The control system incorporates a maximum power point tracker (MPPT) that continuously determines the optimal power for the operational PV array. The control strategy encompasses regulating both active and reactive power, accomplished by manipulating the load angle and the magnitude of the inverter’s output voltage.
The control strategy encompasses regulating both active and reactive power, accomplished by manipulating the load angle and the magnitude of the inverter’s output voltage. By adjusting the reactive power injected into the grid, the controller ensures that maximum active power is fed into the grid at a unity power factor.
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 .
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 .
