Advanced Technologies in Power Quality and Power Disturbance Data Application

<p><span style=color: rgba(23 43 77 1)>This Reprint compiles research from the closed Special Issue Symmetry in Advanced Technologies in Power Quality and Power Disturbance Data Application published in the journal </span><em style=color: rgba(23 43 77 1)>Symmetry</em><span style=color: rgba(23 43 77 1)>. It explores the electrical power system as a complex symmetrical network balancing supply and consumption emphasizing the critical role of power quality (PQ). Key PQ disturbances-including voltage sags harmonics transients and asymmetrical variations-are examined for their impact on system stability and end-user reliability. The volume addresses advanced methods for PQ monitoring mitigation and prevention highlighting the evolving challenge of analyzing these phenomena. Significantly it investigates how disturbances leveraged through power-related big data analytics can provide valuable insights into system health and equipment conditions transforming traditional PQ management into an opportunity for intelligent diagnostics.</span></p>
