Transient Stability Enhancement by Optimal Location and Tuning of STATCOM Using PSO

Transient stability enhancement via optimal location and tuning of STATCOM is thoroughly investigated in this paper. The performance analysis of STATCOM has been executed for Western Science Coordinated Council (WSCC) 9 bus system for the enhancement of transient stability using Power System Analysis tool box (PSAT) software. The proposed Particle Swarm Optimization (PSO) algorithm technique, location of the STATCOM device and parameter value is optimized simultaneously. The performance of STATCOM (Static synchronous Compensator) is implemented through the nonlinear time-domain simulation. The results are compared with the Particle Swarm optimization based tuned STATCOM. The proposed algorithm is very effective and analyzed using PSAT software.
