Résumé

In the field of energy analysis, time series forecasting techniques are widely used to predict customer electricity consumptions. To enhance the electricity forecasting accuracy, in current approaches, clustering techniques are first applied to identify groups of customers exhibiting the same electricity load profile, from which a representative consumption pattern can be extracted. This pattern is later used to predict customers’ subsequent electricity consumption. In the vast majority of clustering approaches, authors use the entire data set as input to identify customer consumption groups. However, using such a global methodology may affect load forecasting accuracy, as it does not consider the fact that customers’ consumption behavior may change at any time. Predicting customers' electricity consumption with such unstable behavior poses a serious problem for existing models. To overcome this constraint, we propose a hybrid approach capable of handling customers’ changeable electricity consumption. In summary, we propose a network-based approach which involves tracking cluster structures over time. From the evolving clusters, we develop a principled framework which simultaneously utilizes long-short term memory (LSTM) recurrent neural network and survival analysis techniques to forecast electricity consumption.
