Abstract
A method for providing a requested real power including receiving the requested real power at a transmission feed-in point; using a real power band with an upper band limit and a lower band limit, each of which is disposed with an offset from the requested real power. The real power band furthermore comprises at least one control threshold value between the upper band limit and the lower band limit. The method includes controlling at least one regenerative energy generator depending on the at least one control threshold value, in particular in order to provide the requested real power as transmission power at the transmission feed-in point.
