A reactive power voltage control partitioning based on modified shuffled frog-leaping-K-means clustering algorithm is proposed taking into account the characteristic of reactive power voltage control partitioning.According to idea of control of no power source

nodes in electric networks are regarded as classification of object

control of each no power source on it form characteristic index

all the nodes in the system are mapped into a multi-dimensional space.The modified shuffled frog leaping-K-means clustering algorithm is used to obtain partition number of the controlled nodes.Partition of electric generator nodes is determined by using merge principle.IEEE 39 system is analyzed and calculated using the method

partitioning result is compared with the result of other algorithms to verify the accuracy and feasibility of the proposed algorithm.
