Research on high-frequency generation tripping strategy for isolated power grid in wind-hydro power generation area

After the large-scale integration of wind farms into regional power grids, traditional high-frequency cutting generator strategies no longer fit the new way of grid operation. This paper conducts a specialized study on isolated power grids containing both hydro and wind power that may experience high-frequency issues. It fully considers the impact of wind farms and the problem of over-shedding in large-capacity single-unit generators. Combining the characteristics of the isolated grid and the properties of different units, an optimized method for high-frequency load shedding strategies is proposed. Simulation analysis is carried out, achieving good results.
