Transmission Network Expansion Planning Using Artificial Fish Swarm Algorithm

This MATLAB .m file implements transmission network expansion planning based on the Artificial Fish Swarm Algorithm (AFSA) using the IEEE 6-node system model. The implementation includes key subroutines for power flow calculation, overload assessment, main algorithm program for the six-node system, foraging and tail-chasing behavior simulation, algorithm parameter definition and configuration, parameter assignment routines, and line parameter reading modules. The code structure follows AFSA's collective intelligence approach where artificial fish agents optimize network expansion through simulated behaviors.
