This paper proposes a new methodology that quantifies the reserve needed on a system considering the uncertain nature of the wind power. The reliability of the system is used as an objective measure to determine the effect of increasing wind power penetration. The methodology is applied to a model of the all-Ireland electricity system, and results show that as wind power capacity increases, the system must increase the amount of reserve carried or face a measurable decrease in reliability.
