A reconfiguration idea is presented that the network status has been assessed before the reconfigurable computing is optimized and mathematical model of multi-objective optimization network reconfiguration is established. A typical distribution network that contains three feeder 16 nodes is used as an example for analysis. In conclusion, this optimization method can reduce the unnecessary part of reconstruction analysis and when the network needs reconfigumble computing it has achieved good optimization results. The optimization method can improve the distribution network in economy, security and other aspects. The operator can set the target weight value according to the actual situation of the distribution network, which makes the reconstruction scheme more flexible and has more practical significance.
