Distributed model predictive control of all‐dc offshore wind farm for short‐term frequency support
IET Renewable Power Generation, Volume 17, Issue 2, Page 458-479, 3 February 2023., 2023 Abstract From technical and economical viewpoints, an all‐dc offshore wind farm (OWF) with a high‐voltage direct‐current (HVDC) connection, which is also known as HVDC‐connected all‐dc OWF, is the future trend for offshore wind energy applications. However, due to the decoupling effect of power converters, all‐dc OWF cannot directly provide short‐term ...

Robust Frequency Control of Microgrids: A Mixed H2/H∞ Virtual Inertia Emulation
International Transactions on Electrical Energy Systems, Volume 2023, Issue 1, 2023., 2023 This article proposes a robust inertial controller for converter‐based distributed generators employed in low‐inertia power systems like microgrids. The increasing penetration level of renewable energy sources based on power electronics converters in modern power systems reduces the inertial features of the system. It also increases concerns associated
