Modeling and performance analysis of the UPQC integrated power system using an innovative controller combination

Maintaining the quality of electric power in multi-bus systems is always a challenging chore, because of loads with nonlinear characteristics. Integrating the FACTS devices is the better solution for power system stability. The Unified Power Flow Conditioner (UPQC) is employed in power distribution systems to mitigate Power Quality (PQ) issues associated with voltage and current fluctuations. This paper outlines the design and performance evaluation of the unified power-quality conditioner (UPQC) integrated into the IEEE 14 bus test system. Typically, the UPQC configuration comprises two back-to-back converters controlled by a single controller. A novel combination of two various controllers is separately introduced in this paper. Furthermore, this paper highlights comparing the power quality performance like current harmonic elimination indices and voltage compensation using UPQC with FLC and ANN-based controller schemes. The proposed study's test system is modeled and simulated through MATLAB/SIMULINK
