6 FAQs about [Photovoltaic inverter automatic operation]

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 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 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 intelligent is a PV inverter system?

Although various intelligent technologies have been used in a PV inverter system, the intelligence of the whole system is still at a rather low level. The intelligent methods are mainly utilized together with the traditional controllers to improve the system control speed and reliability.

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.

How does a PV inverter work?

In this manner, the PV inverter operates similar to a fixed reactor bank, which, when switched on, provides a fixed amount of reactive power based on the reactive power capabaility de-signed for the bank. However, the PV inverter will continue to also inject a set amount of active power based on the current load of the system.
