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. .
As an interface device between photovoltaic cells and the power grid, the photovoltaic inverter converts the power of the photovoltaic cells into AC power and transmits it to the power grid. It plays a vital role in the photovoltaic grid-connected power generation system.
Photovoltaic inverters can only generate electricity during the day, and the power generated is affected by the weather and has unpredictability and other issues. The energy storage converter can perfectly resolve these difficulties. When the load is low, the output electric energy is stored in the battery.
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.
Therefore, inverters will be equipped to detect and mitigate faults, ensuring system reliability and minimizing downtime. Moreover, robust control strategies will enable PV systems to operate autonomously during grid disturbances, providing essential services such as islanding and grid support functions.
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 .
