“…The values of the system power factor are decreasing and the the total harmonic distortion for current (THDI) value is increasing [2][3][4][5]. Circuit elements with non-linear characteristics in the power electronics devices generate THDI [6][7]. Harmonic components injected from power electronics based devices cause resonance in the solar PV system.…”

Solar Photovoltaic (PV) energy is one of the main topics that have attracted the attention of researchers in recent years. The use of solar energy is increasing rapidly in the world. Although PV energy has many advantages, it has some disadvantages. Among these disadvantages, power factor (PF) and Total Harmonic Distortion (THD) issues are discussed in this article. PF and THD are dependent on the radiation values. The solar inverter output voltage and current waveform should be in sinusoidal waveform. However, the sinusoidal waveform of current and voltage lose their sinusoidal characteristics due to non-linear loads on grid-connected solar system. Harmonic components often occur in grid-connected solar PV systems. In addition, at low irradiance the amplitude of harmonic components increases, whereas the power factor of the PV system decreases. Low power factor and high amplitude of harmonics cause the efficiency of the solar system to decrease. PF and THD values were measured in a particular cloudy day for analysis. The grid-connected PV system was modeled by using Matlab /simulation program and carried out the analysis of the solar PV system. Thus, the analytical expression of the PF and THDI dependent on irradiation were found with a new method by using statistical package for the social sciences (SPSS) program and curve fitting method.

“…Through a detailed analysis of the effect of solar irradiance on the power quality behavior of a grid-connected PV system, the authors signified in [3] that low solar irradiance can significantly affect the output of a PV system, maintaining the power factor at a low level due to comparable production of active and reactive power. In addition, the influence on distribution grids of large-scale as well as on rooftop PV systems can be found in references [4,5].…”

Aware of the fact that the installed PV capacity and its power production rapidly increased in the last decade, with the huge impact that has been done to the power system, the distortion effects for grid-connected PV systems with reference to different types of electric power quantities will be presented in this article. The impact of the frequent fluctuation of solar irradiance on the behavior of the grid-connected PV system, due to cloud movements and resulting shadows and in terms of power quality and the evaluation of power components, is the topic of analysis in this research. Besides the simulation results of certain study cases, an experimental evaluation of electric power quantities on an actual PV system in real weather conditions was also performed. The experimental setup, formed through the combination of a PC and multifunctional I/O board with an appropriate software solution, was established and used for obtaining the target results. The methodology used for the evaluation of electric power quantities relied on the current physical components (CPC) theory for power definition. The experimental results were obtained for three different cases, namely, the low, medium, and high solar irradiance cases. On the basis of these results, the conclusions about distortion effects are given.

This paper describes detailed scrutiny of the main components contained in the system. There is a DC-DC converter that extracts the maximum amount from the photovoltaic generator. The interface inverter was developed to transfer energy from the PV module into the grid with constant common dc voltage. A 90MW PV system with a 3-phased framework linked is planned and reviewed. This system is a high-fidelity exemplary with power control in the inverters, DC-DC converters, DC-AC inverters, and three-phase service grids used as components designed and formed mathematically as a reproduction model. The model contains various components such as the boost converter, the PV control modes, the inverter, and the framework utility. The essence of the reactive power generation in the PV inverter is represented. The components are modelled physically to generate high-fidelity simulation. Active and reactive power measurements are accurately taken and analysed. The study of the PQ controller is presented in the framework connection control of the system. The simulation results obtained in the modelling process show an effective power-controlled model.
