Power cluster partition can simplify the grid planning

operation monitoring and dispatching control

and has a wide range of engineering applications. Along with the distributed access of the large-scale renewable energy

the problems of over-voltage and power reverse faced by the distribution network are getting more and more severe

and traditional cluster partition method based on a single criterion has been difficult to meet the demand of distribution network planning. By taking the distribution network planning for the renewable energy with high penetration as a scene

the method for cluster partition considering structural and functional property is proposed

in which the electrical distance based modular index is used on the structural property

while on the functional property

the comprehensive performance indicator system is constructed by using the equilibrium degree of reactive power and active power as function index. Meanwhile

to adapt to the comprehensive performance indicators

the basic genetic algorithm is improved and the new chromosome encoding method based on the network adjacency matrix is adopted. A 10 kV actual feeder system is used for the theoretical and algorithm verification

which proves that the results of cluster partition have strong electric coupling

good regulation ability and the equilibrium degree of active power.
