For the rotor speed of variable speed wind turbine (VSWT) is decoupled from system frequency, the system equivalent rotary inertia and primary frequency control ability are decreased with wind power penetration growing continuously. To solve the problems, VSWT with additional frequency control was studied. The dynamic characteristics of input and output power of VSWT during participating in system frequency regulation are analyzed. The relationships between the active power increments and the duration of VSWT participating frequency control are quantified. A coordination frequency control strategy base on time sequence control is proposed. According to the control strategy, the VSWTs can participate in frequency regulation depending on the coordination of wind speed, power increments and duration. The simulation results demonstrate the effectiveness of the proposed control strategy, which can make full use of the frequency regulation ability of VSWTs as well as minimize the negative effects on system frequency.

Primary Frequency Control

In this paper, a nonlinear fractional-order PI (NL-FO-PI) controller is proposed for primary frequency control (PFC) of a wind farm based on the squirrel cage induction generator. The new structure composites a fractional-order operator and nonlinear function to achieve better control performance for the PFC system. The benchmarking process is demonstrated by investigating the performance of fractional-order PI (FO-PI) and nonlinear PI (NL-PI) controllers. Initially, the controller is applied to a single-area power system for design and stability study and then extended to the two-area interconnected wind farm to validate the applicability in the more realistic power system. The proposed control method ensures the balance of power and keeps the system frequency within a suitable range. The simulation results demonstrate that the proposed NL-FO-PI controller provides less percentage overshoot, settling time, rise time, and peak time than other controllers.
