The UK grid has encountered a series of events related to the Western HVDC link, resulting in disturbances to its converter stations and causing unexpected disconnections of transmission and distribution assets.
Given the significant impact of these events on the grid, the National Energy System Operator (NESO) has commissioned the National HVDC Centre to further investigate these incidents and any future similar occurrences, especially after the decommissioning of the converter station.
The National HVDC Centre will conduct these investigations using an offline EMT simulation tool with data provided by NESO.
