Frequency containment reserves dimensioning and target performance in the European power system

This paper presents the methodology and results of a risk assessment to match the frequency containment dimensioning and resulting security performance by analyzing the relationship between the available amount of frequency-response reserves and the frequency quality performance in the European power system. The proposed dimensioning technique is simulated applying Monte Carlo simulations to measurements from the European power system. The results show that as the risk of running out of frequency containment reserves due to market induced load-generation imbalances increases, the amount of containment reserves must regularly be validated and eventually adjusted or the system will face a measurable decrease in reliability.
