Embodiments of the present invention disclose a method and a system for comprehensively optimizing expansion planning of a distribution network containing a distributed energy source and a charging station. The method comprises: establishing a multi-objective optimization function based on a system average power-off duration and a planned annual average cost of the distribution network; determining constraint conditions of the multi-objective optimization function; setting the capacity of a distributed energy and the capacity of the charging station of each node in the distribution network; and according to the capacity of the distributed energy and the capacity of the charging station of each node, the multi-objective optimization function and the constraints, solving the multi-objective optimization function by using the multi-objective perturbation biogeography algorithm; and according to the capacity of the distributed energy and the capacity of the charging station of each node in the distribution networ
