical load can be achieved.
The use of electrical storage devices reduces the demand on generator power and lowers the mechanical load on wind turbines. Especially under low wind conditions, it avoids excessive absorption of rotor power and improves the stability of grid power and mechanical systems.
