Tim Green

This PhD project at Imperial College London, funded by GE Vernova, focuses on the protection and technology of multi-terminal Medium Voltage Direct Current (MVDC) distribution systems. The research aims to analyse short-circuits and fault scenarios in medium-power distribution networks that utilize DC links for integrating renewable energy resources such as photovoltaic (PV) farms and electric vehicle (EV) rapid-charging infrastructure. The successful candidate will develop and evaluate advanced fault detection and location algorithms, contributing to the technological advancement of MVDC systems. Supervised by Dr Adria Junyent-Ferre and Professor Tim Green, the project offers a unique opportunity to collaborate closely with the MVDC Technology team at GE Vernova. The candidate will split their time between Imperial College London and GE Vernova's offices in France, with the schedule determined at the project's outset. The research outputs will directly support solution development at GE Vernova and will be disseminated through peer-reviewed journals and conferences. Key research activities include assessing the state of the art in MVDC protection, developing mathematical and simulation models for fault studies, reviewing power electronic converter topologies, conducting fault transient studies, and extending protection mechanisms for complex, interconnected systems. The project is embedded within a leading power engineering research group, offering strong industrial relevance and opportunities for secondments in France. The studentship covers home/overseas tuition fees, a tax-free stipend for 3.5 years at the UKRI London rate (approx. £22,780 per year for 2025/26), and support for research expenses and travel. Applicants should have a first-class Master’s degree (or equivalent) in Electrical Engineering or a related field, with expertise in power electronics, circuits, and protection engineering. Experience with modelling and simulation of power systems or power electronic converters is required, and familiarity with MVDC or HVDC systems is desirable. Strong communication skills and willingness to travel are essential. The studentship is expected to start on either 1st July 2026 or 26th September 2026, with an earlier start date preferred if possible. To apply, submit an Expression of Interest via the provided online form. Shortlisted candidates will be invited to an online interview, and the final candidate will complete the application through Imperial College London's postgraduate admissions.

Imperial College London invites applications for a fully funded PhD studentship in the Control and Power Group, Department of Electrical and Electronic Engineering. This position offers an exciting opportunity to work at the intersection of network science and artificial intelligence, focusing on the analysis and optimization of modern power systems in the era of renewable energy. The project is supervised by Dr. Homayoun Hamedmoghadam (ICRF Fellow) and Professor Tim Green (Professor of Electrical Power Engineering), both at Imperial College London. The research aims to address the challenges posed by the transition to renewable energy sources such as wind, solar, and batteries, which are integrated into power grids via electronic inverters. This shift fundamentally changes the operation and stability of power networks, requiring new theoretical and practical approaches. The central vision of the project is to combine the strengths of Network Science and Artificial Intelligence to develop innovative methodologies for the design, expansion, and control of power systems. The student will identify minimal yet high-impact interventions—such as structural modifications, control placements, and operational adjustments—to optimize grid architecture and ensure reliable operation in a net-zero future. The research will focus on maximizing the security and resilience of power networks while minimizing infrastructure costs, delivering significant societal and economic benefits. Key objectives include: Conducting a comprehensive literature review on network science analytics of power system stability, net-zero transition impacts, and structural interventions for controlling network dynamics. Analyzing the dynamical effects of renewables integration, including desynchronization phenomena, instability mechanisms, and cascading failure events. Developing theoretical frameworks and practical tools for network upgrade and restructuring to reinforce resilience. Designing AI pipelines that ground the learning of power system dynamics in physical reality and network science interpretation. The successful candidate will be based at Imperial College London, working within a world-leading research environment. The studentship is funded by the Department of Electrical and Electronic Engineering and covers home-level tuition fees, a tax-free stipend at the UKRI London rate (£22,780 per year for 2025/26) for 3.5 years, and support for research expenses and travel to collaborators and conferences. Overseas applicants are welcome but must cover the difference between Home and Overseas tuition fee rates. Eligibility: Applicants should hold a first-class Master’s degree (or equivalent) in Computer Science, Electrical/Electronic Engineering, Mathematics, Physics, or related fields. Suitable backgrounds include machine learning, network science, control engineering, and power engineering. Candidates must be highly motivated and meet Imperial College London’s postgraduate eligibility requirements. Application Process: Apply online via the provided link, including a cover letter and CV.
