Application assessments of distribution network minimum loss reconfiguration

Application aspects of optimal distribution network reconfiguration are highlighted in this paper. The problem is raised frotn the theoretical solution level to the practical implementation assessment level. For that purpose, a complex methodology for operational and short-term planning analyses of distribution systems is created. It manly regards non-automated or low level automated distribution systems. Optimization of a distribution network configuration for a given loading condition is done by the heuristic method presented in [I]. But, the methodology appropriateness to the practical applications is attained by introducing an original method for load estimation in distribution systems with minimum infonnation [2]. Furthermore, the optimization results are evaluated throughout an appropriate costhenefit analysis. This way composed tool becomes flexible, allowing appraisal of the network reconfiguration potential benefits, as well as the economically approved frequency of switching. The results of the study on Skopjeʹs distribution network are presented.
