Abstract

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 network corresponding to the required solutions of the multi-objective optimization function, optimizing the expansion planning of the distribution network containing the distributed energy source and the charging station. According to the method disclosed by the embodiments of the present invention, a plurality of variables of the distributed energy source and the charging station of an optional node in the distribution network are optimized.

Description

technical field [0001] The invention relates to the technical field of distribution networks, in particular to a comprehensive optimization method for distribution network expansion planning including distributed energy sources and charging stations. Background technique [0002] The distribution network is at the end of the power system and is an important link between the power source and the user. The power supply capacity of the power system to the user must be realized through the distribution network. With the advancement of the intelligent construction and transformation of urban distribution networks, large-scale distributed energy and charging stations are connected to the distribution network, and the distribution network presents the characteristics of large scale, many nodes, miscellaneous equipment, and multiple operation modes. The development of network wiring is the coexistence of multiple power supply modes; changes in network topology, investment in new equ...
