reliability analysis of distribution systems has
been attracting increasing attention. A special concern pertains
to the distribution networks on which most failures occurs. The
optimization of distribution system of breakers and power
switches is a possible strategy to improve reliability. The paper
describes development procedure for modelling restoring after a
fault and calculating associated reliability indices and customers’
outage costs. The developed model of the network and reliability
and outage costs calculating algorithm is suitable for multicriteria
analysis of the network. Proposed reliability and outage
costs calculation algorithm is based on Monte Carlo simulation
and genetic algorithm.
