RESUMO

This work consists in proposing a methodology based on Fuzzy Logic to obtain an index, which classifies the buses more suitable to install a distributed generator in an electric power distribution system. Themethodologywas developed taking into consideration the difficulty tomaintain a suitable voltage profile in distribution systems, so the methodology results in large, index values for the buses in which the installation of generators results in a more suitable voltage profile. Another aspect included in the methodology is the minimization of the real power losses. Applying a set of fuzzy rules, the index is calculated by setting membership values to the bus voltage and load real power . The advantages of this methodology are that the classification of the variables into fuzzy sets, which allow the linguistic translation of the system operator knowledge and so his experience of operating the system can be employed in the process of allocating distributed generators in the system and when compared to traditional techniques of analysis, does not need of consecutive runs of power flows, it is necessary only to obtain the state operating of the network through only one power flow in base case
