| Summary: | Wind power plants do not provide frequency support subject to disturbances because wind turbine generators (WTGs) are
decoupled from system frequency deviations. To provide frequency regulation from a permanent-magnet synchronous
generator-based wind energy conversion system following the change in system load demand, this paper presents a
basic controller that directly perturbs the rotor-speed reference according to system frequency deviations. In
the proposed approach, the kinetic energy (KE) of the rotating parts of the WTGs is utilized for frequency support,
thus enriching the power system stability. The prominent aspect of opting for this concept is the immediate KE
release or absorption through a step-change in the speed reference. Furthermore, the system proceeds to its normal
operation without causing instability issues. To prove this concept, extensive simulations in MATLAB/Simulink have
been performed, and the results demonstrate its good capability in providing system frequency regulation, resulting
in the enhancement of power system stability. For comparison, simultaneous control of the power-frequency droop
control and DC-link inertial support was also prepared. |
