#### Abstract

This paper investigates the impact of reconfiguration on the efficiency of distribution networks operation. With this purpose, an advanced method of analysis and optimization of Medium Voltage grids configuration has been developed. The proposed model is based on a procedure that optimizes the network structure during a given time interval (e.g. a day or an entire year); both the cases of static (not changing over the whole time interval in analysis) and dynamic configuration have been considered.

The algorithm is divided into two distinct phases: first, the expected profiles of load and generation are managed, solving a classical load flow problem for each time sample and structuring results in appropriate matrices. In the second phase, the previously calculated matrices are processed, defining the best solution w.r.t. a predefined metric.

A model of a real Medium Voltage grid has been processed; the results obtained confirm that the reconfiguration may entail economic improvements w.r.t. real losses on the feeders. In particular, even a reduced number of reconfiguration actions during the year allow a significant decrease in losses, consequently the proposed approach results to fit very well with the Distribution System Operator needs. The innovative contents of the paper are in the procedure developed w.r.t. the DSOs perspective and in the analysis performed on a real life MV distribution grid. In particular, the authors believe the latter is essential to evaluate correctly the performances of the proposed procedure *Copyright © 2014 Praise Worthy Prize - All rights reserved.*
