Can LVRT test identify the parameters of a PV inverter?
In the case that the PV inverter control strategy and parameters are not disclosed, a method is proposed to realise the identification of the three types of parameters through the LVRT test. The method can solve the difficulty in performing the tests of Groups 2 and 3 parameters in the field.
What is a photovoltaic (PV) panel?
The solar panel or PhotoVoltaic (PV) panel, as it is more commonly called, is a DC source with a non-linear V vs I characteristics. A variety of power topologies are used to condition power from the PV source so that it can be used in variety of applications such as to feed power into the grid (PV inverter) and charge batteries.
How does a PV inverter state machine work?
The inverter state machine then sequences to checking for DC voltage. To feed current into the grid the DC voltage (which in case of PV inverters is provided from the panel or panel plus some conditioning circuit), it must be greater than the peak of the AC voltage connected at the output of the inverter.
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.
