Preset Performance Theory Based Station Control Strategy of Wind Farm for Frequency Stability

The ability of wind farms to participate in system frequency adjustment is required for a high proportion renewable energy power system. This paper reinterprets frequency stability from the perspective of preset performance control, and proposes a novel power control strategy for wind farms. This strategy gives the guidance of when and how much wind power is required to be injected into power system for frequency stability control. The advantage of the proposed strategy is that it only takes the frequency variety as the input variable, which makes it convenient for realizing the local control of the station. Finally, the correctness and validity of the proposed strategy is verified in MATLAB Simulink platform.
