Abstract

In this paper, the effect of the reactive power deviation (ΔQ) auxiliary signal on the classic power system stabilizers (PSS) with ΔP+ Δω inputs is studied and then the multi-input power system stabilizer (MPSS) with ΔW+ΔQ+ΔP inputs is investigated. Then, the effect of communication lines active power variance signal between two ΔP_Tie-line regions, as one of the inputs of fuzzy multi-input power system stabilizer (FMPSS), on the increase of low frequency oscillation damping is examined. The efficiency of the proposed model is examined by simulating a four-machine power system. Results show the model reduces the cost of system.
