Abstract

The invention discloses a power transmission network topology structure design method based on particle swarm optimization. The power transmission network topology structure design method comprises the following steps: (1) setting parameters; (2) initializing swarms; (3) generating a novel individual; (4) generating novel individual optimum and global optimum; (5) generating a novel swarm; (6) judging the present iteration times, if the maximum iteration times are met, executing step (7), or else executing step (3); (7) outputting an optimal power transmission network. In the process that a power transmission network topology structure is designed, the network robustness is taken as the individual evaluation standard, effective operation such as encoding, individual operator updating and domain swarm self-generation are designed, a particle swarm optimization frame is adopted, and the power transmission network topology structure with high robustness can be designed.

Description

technical field

[0001] The present invention belongs to the technical field of physics, and further relates to a method for designing a topology structure of an electric power transportation network based on a particle swarm optimization (PSO) algorithm in the technical field of physical network design. The invention can be used to design the topological structure of the electric power transportation network, so that when it is attacked or disturbed, the functions of the electric power transportation network can be kept intact to the greatest extent, and the attacked or disturbed can be effectively resisted. Background technique

[0002] Network robustness (Network robustness) is an important attribute of the network. It refers to a measure of whether the network can maintain perfect functions or continue to work when it is attacked, damaged or disturbed. In the power transportation system, power stations, substations, etc. are abstracted into complex network nodes, and tran...
