“…In Ref. [13], the authors conducted field tests on a smart PV inverter, and determined that the current harmonic amplitudes (in Ampere) are essentially independent of solar irradiance, nor when activating of some of its advanced functionalities such as non-unity power factor operation and Volt/VAR control. Additionally, the harmonic current components are founded to be affected by the background harmonic components of the voltage supply.…”

Recent advances in grid-tied photovoltaic inverters are allowing more flexibility including Volt/VAR control, variable power factor operation, and adjustable ride-through capability. Some new inverters can now operate in stand-alone mode in case of a power outage during the daylight hours. Inverters are also known to supply currents that are highly distorted when operating under low solar irradiance. This paper evaluates how such distortion varies with the power produced by a modern single-phase PV inverter through field measurements. Additionally, the quality of its supply voltage, when operating off-grid, is analyzed in terms of its harmonic content under different loading conditions.

“…FV-DÜB'lerin akım harmonik bozulma karakteristiğini analiz eden birçok çalışma literatürde mevcuttur [29][30][31]. Bu çalışmalardan, FV-DÜB'lerin şebekeye enjekte ettiği harmonik akımlarının temel frekans akımına göre bağıl değerlerinin Güneş ışınımıyla ters orantılı ilişkiye sahip olduğu bir başka ifadeyle düşük Güneş ışınımı değerlerinde daha fazla harmonik bozulmaya yol açtığı görülmektedir.…”

In today's power systems, the use of distributed generation units has become widespread in order to improve the voltage profile, increase system reliability, reduce line losses and increase energy efficiency. Among these distributed generation units, wind turbines and photovoltaic units have limited the use of traditional energy sources such as natural gas, coal and oil in electricity generation, thus they became important options for the prevention of environmental problems such as greenhouse gas emissions and global warming. However, these distributed generation units are connected to the grid via power electronics circuits and their energy sources are non-dispatchable. Thus, they lead to various power quality problems in the power systems. In this study, firstly, the latest technological case of the photovoltaic distributed generation units (PV-DGUs) is presented. Secondly, the power quality problems caused by PV-DGUs in the power systems and the international power quality standards related with the systems containing PV-DGUs are investigated. Finally, the power quality mitigation methods have been detailed for the systems with PV-DGUs.
