Abstract

The invention provides a partition method of a power distribution network island with an electric vehicle battery swapping station based on a hybrid algorithm. The method comprises the steps of (1) inputting a network initial parameter, (2) setting the variable of the hybrid algorithm, (3) initializing a local optimal vector and a global optical vector, (4) calculating particle fitness, (5) updating the local optimal vector and the global optical vector, (6) updating a particle position value, (7) carrying out convergence testing, and (8) outputting a result. According to the method, a quantum evolutionary algorithm and a JADE algorithm are combined, and the partition method of the power distribution network island with the electric vehicle battery swapping station is provided.

Description

technical field [0001] The invention relates to a hybrid algorithm-based method for dividing an island of a distribution network with an electric vehicle replacement station, in particular to a method for dividing a short-term island of a distribution network with an electric vehicle replacement 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 continues to increase. Although DG access 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 dealing with the micro-source capacity allocation problem of the distribution network containing distributed energy, due to the real variability of the micro-source output, the optimal capacity allocation determined at a certain...
