In view of the current discussion on increasing energy efficiency and reducing CO2 emissions, it can be expected that reactive power and harmonics will come into greater focus also with regard to politics. Reactive power drawn from the grid and network disturbances in the form of harmonics cause additional losses in the transmission and distribution network, which must be covered through the use of primary energy in power plants. Fair, source related distribution of the costs will certainly be more of a topic in the future.
A changing power grid calls for new reactive power compensation solutions to improve power quality. This publication gives a review about the different technologies.
