Abstract:
The increase of renewable energy resources leads to the substitution of large-scale power plants. Coalitions of distributed units such as consumers, producers and storage devices must provide ancillary services for frequency and voltage control. This implies two main challenges: the volatile character of those units must be taken into account for both, the dimensioning of frequency control reserves and the provision of those reserves. In this paper, a new method for dynamic dimensioning of frequency control reserve is discussed and a model for estimating the resulting error is given. Furthermore, a concept for dynamic provision of frequency control by distributed coalitions is introduced and a model for assessing the remaining risk is proposed.
