The continuous increasing penetration rate of new energy generations and diversified loads are making how to a-chieve rapid coordination of internal load power in complex distribution network systems an urgent problem.This paper first analyzes operation generalized short-circuit ratio which reflects relative strength of AC system when new energy sources are connected to the grid at any power.It second proposes the optimization scheduling strategy for distribution grid source-load power based on multi-time-scale information,and further establishes daily and real-time power scheduling plan model.Simulation analysis conducted using MATLAB/Simulink has shown that the given strategy for grid partitioning of distribution network system and the introduction of operation generalized short circuit ratio constraints in the built model can fully leverage the advantages of grid optimization and coordination of source load power,improve new energy absorp-tion and consumption rate,and enhance the resistance of distribution network to source-load fluctuations.
