Faults Detection and Isolation for Energy Management System Based on Hybrid Observer

摘要

The following paper deals with the problem of diagnosis and isolation of faults in energy management system. To achieve that, a hybrid modeling of the system is proposed. It also presents a review of the analytical approach of residual generation using a hybrid observer with unknown inputs; a bank of residual generators is exploited in order to detect and isolate faults in case of disturbance. In order to show that our method is effective, simulations using Matlab/Simulink are implemented.
