Abstract
The present research develops a comparative study of three different methodologies, which are applied for fault detection and identification (FDI). The studied faults are sensing in AC/DC Hybrid Microgrids (HMG). The study addresses the use of methods based on: Kalman Filter, Artificial Neural Networks and Fuzzy Logic, all applied to local HMG controllers. To compare and validate the performance of the proposed methods, three failure conditions were proposed: operation without fault, abrupt failure or loss of sensing and incipient additive failure. As a conclusion, the Kalman Filter is faster in its execution and decisionmaking, however the method based on Fuzzy Logic presented a lower average for the residual error. All simulations were developed in Matlab/Simulink. Finally, an algorithm based on the minimum error was proposed to allow the automatic selection of one of the studied FDI strategies.
