Nowadays, Power Quality (PQ) problems are economically affecting customers and utilities. In our work, the PQ problems are mitigated using the Unified Power Quality Conditioner (UPQC) and the proposed controller. Fuzzy Logic Controller (FLC) and Emperor Penguin Optimization algorithm (EPO) are utilized to design the proposed controller. The proposed control scheme analyses the PQ issues of harmonics, oscillatory transients, swell, and voltage sag. The optimized FLC controller-based UPQC compensates the PQ problems at a common coupling point. Using the decomposition technique, the Total Harmonic Distortion (THD) and harmonics are moderated, and the voltages sag and swell problem is minimized to improve the compensation capability. The MATLAB/SIMULINK platform is utilized to evaluate the performances of PQ issues in UPQC compensating devices. The generated, injected, and load voltages results are compared with existing controller techniques.
