6 FAQs about [Photovoltaic inverter current adjustment]

How Ann control a PV inverter?

Figure 12 shows the control of the PV inverters with ANN, in which the internal current control loop is realized by a neural network. The current reference is generated by an external power loop, and the ANN controller adjusts the actual feedback current to follow the reference current. Figure 12.

What is constant power control in a PV inverter?

In general, PV inverters’ control can be typically divided into constant power control, constant voltage and frequency control, droop control, etc. . Of these, constant power control is primarily utilized in grid-connected inverters to control the active and reactive power generated by the PV system .

How do PV inverters control stability?

The control performance and stability of inverters severely affect the PV system, and lots of works have explored how to analyze and improve PV inverters’ control stability . In general, PV inverters’ control can be typically divided into constant power control, constant voltage and frequency control, droop control, etc. .

How to provide voltage support in PV inverter?

To provide voltage support at the PCC, reactive power is injected into the grid under fault conditions as per the specified grid codes. As previously discussed, the simultaneous injection of peak active power from PVs and reactive power into the grid for voltage support can trigger the over current protection mechanism in PV inverter.

What is the control performance of PV inverters?

The control performance of PV inverters determines the system’s stability and reliability. Conventional control is the foundation for intelligent optimization of grid-connected PV systems. Therefore, a brief overview of these typical controls should be given to lay the theoretical foundation of further contents.

What is over current protection mechanism in PV inverter?

As previously discussed, the simultaneous injection of peak active power from PVs and reactive power into the grid for voltage support can trigger the over current protection mechanism in PV inverter. The triggering of over current protection will lead to disconnection of inverter from the grid which is unfavourable during LVRT period.
