Detection of anomalies and breaks in time series. Applications to the management of electricity production.

Summary Continental is the reference tool used by EDF for long-term electricity management. It is used to develop the operating strategy for the power plants distributed throughout Europe. the tool simulates several variables such as electricity demand, quantity generated and associated costs for each zone and each scenario. the objective of our thesis work is to provide methods for analyzing these production data in order to facilitate their study and synthesis. we collect a set of problems from continental users that we try to solve using anomaly detection techniques and breaks in the time series.
