Active Power, Reactive Power, Apparent Power, and the Role of Power

Transformers and induction motors use reactive power to produce a magnetic field. Transformers also need reactive power to generate a magnetic field in the primary coil and induce a voltage in the secondary coil. Therefore, if the reactive power supply is not adequate, the transformer will not transform voltages and the motor will not rotate.

Active/reactive power control of photovoltaic grid‐tied inverters

The amount of injected reactive power is calculated based on the injected active power and a nominal current of the inverter. The injection of the active power gives priority over the reactive power in, although based on the grid codes and standards, during voltage sags, the priority must be assigned to the reactive power.
