6 FAQs about [Principle of Photovoltaic Inverter Power Limitation]

How does a PV inverter limit AC output?

In times of optimal performance, the inverter limits the AC output by controlling the voltage and current. This means that the PV power is curtailed by the inverter . Curtailment of PV power at the feed-in point may be necessary to match supply and demand within the grid.

How to reduce the voltage limit of a photovoltaic inverter?

In the literature [7, 8], it proposes to reduce the voltage limit by reducing the output active power of the inverter. Although this method can effectively solve the problem of dot voltage limit, it increases the photovoltaic discard rate.

What is the use of bus voltage in a photovoltaic inverter?

The increase in bus voltage is used as the control signal of the PV output current to reduce the photovoltaic output current, such that the PV output power is reduced from 3000 W to the inverter power limit value of 1500 W, which meets the requirements of the inverter output power limit.

Can a PV inverter reduce the power output?

This is quite possible, as PV systems often produce less than their rated power. In times of optimal performance, the inverter limits the AC output by controlling the voltage and current. This means that the PV power is curtailed by the 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 .

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. .
