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.
