Intelligent system for multivariables reconfiguration of distribution networks

This paper proposes a new distribution network reconfiguration approach in normal operating conditions. The multivariables are considered such as the energy losses minimization of the primary network and two reliability indices. The selection strategy of network configuration is based on a heuristic method. The method considers only the automated equipment such as switches and remote controlled reclosers in the new configuration analysis. The AHP (Analytic Hierarchic Process) method is used to define the weights for the optimization criteria and to determine the best switching sequence of the network reconfiguration. The reconfiguration is performed by monitoring the real time network. Changes in demand feeders are considered and analyzed by load rates. Also, the best setting for each operation level is defined. The results of the implemented techniques indicate a satisfactory methodology. Tests were performed using a real power utility system.
