Abstract

The invention discloses a direct current convertor station containing power supply recovery route optimization method based on an artificial bee colony algorithm. The maximum ratio between electric energy production and recovery time in a recovery process of a to-be-recovered power supply is taken as the optimization target; a partial optimized power transmission path of a to-be-started power supply is solved based on a Dijkstra shortest route algorithm; and a global optimal recovery route is solved based on the artificial bee colony algorithm. The power supply recovery route optimization method comprises the steps of 1, initializing power supply recovery sequence codes; 2, searching a shortest route from an electrified system to the to-be-recovered power supply by adopting the Dijkstra algorithm; 3, performing technological verification on the to-be-recovered power supply and the recovered path of the to-be-recovered power supply; and 4, optimizing the power supply recovery sequences based on the artificial bee colony algorithm. According to the method, a universal mode for optimizing the power transmission route of a power grid containing the direct current convertor station is proposed; the optimization is realized based on the advantages of high rate of convergence and strong global searching capability of the artificial bee colony algorithm; and the optimization method is of great significance for a black-start scheme after blackouts.

Description

technical field [0001] The invention belongs to the field of power system analysis and control, in particular to an optimization method for power supply restoration path including DC converter station based on artificial bee colony algorithm. Background technique [0002] With the increasing scale of the power system and the advancement of the marketization process, my country has entered the development stage of large power grids, large power plants, large units, ultra-high voltage transmission, and high automatic control. Currently, North China Power Grid, Northeast Power Grid, Northwest Power Grid, East China Power Grid Power grids with regional characteristics, such as Central China Power Grid and China Southern Power Grid. The increasingly close connection between the power grids makes the operating conditions very complicated, and the uncertainties are also increasing. The grid accidents caused by human or natural factors may induce cascading failures, and even lead to ...
