ABSTRACT

      Power quality (PQ) concerns are a major challenge for utilities, businesses, and consumers, as poor PQ can result in substantial financial losses. Addressing these issues is crucial to mitigating economic damage across industries and national economies. The financial burden of inadequate PQ is significant and continues to escalate, affecting even industries with minimal technological dependence. On a global scale, poor PQ has caused immense economic disruptions; for example, Indian industries suffered losses exceeding $9.6 billion due to power failures in 2008-09, while European enterprises faced annual financial setbacks surpassing $150 billion, as per 2008 estimates. This study presents an extensive analysis of PQ-related challenges encountered by consumers worldwide and highlights the economic repercussions of deteriorating PQ. Given its far-reaching financial consequences, the study underscores the importance of proactive engagement by energy providers, regulatory authorities, and end users to ensure consistent power quality. Additionally, it introduces an advanced power quality monitoring framework capable of identifying PQ disturbances and enabling effective mitigation strategies—an essential step toward enhancing smart grid infrastructure.
