Layered collaborative frequency modulation method for power distribution network containing distributed wind storage

The invention discloses a hierarchical collaborative frequency modulation method for a power distribution network containing distributed wind storage, and the method comprises the following steps: (1), carrying out the regional division of nodes of the distributed power distribution network through employing the access position of a wind storage device based on an improved module increment fast Newman community discovery algorithm; (2) layering and partitioning the power distribution network through reactive compensation and active power reduction, and screening nodes to form a priority adjustment node set; (3) realizing global information accurate sharing of priority nodes for the wind storage of the subarea subset subjected to active reduction through a global information consistency sharing algorithm, and ensuring the consistency of the information; (4) the priority node determines the optimal load shedding rate of each wind storage unit according to the obtained information by taking the minimum support p
