6 FAQs about [Voltage distortion of photovoltaic inverter]

Do photovoltaic inverters cause harmonic distortion?

The increasing penetration of photovoltaic (PV) systems, consisting of PV panel and PV inverter, may introduce power quality issues to the distribution power system. One critical concern is the harmonic distortion. This paper proposes an analytical harmonic model of PV inverters to assess its harmonic impacts on the distribution systems.

What is the Distortion limit of a PV inverter?

According to the standards, the distortion limit of the odd harmonics orders three, five, seven, nine and eleven must be less than 4% when the inverter is operating at nominal power. The currents and voltages harmonics components analyzed and compared at 10% and 70% of relative power for two different operation modes of the PV inverter.

Does a PV inverter have a harmonic impact on distribution systems?

This paper proposes an analytical harmonic model of PV inverters to assess its harmonic impacts on the distribution systems. The model is also verified by both simulation and laboratory experimental results. The proposed model indicates that the PV inverter has both harmonic source characteristic and harmonic impedance characteristic.

Can a PV system cause voltage distortion?

However, utility standards and manufacturers’ data sheets are only concerned with the full-load condition. PV systems incorporate power electronic interfaces, which generate a level of harmonics [ 5 ], potentially causing current and voltage distortions.

What is the relationship between voltage and current harmonics of PV inverter?

Voltage and current harmonics at PF = Unity. Detailed evaluation of the measurement results has been carried out in order to highlight the relationships between the harmonic currents of PV inverter and the harmonic voltages prevailing in the LV system. Again, different classes of the generated power have been set up in function of the P/Pr ratio.

What causes voltage harmonics at the inverter output?

The voltage harmonics at the inverter output are due to fifth and seventh harmonics at capacitive 0.95 power factor, since the remaining harmonics have values less than 0.5% VRMS as shown in Fig. 15 (c) and (d).
