Valuation of Distribution System Lines to Improve the Restoration Process and Enhance the Resilience Index with Considering DGs

In order to increase the resilience of distribution system against natural disaster and human attacks, before the events, the value of the monitored system assets should be identified according to different factors so that during the crisis, restoring of lost loads be done faster and qualitatively better. This paper is based on price-based modeling in which load value, to consider the importance of demand side; failure rate, line availability; intrinsic value of lines, to consider investment cost, as well as topology factor, to emphasize The configuration of grid was taken into consideration. In order to observe the impact of DG on the grid lines evaluation, it was investigated in two states: with and without DGs. The results, in addition to demonstrating the network sensitivity to the influential factors, show that distributed generation has a potential to change ranking of valuation and to help improve the process of restoring the distribution system.
