Free QuoteFor 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 .
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 .
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. .
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.
Reactive power is required to increase the electrical grid's capacity. Consequently, a PV inverter providing reactive power is necessary. A PV power system that is currently in use needs a dependable power source to function . The most powerful system is the PV power conditioning unit.
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.
