Power distribution network source network load storage cooperative power coupling method and system based on multiple scenes

The invention belongs to the technical field of power distribution network source network load processing, and discloses a power distribution network source network load storage cooperative power coupling method and system based on multiple scenes. The method comprises the steps that a master station divides network load control areas according to network load grades, reactive power optimization calculation of the whole system is carried out on the basis of obtained real-time data, and reactive power output set values obtained through optimization calculation are issued to substations of the network load control areas according to the criterion that it is ensured that the network loads of all buses are stable and reactive power flow is optimal; the adjustable range of the power distribution network source is analyzed, and a control instruction is sent to a main station; the master station receives the control instruction, and operates a reactive power control mode according to the control instruction to carry
