Stability‐Driven Adaptive Virtual Impedance for DC Microgrids With Multiple Pulsed Loads

IET Smart Grid, Volume 9, Issue 1, January/December 2026.
Multiple pulsed loads cause rapid operating‐point migration and load‐impedance contraction in islanded DC microgrids, degrading source–load stability and limiting fixed virtual‐impedance designs. This paper develops a stability‐margin‐driven adaptive virtual impedance method that coordinates virtual resistance, virtual inductance and dynamic ...

Coordinated Control of a Hybrid-Electric-Ferry Shipboard Microgrid

IEEE Transactions on Transportation Electrification, 2019
DC and dc/ac hybrid distribution and energy storage for shipboard power systems (SPSs) are becoming a major trend due to efficiency improvement, space saving, and maneuverability enhancement. This paper has taken a real hybrid-electric-ferry as a case-study to integrate battery units (BUs) to a dc bus for supplying the propulsion motors.
