Abstract:
Devices and methods for mechanism-based feedback controller employed in a wind powered power system are provided. A controller can include a vector control-based voltage source converter with feedback control circuitry. The feedback control circuitry is configured to modulate either a power order or a dc-link voltage order to control coupling between voltage and power. The controller can be connected to a wind-based turbine generator of a wind farm and regulate power deployed to a power grid.

Claim (Index 17):
A controller system for a wind-based power system, the controller comprising:\n a vector control-based voltage source converter configured to have feedback control circuitry; wherein the feedback control circuitry is configured to modulate either a power order or a dc-link voltage order, wherein a first input signal into the controller system is an alternating current (AC) voltage, wherein the feedback control circuity is configured to reduce coupling between an active power and a voltage at a point of common coupling, wherein a second input signal into the controller system is a d-axis converter current. wherein the first input signal into the controller system is a voltage at a point of common coupling, wherein the controller system is configured to modulate either the power order or the dc-link voltage order by using the d-axis converter current. wherein the controller is further configured to modulate either a power order or a dc-link voltage order by using the voltage at a point of common coupling, wherein the controller system further comprises:\n an integrator; and \n a high pass filter connected to the integrator, \n wherein the integrator and the high pass filter are configured to modulate the dc-link voltage order, wherein the controller system is connected to a wind-powered turbine generator or a weak grid power system, wherein the controller system is configured for Type-3 wind or Type-4 wind, and wherein the first input signal is a phase-locked-loop (PLL) voltage of the controller system.
