Power electronic traction transformers (PETTs) will be increasingly applied to locomotives in the future for their small volume and light weight. However, similar to conventional trains, PETTs behave as constant power loads and may cause low-frequenc

Bidirectional interlinking converter (BIC) is the core equipment in a hybrid AC/DC microgrid connected between AC and DC sub-grids. However, the variety of control modes and flexible bidirectional power flow complicate the influence of AC faults on B

In DC distributed power systems (DPSs), the complex impedance interactions possibly lead to DC bus voltage oscillation or collapse. In previous research, the stability analysis of DPSs is implemented based on mathematical analysis in control theory.

Since the fault dynamic of droop-controlled inverter is different from synchronous generators (SGs), protection devices may become invalid, and the fault overcurrent may damage power electronic devices and threaten the safety of the microgrid. Theref

Abstract The brushless doubly‐fed machine (BDFM) utilizes an asymmetric composite rotor featuring salient pole reluctance and magductance to effectively compensate for the phase shift in space, as well as enhance magnetic field modulation effects,

The transient responses of distributed energy resources (DERs) in a microgrid are dynamically correlated in spatial and temporal dimensions. Hence, the transient stability prediction in microgrids would require an effective modeling of time-varying c
