Advancing Power Quality in Smart Grids Through Tailored UPQC Modifications

In the realm of fortifying security measures and enhancing Power Quality (PQ) within the intricate landscape of the Smart Grid (SG) infrastructure, this investigation delves into the intricate harmonic's conundrum induced by the pervasive utilization of power electronic devices. While (UPQC) Unified Power Quality Conditioners are conventionally employed to ameliorate voltage-related challenges in distribution systems, paradoxically, they introduce harmonics that impinge on system stability, especially concerning delicate loads. This research introduces an inventive methodology that fuses bio- geography-based optimization and harmonics elimination techniques into a tailored UPQC integrated within the SG framework. Lower-order harmonics are assuaged through judiciously calculated switching angles, whereas higher order harmonics are quelled by infusing harmonics of identical order, yet possessing equal magnitude and opposing phase, emanating from the alternate converter. The induction of Photo-Voltaic (PV) panels to energize the adapted UPQC converters ensures a sustainable power source, and real-time firing angles are extrapolated from pre-archived values stored in the microcontroller memory. This comprehensive approach not only confronts the intricacies of UPQC-associated harmonics but also seamlessly integrates renewable energy sources, ushering in a new era of efficiency and sustainability in Smart Grid operations.
