On the optimal tuning of FACTS based stabilizers for dynamic stability enhancement in multimachine power systems
This paper presents a systematic method of developing the mathematical model for small signal stability enhancement in multi machine power systems using different types of FACTS devices namely (i) SVC (ii)STATCOM (iii) TCSC (iv) SSSC and (v) UPFC. Two axis model of the synchronous machine is used for investigating the small signal dynamic behavior of the multimachine power system. Local stabilizing signals such as real power perturbations, bus voltage deviations are used as control inputs for the damping controllers in FACTS devices. A nonlinear optimization model is developed which tunes the gains, time constants of the FACTS based damping controllers in the stabilizing loop. Case studies are carried out on the standard WSCC 3 Machine 9 − Bus system and the 10 Machine, 39 bus New England system. All computations are carried out using MATLAB v7.6.
