Recently, genetic algorithms (GA) and particle swarm optimization (PSO) technique have attracted considerable attention among various modern heuristic optimization techniques. Since the two approaches are supposed to find a solution to a given objective function but employ different strategies and computational effort, it is appropriate to compare their performance. This paper presents the appl...

Series compensation of transmission lines increase the risk Sub-Synchronous Resonance (SSR) problems. Use Thyristor Controlled Compensators (TCSC) in place Fixed Capacitors (FSC) has benefited terms damping SSR. SSR Damping with TCSC can be achieved supplementary controls or through its inherent capability. discrete time models for small signal stability analysis is well established. This paper...

In the emerging deregulated electric power market, congestion management becomes extremely important and it can impose barrier to electric power trading. There are t w o types of congestion management methodologies to relieve congestion in transmission lines. One is non-cost free methods and another is cost-free methods, among them later method relieves the congestion technically whereas the fo...
