Abstract

Deregulation of electric power industry aims at creating a competitive market and this brings in new challenges in the technical and non technical aspects. One such problem is congestion management which involves relieving the transmission lines off their overloads, which in other words means enhancing the Available Transfer Capacity of the lines (ATC). In this paper the problem of enhancing the transfer capacity of the transmission lines is addressed by installing TCSC’S through the application of one of the variants of the popular Meta heuristic search technique, Particle Swarm Optimization (PSO) namely Weight Improved Particle Swarm Optimization (WIPSO). The problem is solved by taking into account the variations in wheeling transactions across any two selected buses and the algorithm is used for enhancing the ATC under various load conditions in an emission economic dispatch environment and the results are compared against those obtained using PSO.
