Probabilistic assessment of constraint volumes on active networks

Active Network Management (ANM) presents an effective approach to facilitating the connection of renewable generation onto increasingly congested networks. Estimating the severity of constraint experienced by managed generators is a key requirement in order to successfully evaluate the impact of implementing ANM solutions. This paper describes an established method of constraint analysis, its requirements, and outcomes. This approach to constraint analysis is developed further, introducing a probabilistic method for the estimation of curtailment volumes. Examples are provided illustrating the outcomes from such studies.
