Abstract

"Research Area: This research is grounded in power systems engineering and renewable energy integration; it specifically addresses power quality (PQ) issues in rapidly growing grids. As the capacity transitioned from 15 MW of renewable energy in 2000 to 9,200 MW in 2023, controlling grid stability and quality has become a national priority. Objectives: The overall goal is to carry out a long-term analysis of renewable energy integration's impact on Bangladesh's PQ. This research examines how the strategic dispatch of mitigation technologies (e.g., harmonic filters, STATCOM/SVC devices, and smart grid infrastructure) has resolved problems with total harmonic distortion (THD), voltage variations, and customer complaints. Methodology: This work combines and analyzes longitudinal data (2000–2023) from BPDB, PGCB, SREDA, IDCOL, ADB, and JICA. The key variables of THD, voltage deviations, PQ complaints, grid investments, and renewable curtailment are investigated. Key metrics were statistically analyzed using pandas and matplotlib, both Python-based tools. We examine the parameters of renewable capacity, THD, voltage deviation percentages, and the number of different mitigation technologies employed. Technology impact trends are revealed via descriptive and correlation analysis and case studies. This research is critical for nations facing similar transitions, showing how targeted technological interventions and investments in power quality management can be sustained in renewable-heavy grids. Analysis and Results: Results indicate that THD dropped from 8.7% to 7.0%, voltage fluctuations fell by 57%, and PQ complaints were reduced by 63%. These improvements are, in turn, associated with deploying 1,280 harmonic filters, 42 STATCOM/SVC units, and $1.95 billion in grid modernization. "
