What is reactive power?

Reactive power is the power that flows back from a destination toward the grid in an alternating current scenario in electrical grid systems. The unit of reactive power is kilo volt-ampere reactive (kVAR) or MVAR. The voltage and load are static, and to put it simply, the direction of energy is "one way," but in alternating current, there are different phases having to do with elements of the system like capacitors and inductors in a direct current system.
