PSO based OPF algorithm

Nowadays there is a huge interest in developing new approaches for power system related problem solving. Generally, (meta)heuristic search methods are considered a good alternative to conventional ones. This paper aims to elaborate an original mathematical model focused on particle swarm optimization (PSO) applied for optimal power flow computing (OPF). Several practical issues are presented. One test power system is used as case study. Additionally, the algorithm developed is also applied for a real power system. It refers to the Western and South-Western side of the Romanian Power System. Further, it is intended to be used for transmission expansion planning.
