Reactive power burdens the electricity grid without contributing to the transport of energy. In contrast to active power,
which is transformed by loads into warmth, motion or light, reactive power provides no visible benefit.
Furthermore, the overall grid infrastructure must be designed for the resulting apparent power, which is the geometric sum
of active and reactive power. This way, large energy transport losses result from reactive power in the distribution grid.
On the other hand, if the unavoidable phase shift in the distribution grid is compensated, the transport losses are reduced.
The cable resources being freed up can then be used for the transfer of additional active power. In particular, the
decentralised feed-in of reactive power thus contributes to more efficient operation of the electricity grid.
