Description

technical field [0001] The invention relates to a method for dividing a distribution network island of a power distribution network with an electric vehicle swap station based on a hybrid algorithm, in particular to a short-term island division method for a power distribution network with an electric vehicle swap station. Background technique [0002] With the strengthening of distribution network construction and the maturity of micro-grid technology, the penetration rate of distributed generation (DG) in the power grid is increasing. Although the access of DG to the distribution network can meet the increasing load demand and improve the comprehensive utilization rate of energy, it also makes the structure of the distribution network more and more complicated. When the capacity allocation problem of micro-sources is carried out on the distribution network containing distributed energy, due to the real variability of micro-source output, the optimal capacity allocation dete...
