Abstract
Low frequency oscillations (LFOs) have a dramatic
effect on small signal stability of a power system. As power
system started to operate near its stability limits, LFOs might
lead to system instability. Power system stabilizers (PSSs) are
provided with automatic voltage regulator to damp such effects.
In this paper, an interval type-2 fuzzy logic power system
stabilizer (IT2FLPSS) is proposed as a stability enhancements of
a single machine power system connected to the infinite bus. In
addition, a conventional power system stabilizer (CPSS) has been
introduced, both CPSS and IT2FLPSS results’ were compared at
different disturbance scenarios to show the improvements added
to the system when using IT2FLPSS. MATLAB/SIMULINK
programs are proposed to illustrate system performance at all
proposed scenarios.
