Active power distribution network flexibility resource coordination optimization method and system

The invention provides an active power distribution network flexibility resource coordination optimization method and system, and relates to the technical field of power system power distribution network planning, and the method comprises the steps: building an uncertainty scene and probability distribution considering a comprehensive norm based on the historical data of wind and light output, and carrying out the formulation of a coordination planning scheme of a power distribution network in a typical scene and a severe scene. And quantifying response models when different types of flexible resources face the flexible requirements, and quantifying the flexible requirements of the power distribution network in each scene. And constructing an objective function containing the flexible resource planning construction cost, the power distribution network operation cost and the annual income of the power distribution network. And constructing a power distribution network security constraint, each flexibility reso
