| description | To increase the lifetime and performance of equipment in utility distribution systems, the enhancement of power quality is essential. In this paper, to enhance the power quality, we present the design of a hybrid fuzzy back-propagation control scheme for a unified power quality Conditioner. The gating pulses of the UPQC are generated using hybrid fuzzy-back propagation controllers. The reference currents for the controller are estimated using back-propagation algorithms with source currents and load currents as input control parameters. The reference voltages for the controllers are estimated using fuzzy logic controllers for the dc voltage regulator with a terminal voltage, and a dc voltage for the input control parameters. We perform this analysis in zero-voltage regulation mode and power factor correction mode in a multilevel UPQC-connected distribution system. We analyze the results of the total harmonic distortion, dynamic performance, load balancing and mitigation of the voltage sag using MATLAB/Simulink. Keywords: Hybrid fuzzy-back propagation control, Power quality, Voltage sag mitigation, Total harmonic distortion, Cascaded H-bridge inverter, UPQC, Load balancing |
