研究目的
Investigating the impacts of photovoltaic system integration in the low voltage power grid of a university building in Colombia.
研究成果
The study demonstrated the reliability of measured data from the PV system and highlighted the need for compliance with Std. IEEE 1547-2018 recommendations for THDv and harmonic distortions. It also identified under-voltage violations and high penetration of certain harmonics, suggesting areas for further investigation and system optimization.
研究不足
The study was limited to a specific university building's electrical network and a 32-day monitoring period. The presence of high harmonic distortions and the need for more frequent data logging for comprehensive impact assessment were identified as areas for optimization.
1：Experimental Design and Method Selection:
The study involved monitoring electrical variables (voltages, frequency, active power, voltage distortion, and harmonics) at the Point of Common Coupling (PCC) to assess the impact of PV system integration.
2：Sample Selection and Data Sources:
The study focused on the LV electrical network of a university building with a
3：1 kW PV system. Solar irradiation data was measured on-site, and electrical variables were recorded using a smart meter. List of Experimental Equipment and Materials:
A KIP & ZONEN SMP3 pyranometer for solar irradiation measurement and an Acuvim IIR smart meter for electrical variables.
4：Experimental Procedures and Operational Workflow:
Data was recorded every 10 minutes for 32 days to evaluate the PV system's impact on the electrical network.
5：Data Analysis Methods:
The analysis included evaluating voltage deviations, frequency stability, and harmonic distortions against Std. IEEE 1547-2018 recommendations.
