Abstract :
In this paper we present a methodology based on a combination of clustering and forecasting techniques. The proposed method is built in two phases: In the first phase, a clustering algorithm is used to identify buses clusters with similar daily load profile. In the second phase we introduce an aggregate structure for to foresee each bus. The methodology was applied on bus load data from the Brazilian North/Northeast system and the results showed that the model was efficient with 2% to 4% average percentage error level on the buses. The obtained forecasting was compatible with the load safe operating levels of the Brazilian power system.
