This article presents the design of unified power flow controller (UPFC) damping controllers based on Proportional-Derivative (PD)-type lead-lag (PD type LL) controllers for dampening low-frequency oscillations in a power system. The proposed PD type Lead Lag based UPFC uses hybridized of Whale and Moth-Flame Optimization Algorithms (WMFOA) to tune controller parameters is compared with MFO, WMFOA, and particle swarm optimization (PSO) tuned controllers for damping low frequency oscilliations. The eigenvalue analysis of time domain simulation has been demonstrated to show the effectiveness of transient stability improvement of PD type LL UPFC controller of the power system. The results analysis reveals that hybridizing of WMFOA tuned WMFOA PD type LL UPFC has excellent capability in damping power system low-frequency oscillations. The same test model type-2 fuzzy lead-lag-based UPFC damping controller transient stability improvement performance is compared to PD type LL controller of the same power system. It is demonstrated with four alternative control signal-based UPFC damping controllers are evaluated under a variety of disturbances and variation of parameters of the power system. The damping function of the UPFC with various alternative control signals is investigated using a linearized modified Phillips–Heffron model of a power system with a UPFC controller implemented.
