Dynamic Stability Improvement of Multimachine Power Systems using ANFIS-based Power System Stabilizer
Abstract: Modern power system
are very vurnerable to against load fluctuation during their operation. Load fluctuation
is identified as small disturbance that it is very important in small signal
stability (dynamic stability) testing. This research consisted of large scale
power system symplification. And, ANFIS-based power system stabilizer (AP) is
proposed to improve the dynamic stability of multimachine. The ANFIS method is
proposed because the ANFIS computation is more efective than Mamdani fuzzy
computation. Simulation results show that the proposed PSS is able to maintain
the dynamic stability by decreasing peak overshoot to the value 3,37 10 5 pu and accelerating settling time to the time 4.01 s for rotor
speed deviation of Machine-2. Also, the peak overshoot is decreased to
the value 1,34 10 5 pu and the settling time is accelerated to the time 3.98 s
for rotor speed deviation of Machine-3.
