6 FAQs about [Does the photovoltaic inverter have negative impedance characteristics ]
What is a passive equivalent impedance network of PV inverter?
Based on impedance model of two-stage PV inverter in frequency domain, the passive equivalent impedance network of PV inverter connected to power grid is built.
Do PV inverters have stability problems on weak grid condition?
The corresponding equivalent grid impedance is rather large and easy to lead to stability problems of grid-connected inverters and many researches have been done focusing on the stability problems. In this study, a survey of stability problems of PV inverters on weak grid condition is given.
Why does a PV inverter have a series parallel resonance?
When the PV inverter is connected to the grid, series–parallel resonance may occur due to the dynamic interaction between multiple inverters operating in parallel and between the PV inverter and the grid impedance. Consequently, this leads to changes in the output voltage harmonic characteristics of the PV plant.
Does grid impedance affect inverter output voltage?
Previous contents have explained the influence of grid impedance on inverter current control loop and dc-link stability but have not considered the influence of grid impedance on inverter output voltage, especially when the grid impedance becomes large due to the parallel structure in large PV plants.
Are inverters connected to a weak power grid?
With the development of PV generation, more and more inverters are connected into the power grid to supply power for users. The grid impedance then becomes large and brings serious challenges to inverter's stability [1 - 7]. This paper focuses on the stability problems when inverters are connected into weak power grid.
Why does PV inverter output voltage contain high order harmonics?
According to the previous analysis, the increase of the PV inverter output power may cause PV output voltage to contain high order harmonics under the weak grid, which are mainly distributed near the resonance peak of output filter LCL of PV inverter.
