Coordinated control and parameters optimization for PSS, POD and SVC to enhance the transient stability with the integration of DFIG based wind power systems

Abstract This paper presents stability enhancement of a test system that is connected with Wind Farm (WF) by using Power System Stabilizer (PSS) for Synchronous Generator (SG) and Oscillation Damper (POD) Static Var Compensator (SVC). also proposes coordination mechanism the controller to effectively damp out oscillations make power more stable considering uncertainties. The uncertainty considered as wind speed variation penetration different locations. Particle Swarm Optimization (PSO) used overcome parameter tuning drawbacks coordination. SG rotor deviation selected an objective function various constraints PSO. transient analysis carried large disturbance three-phase fault. nonlinear dynamic simulation results are obtained integrating WF replacement same rating WF. Evaluation performed cases combination without controllers. From results, it noticed in minimized, enhanced at maximum level. It observed capability DFIG under fault intensified PSO optimized coordinated parameters. robustness effectiveness proposed approaches evaluated on IEEE-11 bus system.
