A practical approach for estimating future outage costs in power distribution networks

Quantitative reliability analysis is integrated as a part of a distribution network information and design system. The outage rates, outage durations and costs of outages are evaluated using the data included in the network database together with the reliability data for network components and the per unit values for the energy not supplied. Using the reliability calculation program together with other programs, optimum development plans for each network can be studied. In these studies, both the technical restrictions and the total costs, including the costs of investments, losses, and outages, must be included
