Problems solved by technology

[0003] At present, there are many distribution network reconfiguration methods, such as the branch exchange method and the optimal flow mode method. Heuristic rules, lack of global optimality in the mathematical sense, tend to converge to local optimal solutions
Among the artificial intelligence algorithms widely used in distribution network reconfiguration, the genetic algorithm has a slow convergence speed and poor local optimization ability; the global optimization ability of the tabu search method is greatly affected by the length of the tabu; the calculation time of the ant colony algorithm is long

Embodiment Construction

[0037] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0038] The distribution network generally adopts a closed-loop design and an open-loop operation method. The distribution network contains a large number of normally closed section switches and a small number of normally open contact switches. When the load changes or a fault occurs, it is necessary to change the opening and closing state of the switch in time to reconstruct the network and isolate the fault. Such as figure 1 As shown, the present invention discloses a distribution network reconfiguration method based on the fireworks algorithm. The fireworks algorithm was first proposed by Professor Tan Ying of Peking University in 2010. It has been tested and verified to have a faster convergence speed and global optimization ability. This application is a distribution network reconfiguration scheme explored and estab...

Abstract

The invention relates to a power distribution network reconstruction method based on a fireworks algorithm. The power distribution network reconstruction method comprises the following steps: independently taking network losses, load balance and voltage decreasing amplitude as bases to define a target function; determining an integrative objective function of the safe operation of a power grid; adding a constraint condition for the integrative objective function; and adopting a firework explosion search mechanism to reconstruct the power distribution network and isolate faults when the load of the power distribution network is changed or the power distribution network fails. The method can quickly improve an optimization direction, effectively avoids acceleration and can easily obtain a global optimal solution.

Description

technical field [0001] The invention belongs to the technical field of distribution network reconfiguration, and in particular relates to a distribution network reconfiguration method based on fireworks algorithm. Background technique [0002] For flexible and reliable power supply, the distribution network generally adopts closed-loop design and open-loop operation. The distribution network contains a large number of normally closed section switches and a small number of normally open contact switches. When the load changes or a fault occurs, it is necessary to change the opening and closing state of the switch in time to reconfigure the network, isolate the fault, improve the voltage distribution, and ensure the safe and economical operation of the distribution network. [0003] At present, there are many distribution network reconfiguration methods, such as the branch exchange method and the optimal flow mode method. Heuristic rules lack global optimality in the mathemat...
