Power grid extreme scene extraction method and device based on convex hull, equipment and medium

The invention discloses a convex hull-based power grid extreme scene extraction method, apparatus and device, and a medium. The method comprises the steps of obtaining a time sequence scene variable matrix for extraction of a target power grid extreme scene; taking each scene as a point of a state variable space, and constructing convex hulls of corresponding points of N scenes in the state variable space; and acquiring a scene represented by points on the convex hull boundary surface and the vertex as a power grid extreme scene. According to the method for extracting the extreme scene of the power grid, the extreme operation mode of the power grid is extracted by using the convex hull algorithm, which is different from the typical operation mode extracted by using a clustering algorithm in most of research at present, and the regional net power is selected as a variable, so that the dimensionality is reduced, and the physical significance between data is reflected; direct data is provided for cross-regional
