This paper describes a technique for evaluating reliability of a composite distribution system having Distribution Generator (DG) sets. The capacity of a composite distribution system includes capacity of a distribution substation and distribution generator sets. The capacity of a distribution substation has been assumed to be a continuous random variable whereas Markov modeling has been adopted for checking availability of DG sets. Extreme minimum and maximum distributions have been used for capacity and load on the distribution system. Therefore, it is worst case reliability evaluation of the composite distribution system. Probability of failure of the composite distribution supply system has been evaluated using Monte Carlo simulation. A case study has been considered for explaining the developed algorithm.

    The K-out-of-N configuration is a typical form of redundancy techniques to improve system reliability, where at least K-out-of-N components must work for successful operation of system. When the components are degraded, more components are needed to meet the system requirement, which means that...

    We introduce an estimate of the entropy $\mathbb{E}_{p^t}(\log p^t)$ of the marginal density p t of a (eventually inhomogeneous) Markov chain at time t=1. This estimate is based on a double Monte Carlo integration over simulated i.i.d. copies of the Markov chain, whose transition density...

    A () random variable is said to be of phase type if it can be represented as the time until absorption in a finite state absorbing Markov chain. Univariate phase type random variables are useful because they arise from processes that are often encountered in applications, they have densities...
