Reliability Assessment for Flexible Interconnected Distribution Network Considering MMC Faults and Coordinated Multi‐Device Restoration

IET Generation, Transmission &Distribution, Volume 19, Issue 1, January/December 2025.
1. A refined component‐level reliability model for four‐port soft open points (SOPs) is developed, explicitly incorporating correlations among sub‐modules (SMs) of hybrid modular multi‐level converters (MMCs). 2. A load restoration optimisation model is formulated, explicitly integrating SOP fault modes to achieve optimal load recovery via multi‐device

Reliability of Power Modules in Corrosive Environments: Effect of Heating on Dendritic Corrosion Growth in the Isolation Trenches

IET Power Electronics, Volume 18, Issue 1, January/December 2025.
In this paper, applied heating was shown to effectively inhibit dendritic corrosion growth, formed in the power module isolation trenches in corrosive environments, by reducing the effective relative humidity and thereby the thickness of the adsorbed water layer on the ceramic substrate surface. The findings can be applied to enhance the reliability of
