Technical FAQs 4

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 .

What are the output F/V characteristics of an inverter?

The output F/V characteristics of the inverter, that is, the load torque output mode, are basically divided into two types: a constant relationship (corresponding to constant torque mode) and an exponential relationship (corresponding to the fan-type load mode), not divided into constant power and constant torque.

How do PV inverters work?

Traditionally, PV inverters work in grid-following mode to output the maximum amount of power by controlling the output current. However, grid-forming inverters can support system voltage and frequency and play an important role in weak power grids. Inverters with two operation modes are attracting more attention.

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.
