Robust and Effective Tuning of FACTS-PODs of Interconnected Systems Using Harmony Search Algorithm

This paper presents the Harmonic Search Algorithm (HSA) and Teaching-Learning-Based Optimization (TLBO) that are used to solve the tuning parameters of Proportional and Integral (PI) of the Power Oscillation Damping (POD) with Power System Stabilizer (PSS) which controller the Static Var Compensator (SVC) device. The fast acting of the SVC is able of improving both the steady state operation and overall performance of the networks to reach stabilization. The proposed system based on HSA and TLBO have been tested on IEEE 9 test system with SVC device. The approach system is compared with SVC only and traditional PI-POD. The parameters of traditional PI are adjusting by try and error method. The simulations results show the effectiveness of the proposed system in term of transient stability, damping oscillation and steady state operations as compared with other methods.
