6 FAQs about [Photovoltaic inverter electrical parameter representation]

What are the reference values for a PV inverter?

The reference values of the active and reactive currents can be expressed as follows: PDC−VDC curves with r = 0 Ω and r = 0.042 Ω, respectively. In the failure mode, the PV inverter operates at point G1 (actual operating point) when r = 0.042 Ω, and the DC voltage rises by 111 V.

Can LVRT test identify the parameters of a PV inverter?

How does R affect the DC voltage of a PV inverter?

The PV inverter operates at G 2 when r = 0 Ω, and the DC voltage rises by 98 V. A noticeable difference of 11.7% exists between the two operating points. Therefore, the influence of r should be considered in the LVRT process to accurately model the dynamic behaviours of the DC voltage.

What are the environmental parameters of PV arrays?

Environmental parameters of the PV arrays The expectancy value of r is set as 0.03 Ω in the simulation model to make the set value applicable to various dip levels. After that, S and T can be solved under different test conditions based on the accurate modelling of point M first.

Can a PV array accurately simulate the dynamic process of DC voltage?
