Abstract

This paper conducts a comprehensive analysis of Power Quality (PQ) variations correlated with solar irradiance, emphasizing their significance in a 62.4 kWp PV grid-connected system. Installed in 2021 at the Libyan Center for Solar Energy Research and Studies (LCSERS) in Tajura, Libya (Latitude 32.81°N, Longitude 13.43°E), the system features a 50 kW SMA Core One inverter and serves as a car park. Given the inherent instability in Libya's public network, a thorough examination of the impact of these systems becomes imperative. The primary focus of this study is the critical analysis of PQ parameters, encompassing voltage, current, frequency, active and reactive power, power factor, harmonics distortion, and solar irradiance variations. The analysis is further compared with international standards, such as Institute of Electrical and Electronics Engineers (IEEE). The findings reveal a substantial correlation between PQ variations and PV power output, presenting a potential series threat to future distribution networks.
This paper offers valuable insights into understanding the implications of Power Quality variations in photovoltaic systems, particularly in regions with unstable public networks. The identified strong relationship between PQ variations and PV power output underscores the necessity of addressing these issues for the sustainable integration of solar energy into distribution networks
