Abstract

Abstract: A Harris Hawks Optimization (HHO)tuned dual interval type-2 fuzzy lead–lag (Dual-IT2FLL) based unified power flow controller (UPFC) is proposed to minimize oscillations in single and multimachine power systems. The proposed damping controller coordinates between the modulation index (MI) and phase angle of series and shunt converters of UPFC simultaneously and is designed using speed deviation, a remote input signal for stability improvement. The performance of the proposed controller is verified through nonlinear time and frequency domain simulations under different operating conditions. The graphical simulations and validations using OPAL-RT OP5600 are presented to access the stability performance. Comparison based on different performance indices (PIs), like mean, standard deviation, overshoots and settling time are also considered to prove the better performance of the proposed HHO tuned dual-IT2FLL based UPFC over others under different operating conditions. Highlights: Application of robust dual-IT2FLL based UPFC for minimizing LFOs. Optimal selection of controller's parameters using HHO. Analysis of HHO tuned dual-IT2FLL based UPFC using time and frequency domain simulations. Comparative analysis between the controllers using performance indices. Real-time analysis using OPAL-RT to augment the stability study.
