A Series‐Connected Low‐Voltage Energy Storage MMC‐HVDC System for Offshore Wind Power Transmission

open access: yesIET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This paper proposes a series‐connected low‐voltage energy storage MMC for offshore wind power transmission. The energy storage submodule valve group is vertically installed in a grounded container near the electrode line, while the high‐voltage cell‐hybrid submodule valve group remains mounted on the base‐supported valve tower.
