METHOD FOR PROVIDING CONTROL POWER TO STABILIZE AN ALTERNATING CURRENT NETWORK

摘要

The invention relates to a method for providing control power for stabilizing an alternating current network which operates at a specified frequency. Said method uses an energy accumulator which can absorb and emit the electric energy and which comprises at least two electrochemical elements which differ in terms of the degree of efficiency. Said electrochemical element with the lower rate of efficiency changes less often than the electrochemical element with the higher rate of efficiency, from one state, in which the electrochemical element with the lower rate of efficiency absorbs energy, into another state in which said electrochemical element with the lower rate of efficiency emits energy.
