Constructing the Bayesian Network for components reliability importance ranking in composite power systems

► A simple approach is presented to construct the Bayesian Network (BN) of a power system. ► The approach is based on the capability of the BN to learn from data. ► The approach can be applied to large power systems. ► Different probabilistic assessments are easily provided by the constructed BN. ► The importance of each component on system reliability can be easily evaluated.
