Combined modelling of long, short interruptions and voltage dips: A Markovian solution

A model of an electrical system node is presented. It allows predicting the effects of long and short interruptions as well as of voltage dips on final users starting from statistical input data. The model is developed using an extension of the homogeneous multi-state Markov process to take into account the non exponential nature of the failure-repair process. Case studies demonstrate the usefulness of the model for practical applications.
