The 'profilograph': a toolbox for the analysis and segmentation of gas load curves

Conference WSOM 05 5-8 September 2005; International audience; The paper presents a method to allocate a class of a Kohonen map to a new customer without knowing anything about the variables used for the classification. In this study, a classification of daily gas load profiles is performed on a panel of Gaz de France customers. Then, we use a multinomial logit model to allocate a class to a new customer according to its additional variables. With this model, it is also possible to infer the probability to belong to each of the Kohonen classes. The main application for Gaz de France is the inference of the daily gas load for any customer.
