Research ArticleOpen accessIn the author namesDecentralized Controller Design for Static Synchronous Compensator Using Robust Quantitative Feedback Theory MethodSeyed Abbas Taher, Reza Hematti, Ali Abdolalipour, Majid NematiThe Static Synchronous Compensator (STATCOM) provides shunt compensation in similar way to the Static VAR Compensator (SVC) but utilizes a voltage source converter rather than capacitors and reactor. In practice systems use simple Proportional-Integral (PI) controllers for control of STATCOM. However, since the PI control parameters were usually tuned based on classical or trial-and-error approaches, they were incapable of obtaining … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 1 · 31 Mar 2008 · 7,461 accessesView PDF Cite

Research ArticleOpen accessIn the author namesComparison of Different Control Strategies in GA-Based Optimized UPFC Controller in Electric Power SystemsSeyed Abbas Taher, Reza Hematti, Majid NematiThis study presents a study of the application of a Unified Power Flow Controller (UPFC) to control power transmission, generator terminals voltage and better damping of Low Frequency Oscillation (LFO) in Single-Machine Infinite-Bus (SMIB) power system. The UPFC integrates properties of both shunt and series compensations and can effectively alter power system parameters in a way that increases power transfer … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 1 · 31 Mar 2008 · 7,606 accessesView PDF Cite
