Technical FAQs 4

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 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.

What is P control in a PV inverter?

P control adjusts the output proportionally to the error signal, which represents the difference between the desired setpoint (e.g., target voltage or current) and the current system value. P control gives a quick response to the deviations and is employed for voltage and current regulation in PV inverters 16.

How do inverters affect a grid-connected PV system?

For a grid-connected PV system, inverters are the crucial part required to convert dc power from solar arrays to ac power transported into the power grid. 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 .
