Future Perspective and Conclusions C Glossary S E Bibliography L Biographical Sketches E P Summary N M U In the event of unexpected failure of electrical power supply units or power transmission A equipment consumers and utility grids have spare electrical power that is always ready and can act within seconds or keep the supply to the consumers uninterrupted. These are called S spinning reserves and range from a few Watts to tens of megawatts. One needs spinning reserve also at utility power systems to control the frequency of the produced electricity.
