Low-Frequency Defense Strategy for Wind Turbine Participating in Power Grid Frequency Adjustment

Abstract With the continuous increase of wind power permeability, dynamic behavior system also changes, which has a great impact on setting low-frequency load-shedding scheme. The original scheme no good adaptability to high-permeability power. So, this article analyzes principles turbines in grid frequency control. This paper expounds principle strategy configuration. Connecting with actual operation simulation, simulation results show that modulation can significantly reduce load shedding process loads and positive impact.
