A Novel Approach to Account for Uncertainty and Correlations in Probabilistic Power Flow

Il paper propone una metodologia per valutare la probabilità di superamento dei limiti operativi in situazioni di normale esercizio e sotto contingenza, considerando le iniezioni di potenza incerte e correlate.

Power system security assessment techniques can greatly benefit from the adoption of probabilistic approaches, as these can thoroughly describe the effect of uncertainties on the operating condition. The paper proposes a methodology to evaluate the probability of exceeding operational constraints under normal and contingency situations, accounting for uncertain, correlated power injections.

In the proposed methodology, an analytical technique for probabilistic power flow is combined with copulas, the latter being introduced to deal with correlations. Copulas allow representing in an effective way the correlation information among variables, i.e. the multivariate distributions of stochastic variables. A test system based on a realistic transmission network is used to exemplify the method.
