The invention discloses a method for partitioning a power network through dividing and merging based on electric characteristics, comprising the following steps of: firstly, dividing the power network into a looped network part and a tree-like part according to the electric structural characteristics of the power network; and then, coordinately finishing the electric partition of the whole network by using a mixed partitioning method obtained through the combination of an electric coupling degree portioning algorithm and a topological connection relation portioning algorithm. According to the method, a huge power network model is divided in advance, thus only a looped network is needed to be subjected to sensitivity calculation. The model is simple, the calculation scale is reduced, the calculation time is greatly shortened, and the real-time online requirement can be met.
