Resilient Control of Offshore Wind Transmission Systems for a Net-Zero Grid

About the Project

This PhD scholarship is offered by the EPSRC CDT in Offshore Wind Energy Sustainability and Resilience; a partnership between the Universities of Durham, Hull, Loughborough and Sheffield. The successful applicant will undertake six-month of training with the rest of the CDT cohort at the University of Hull before continuing their PhD research at Durham University.

Offshore wind is poised to supply a large share of the UK’s electricity, but the transmission links that carry this power ashore remain a vulnerability. As the system becomes dominated by power-electronic converters and multi-terminal HVDC grids, faults can trigger unstable behaviour and slow recovery. Every extra minute of curtailed export increases costs and erodes confidence in scaling offshore wind. The challenge is clear: we need offshore transmission that not only rides through severe events, but also recovers quickly, cleanly and safely.

This project tackles that challenge by developing grid-forming HVDC control strategies that stabilise voltage and frequency during contingencies and enable fast, oscillation-free restoration after faults. The work aims to cut downtime, reduce energy not served and provide practical support for black-start and re-energisation procedures. The impact is a step-change in offshore system resilience, directly supporting secure integration of large volumes of offshore wind on the path to net zero.

The approach blends rigorous control design with high-fidelity electromagnetic transient (EMT) modelling. You will build coupled AC-MTDC models of offshore networks and onshore grids, design grid-forming controllers (e.g. virtual synchronous machine), and stress-test them across realistic extreme-event libraries. Where feasible, you will validate with hardware-in-the-loop facilities and co-develop scenarios with industrial partners, translating results into open models and software for operator use.

The outcomes will support more secure offshore power delivery, reduced disruption during extreme conditions, and greater confidence in scaling offshore wind as a cornerstone of the UK’s net-zero grid.

This project is well suited to candidates with backgrounds in electrical engineering, power systems, control or power electronics who enjoy modelling, algorithms and practical validation. You will gain sought-after expertise at the intersection of EMT simulation, converter control and system resilience, which are skills in high demand across transmission owners, HVDC vendors, offshore developers and test centres, as well as a strong platform for an academic career.

Training & Skills

You will benefit from a taught programme, giving you a broad understanding of the breadth and depth of current and emerging offshore wind sector needs. This begins with an intensive six-month programme at the University of Hull for the new student intake, drawing on the expertise and facilities of all four academic partners. It is supplemented by Continuing Professional Development (CPD), which is embedded throughout your 4-year research scholarship.

There are a number of training opportunities available through Durham University, including Advanced Research Computing (Git/Python/ML/ HPC) and Smart Grid Lab training for EMT/HIL practice. You will also be able to access courses through the National HVDC Centre, PhD short courses (e.g. Aalborg: grid-forming), and EMT training.

Entry Requirements

If you have received a First-class Honours degree, or a 2:1 Honours degree and a Masters, or a Distinction at Masters level with any undergraduate degree (or the international equivalents) in Computer Science, Engineering, Physics or Mathematics and Statistics, we would like to hear from you.

If your first language is not English, or you require Tier 4 student visa to study, you will be required to provide evidence of your English language proficiency level that meets the requirements of the Aura CDT’s academic partners. This course requires academic IELTS 7.0 overall, with no less than 6.0 in each skill.

Guaranteed interview scheme

The CDT is committed to generating a diverse and inclusive training programme and is looking to attract applicants from all backgrounds. We offer a Guaranteed Interview Scheme for home fee status candidates who identify as Black or Black mixed or Asian or Asian mixed if they meet the programme entry requirements. This positive action is to support recruitment of these under-represented ethnic groups to our programme and is an opt in process. Find out more.

How to apply

Applications to the EPSRC CDT in Offshore Wind Energy Sustainability and Resilience are made to the University where the PhD project is based. You will find full instructions and links on the CDT website.

Applications for September 2026 entry will be considered on a rolling basis and applicants are therefore strongly encouraged to apply as early as possible.

Shortlisted candidates may be invited to interview as applications are received.

As offers may be made before all applications are reviewed, early application is strongly encouraged.

Funding Notes

The Offshore Wind CDT is funded by EPSRC, allowing us to provide scholarships for Home students that cover fees plus a stipend set at the UKRI nationally agreed rates, circa £20,7980 per annum at 2025/26 rates (subject to progress).
