TL;DR: A general method for fault detection and isolation (FDI) is proposed and applied to inverter faults in drives of electric vehicles (EVs) based on a change detection algorithm, which allows multiple fault indices (FIs) to be combined to retrieve the most likely state of the drive.
Abstract: A general method for fault detection and isolation (FDI) is proposed and applied to inverter faults in drives of electric vehicles (EVs). This method is based on a change detection algorithm, which allows multiple fault indices (FIs) to be combined to retrieve the most likely state of the drive. The drive topology under study is a six-leg inverter associated with a three-phase open-end winding machine. Due to the inherent fault-tolerant topology, the conventional FIs are no longer effective. Therefore, an analysis of simulations under faulty conditions leads to the derivation of suitable FIs. These are based on the envelope of the phase currents, as well as their instantaneous frequency. Specific operating conditions related to the EV environment are taken into account, such as the flux-weakening region and energy recovery. In these modes of operation, FDI can be affected by uncontrolled currents circulating through the free-wheeling diodes. Finally, the performances of the FDI scheme are evaluated under steady-state and nonstationary conditions through simulations and experimental results.

TL;DR: This work considers the shape-topology optimization of the Navier-Stokes problem and proposes a new algorithm based on the variational level set method, which can be maintained without re-initialization and drastic topology change can be handled easily.

TL;DR: In this letter, a novel consensus-based approach is proposed to solve the energy management problem for islanded microgrids by taking the incremental cost of each agent as the consensus variable and through limited communication between neighboring agents can quickly converge to optimal solutions.
