Cost‐effective secondary voltage control in dc shipboard integrated power system
IET Power Electronics, Volume 17, Issue 16, Page 2642-2655, 16 December 2024.In this paper, a cost‐effective secondary voltage control is proposed for the DC shipboard integrated power system. In this manner, the real‐time total cost minimization and state of charge balance are realized during the secondary voltage regulation process.

Prescribed‐time resilient current‐sensorless DC power converter control
IET Power Electronics, Volume 17, Issue 14, Page 2123-2133, 4 November 2024.Herein, a novel observer‐based sliding‐mode control approach is proposed to enhance cost‐effectiveness and reliability in the context of a DC‐DC buck converter supplying power to an unknown CPL. A state observer is designed to estimate the system's current based on voltage measurements and a non‐certainty equivalent adaptive update law is then ...

DC Shipboard Microgrid Modeling for Fuel Cell Integration Study
2019 IEEE Power & Energy Society General Meeting (PESGM), 2019 The integration of fuel cell technology in shipboard is essential for real fuel and pollution reduction in the marine sector. This integration can be pushed in the adoption of a dc shipboard power system (SPS). One of the impediments to this integration is the necessity to couple fuel cells (FCs) and battery energy storage systems (BESSs) and control ...
