Our Current Projects

ANALYSIS & SUPPORT: Core Industry Support

The National HVDC Centre works in partnership with the three onshore transmission owners and the system operator, who are all represented on the Centre’s Technical Advisory Board (TAB). We are funded such that we can work with these core clients on a variety of activities without any additional charges being applied. The HVDC Centre also has an obligation to support knowledge transfer and training to support GB industry in general with the acceleration and de-risking of HVDC technologies used to support the Net Zero transition. This is delivered by the Centre running training courses and knowledge dissemination activities like webinars.

ANALYSIS & SUPPORT: Analysis Support for HVDC Interconnector

The National HVDC Centre worked with Greenlink Interconnector Ltd (GIL) to support late-stage project delivery activities as they commissioned their new HVDC interconnection between the electricity grids in Ireland and Great Britain. The HVDC Centre performed studies using our specialist in-house analysis tools and provided an expert review of information to support activities between GIL and Siemens Energy, the converter supplier.

ANALYSIS & SUPPORT: NESO Western HVDC Link Performance Analysis

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, NESO has commissioned the National HVDC Centre to further investigate these incidents.

INNOVATION: BLADE

BLADE (Black Start Demonstration from Offshore Wind) is an innovation project. The overarching aim of the BLADE project is to bring black start and electricity system restoration from offshore wind to commercial reality by building the necessary cross-industry understanding. The aim is to do so by demonstrating the potential of state-of-the-art offshore wind turbines to provide black start services.

FUNDED BY: OFGEM’s Strategic Innovation Fund (SIF)

ANALYSIS & SUPPORT: SSEN-T System Performance Support

The HVDC Centre is working with SSEN Transmission’s System Performance team to undertake several inter-related activities in support of SSEN-T network development. The main goals of the work are to develop real-time AC system models of the GB network regions of interest to support the numerous upcoming HVDC projects connecting in the north of Scotland and to other parts of GB.

INNOVATION: Project Aquila Interoperability Package

Project Aquila is a world-leading project which will develop a Multi-Terminal, Multi-Vendor DC-hub in Peterhead; establishing the foundations for DC-Grids in GB. As part of the project, the National HVDC Centre is undertaking the workstream of “Aquila Interoperability”, which is a £ 2M project. The project team are working closely with the principle HVDC manufacturers to derive and demonstrate interoperable and vendor agnostic specifications for HVDC converters. They include the development of multi-terminal control, patenting and testing of principles allowing TSOs to specify multi-terminal control functions to deploy an HVDC network surrounding a switching station to interoperate across different vendors and with greater reliability and resilience than before.

INNOVATION: Horizon Europe HVDC-WISE project

The National HVDC Centre is one of 14 partners contributing to the Horizon Europe HVDC-WISE project. The goal of this project is to support further development of HVDC-based transmission grids by developing new reliability and resilience (R&R) oriented planning and analysis tools and identifying HVDC-based grid architectures and technologies that can be readily deployed to improve system performance and facilitate the integration of new renewable sources.

FUNDED BY: UK government’s Horizon Europe funding guarantee [grant number 10041877]

REPLICA HOSTING: Moyle Interconnector

The Moyle Interconnector, owned by Mutual Energy, links the electricity grids of Northern Ireland and Scotland through submarine cables running between converter stations at  Ballycronan More in Islandmagee, County Antrim and Auchencrosh in Ayrshire. The National HVDC Centre is hosting the replica control and protection cubicles on behalf of Mutual Energy; enabling us to support the upgrade and ongoing operation of the Moyle Interconnector.

ANALYSIS & SUPPORT: Support for the Shetland Extension of the Caithness-Moray HVDC Link

The National HVDC Centre is playing a pivotal role in the de-risking of what will both be the first multi-terminal VSC-HVDC connection in Europe, and an excellent insight into the design of future multi-terminal offshore connections and Multi-Purpose interconnection going forward.

REPLICA HOSTING: SCADA System Implementation

This project is to include GE PowerOn, as used in the Control Room, into the simulator setup at the National HVDC Centre. Adding this functionality would enhance the training that can be provided for the operators as it would give them the interface to the link that would be use in normal operation of the facility. This means that they would have the the equivalent to a full ‘flight simulator’.

ANALYSIS & SUPPORT: ESO offshore network operation, performance, and technical code impact

The increasing penetration of inverter-based resources and HVDC interconnections have created dynamic interactions, oscillations, and low inertia related stability issues. National Grid ESO’s HND project will introduce more and more DC links leading to a meshed AC-DC grid in near future.

The Electricity System Operator has requested that the National HVDC Centre model the offshore HND networks.
