The impact of wind power forecast uncertainty has been amplified by the deepening penetration. To guarantee system security and reliability, sufficient dispatchable generation transmission capacities have to be reserved. Currently, research carried out improve operational performance optimizing schedules considering uncertainty. However, most methods are designed cover a given risk level uncertainty, which is determined ex ante. With increase in capacity, defining priori without unit...
