Reactive power control
In the grid—connected operation mode, the PCS can control grid-connected reactive power
by means of power factor and reactive power ratio control. In the VSG grid—connected op-
eration mode, the grid-connected reactive power can be controlled by means of reactive
power instruction regulation and voltage instruction regulation.
