Comprehensive Monitoring Strategies for Photovoltaic System Integration
This white paper examines the unique power quality and grid stability challenges introduced by photovoltaic (PV) systems, emphasizing the need for detailed monitoring of voltage, current, real/reactive power, and harmonics. It provides practical recommendations for configuring power quality (PQ) recorders, stripcharts, and waveform capture to address both immediate operational issues and long-term planning needs. The findings highlight how dynamic PV output, inverter characteristics, and local loads can impact system performance, and how targeted data collection can support effective regulation and system optimization.
Key topics include:
- Issues with PV Systems
- PV Stripchart Recommendations
- Voltage, Current, and Harmonic Monitoring
- Waveform Capture Recommendations
- Case Studies and Data Interpretation
Why utilities should care:
Effective PV monitoring enables proactive identification of power quality issues, supports optimal voltage and VAR regulation, and ensures reliable integration of distributed generation. Comprehensive data collection informs system planning, enhances operational stability, and mitigates grid disturbances.
