Abstract

The invention discloses a multi-objective AC / DC power distribution network planning method and device, which are used for considering the economy and reliability of power distribution network planningand achieving collaborative planning of multiple objectives. The method comprises the following steps: acquiring planning parameters of a preset planning area, and determining optimization objectivesand constraint conditions of the multi-objective AC / DC power distribution network by adopting the planning parameters, wherein the optimization target comprises a construction cost target and a reliability target; establishing a multi-objective optimization planning model by adopting the planning parameters, the optimization objectives and the constraint conditions; solving the multi-objective optimization planning model by adopting a preset multi-objective evolutionary MOEA / D algorithm, and outputting an optimization variable; and determining a compromise solution of the optimization variable, and planning the multi-target AC / DC power distribution network by adopting the compromise solution. Economy and reliability of planning are both considered, and collaborative planning of multiple targets is achieved.

Description

technical field [0001] The invention relates to the technical field of distribution network planning, in particular to a multi-objective AC / DC distribution network planning method and device. Background technique [0002] In recent years, with the development of power semiconductors and power electronics technology, a large number of applications of DC loads, DC distribution network has attracted more and more attention from the power industry due to its strong transportation capacity, low loss, and the ability to connect a large number of distributed equipment. . [0003] At present, the application of DC distribution network is still in the experimental and experimental stage, and there is still a distance from promotion and practical application. Although with the advancement of technology and the continuous advancement of experiments, the extensive application of DC distribution networks has a considerable theoretical basis, but there are still no mature methods and sol...
