Abstract

The invention discloses a power distribution network reconstruction multi-objective optimization method containing section switch configuration. The method comprises the following steps: constructing a global optimal multi-objective power distribution network reconstruction model for system reliability, electric energy loss as well as section switch installation and operating cost; using an ant colony algorithm to solve the reconstruction model; obtaining an optimal solution of the multi-objective power distribution network reconstruction model; and optimizing the quantity and positions of power distribution network switches according to the optimal solution so as to realize the global optimal multi-objective power distribution network reconstruction. The method has the beneficial effects that the system reliability can be greatly improved through optimal configuration of section switches according to the method provided by the invention, and the overall system cost can be greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of power system distribution network automation, and in particular relates to a multi-objective optimization method for reconfiguration of distribution network including segmental switch configuration. Background technique [0002] With the rapid growth of society's demand for electricity, for power companies, transmission reliability and transmission efficiency are becoming more and more important. Power outages generally focus on the distribution network level. In order to improve overall customer satisfaction with electricity use, power companies need to improve power supply reliability, which has become one of the priorities of power companies in the planning and operation stages. On the other hand, most of the power loss occurs in the distribution network. Therefore, the planning and operation of the distribution network must pay attention to the reduction of losses at the same time, so as to improve t...
