6 FAQs about [Regulation of photovoltaic inverter]

Are PV inverters voltage regulated?

In the modern day, the PV inverters are being developed under the interconnection standards such as IEEE 1547, which do not allow for voltage regulations . However, a majority of manufacturers of PV inverters tend to enhance their products with reactive power absorbing or injecting capabilities without exceeding their voltage ratings.

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. .

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.

How a PV inverter control the voltage of a PCC?

In this control strategy, the voltage of PCC is tracked by PV system in real time. When the voltage of PCC is normal, inverter will output in the way of maximum power point tracking (MPPT).When the voltage of PCC exceeds the upper limit, the inverter will regulate the voltage using the remaining capacity preferentially.

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 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 .
