Systems and methods for providing controlling power capacity during the operation of a regenerative power generating unit

Abstract

A method for delivering controlling capacity to a regenerative power generating unit driven by a strongly fluctuating primary energy source includes routine determination of the actual uncertainty with which compliance with the target value for the controlling capacity ΔPis achieved, in consideration of the fluctuating primary energy source, routine calculation of a dynamic security margin based upon the actual uncertainty, routine adjustment of the target value (P) on the basis of the requisite controlling capacity and the dynamic security margin. Statistical uncertainty is determined and the target value is then dynamically offset such that a corresponding buffer margin (security margin) is generated: large in the event of high uncertainty, low in the event of low uncertainty. Under consistent wind conditions, the security margin is significantly narrower, thus resulting in a larger target value.
