Abstract: “In a deregulated electricity marketcongestion management of the transmission network is an essential task of an Independent System Operator (ISO).A congested transmission network threatens the safe and secure operation of a power system and reduces the competitiveness and efficiency of the electricity market. In this paper, an OPF based congestion management procedure has been discussed and Catfish Particle Swarm Optimization (C-PSO) has been utilized to manage the congestion. The proposed C-PSO based algorithm has been implemented on an IEEE 30-bus system and compared with the basic PSO based algorithm. The results have shown that the C-PSO based congestion management gives better results as compared to PSO based congestion management.”
