The invention discloses an intelligent voltage regulating method for a high-permeability distributed energy sources system based on cluster dividing. A cluster dividing basis, a dividing method and avoltage regulating strategy are still at the exploratory stage, which does not bring convenience to the high-permeability distributed energy sources system for carrying out the subsequent voltage regulation. The invention provides the intelligent voltage regulating method for the high-permeability distributed energy sources system based on cluster dividing. The method comprises the steps: dividingthe nodes in a power system into n sub-communities through the K-means algorithm, taking the reactive power and active power of a controllable PV node as adjustable variables, and carrying out the load flow calculation in the sub-communities; presetting a nonlinear regulation period, carrying out the coarse regulation of the voltage of the controllable PV node through a mixed PSO (Particle SwarmOptimization) algorithm, and determining a working point gamma; and carrying out the fine adjustment of the voltage of the controllable PV node through a linear equation of a node voltage according tothe determined working point gamma. The method can effectively solve an overvoltage problem of a high-permeability renewable energy source, and is good in real-time performances.
