Lyapunov‐Based Novel Integral Backstepping and Integral Sliding Mode Controllers Design for Efficient Voltage Regulation of Resilient DC Microgrid

International Journal of Energy Research, Volume 2025, Issue 1, 2025.
Microgrids (MGs) offer a more efficient and reliable energy provision than conventional grids due to their ability to function autonomously from the primary grid. This work investigates a stand‐alone direct current MG (DCMG) with multipower sources of photovoltaic (PV), wind, and storage devices such as batteries, ultracapacitors (UCs), and hydrogen ...

A Novel TKEO With the Decision Tree–Based Method for Fault Analysis of the HVDC Transmission Link Fed by Offshore Wind and Solar Farms

International Transactions on Electrical Energy Systems, Volume 2025, Issue 1, 2025.
Detecting and classifying various faults on high voltage DC transmission (HVDC) lines and pinpointing their locations are crucial tasks for the power system’s efficient operation. This paper presents a Teager–Kaiser energy operator (TKEO) technique with a decision tree–based fault type classifier to monitor power system faults on the HVDC transmission ...

Recent Advances in Design of Fault Current Limiters for Modern Power Grid Networks: A Critical Review

Journal of Electrical and Computer Engineering, Volume 2025, Issue 1, 2025.
Fault current limiters (FCLs) are essential components in modern power systems for critical protection against the damaging effects of fault currents. With extensive short circuits, routine electrical faults, and an increasing risk of failure due to unprecedented events, the development of different types of FCL has gained attention.

A new series‐parallel active compensator for DC microgrids based on three‐leg voltage source converter

IET Power Electronics, Volume 17, Issue 16, Page 3071-3082, 16 December 2024.
This article proposes two new topologies of DC series‐parallel active compensators for voltage and current compensation in DC microgrids. In the first topology, the back‐to‐back connection of an isolated bidirectional DC/DC converter with a full‐bridge converter is used to compensate voltage and current. In the second one, to eliminate the transformer,
