Ranking the Radial Configurations for Minimum Losses Distribution System Reconfiguration. Part 2: Intra-day Time-domain Assessment

This paper applies the approach indicated in the companion paper (Part 1) to study the persistence of the optimal configurations in distribution systems with time- dependent generation and load patterns. The solution ranking is carried out at each time step, then a comparison among the solutions is made in the perspective of dividing the time period during the day to apply intra-day reconfiguration separately for the daylight and the night periods. The related savings in the energy losses with respect to maintaining the same globally optimal configuration during the day are illustrated and discussed on a test network example. Three performance indices are defined to obtain and compare the corresponding ranking of the configurations during the time period considered.
