Abstract

Abstract Recently, Power Quality (PQ) issues have emerged to be acritical problem faced by the distributed power system on account of its several forms and frequencies of occurrence. Thereby, the integration of the distributed generation of Photovoltaic (PV) with Unified Power Quality Conditioner (UPQC) is recommended in this work with the intension towards improvement of quality of power delivered to the customers. Also leading to the development of a novel grid tied PV design that avoids any unfavourable voltage or current situation in distributed power system. The series compensator of the UPQC addresses voltage-related challenges, while the shunt compensator of the UPQC handles current-related challenges. The interfacing of the PV to the UPQC is accomplished using the Cuk Integrated Boost Converter (CIBC)and the optimum extraction of PV power is ensured with the application of Cascaded Type-2 Fuzzy Logic Controller (CT2FLC) based Maximum Power Point Tracking (MPPT) technique. The control of the UPQC is done using Fuzzy tuned Adaptive PI controller in addition to Convolution Neural Network (CNN) assisted DQ theory. The dynamic nature of the presented approach in terms of compensation capability and dc-bus stability is assessed through MATLAB simulation and experimental verification.
