Our Team

The Centre has assembled a team of HVDC experts who are internationally recognised as leaders in their fields. Together they provide HVDC experience across: academia, system operator, power systems consultancy, transmission innovation and HVDC suppliers.

Their specific areas of expertise are:

  • HVDC Coordination: Independent and holistic technical view across: system operator, network owners, interconnector developers and HVDC offshore wind developers;
  • Complex HVDC Systems: Design, simulation, and testing for complex HVDC systems;
  • HVDC AC Integration: Secure integration of HVDC & FACTs devices into complex/weak AC Networks
  • Offshore HVDC: Design and technical co-ordination of integrated offshore developments;
  • HVDC Control & Protection Interactions: Enhancing the robustness of control and protection approaches relating to multiple HVDC or FACTs devices;
  • HVDC Converter Modelling: Accurate modelling converter controls (incl: VSC/LCC, Real-time/Off-line);
  • Model Conversion and Validation: Appropriately converting models between packages, including model reduction and validation, and specific expertise in RSCAD; and
  • HVDC Research & Innovation: Leading a programme of research and innovation projects.

Benjamin Marshall

Ben is the HVDC Technology Manager, providing technical oversight at the Centre. Ben joins us from National Grid ESO where he focused on analysing the operation and design of the AC and DC transmission systems, dynamic stability performance and HVDC converter specification.

Simon Marshall

Simon manages the operation of the HVDC Centre, having developed the Centre from its original inception, through to a world-class centre of excellence. He oversees the work undertaken at the Centre, ensuring quality delivery and that confidentially is protected.

Simon previously managed the delivery of SSEN Transmission’s innovation portfolio.

Prior to joining SSEN Transmission, he was a senior consultant with Capgemini, delivering a range of transformation projects.

Colin Cameron

Colin was responsible for the delivery of IT infrastructure of The National HVDC Centre and is now the Centre ICT Engineer. Prior to working on The National HVDC Centre, Colin worked for SSE IT for 5 years where he had responsibility looking after SSE’s Renewables Centre of Excellence in Glasgow.

Colin enjoyed the technical challenge of designing the IT architecture of The National HVDC Centre ensuring that it can meet the current and future requirements of the Centre.

Ian Cowan

Ian has long had an interest in Transmission systems and is excited to be at the forefront of HVDC, one of the latest developments in that field.  As the Lead Simulation Engineer at the HVDC Centre, Ian not only undertakes simulation studies, but also coordinates the activities of the Simulation team at the Centre.

He is an experienced electrical engineer who has worked at the HVDC Centre from its opening in 2017, he brings technical consultancy experience combined with strong management skills to his role as Lead Simulation Engineer at the Centre. He has an MEng in Electronic and Electrical Engineering (with a focus on power systems) from the University of Strathclyde. He originally joined the National HVDC Centre as a Simulation Engineer from Mott MacDonald where he worked in the Power Systems Analysis team carrying out a variety of offline simulations on multiple platforms.

Since joining the HVDC Centre he has led the delivery of the following key projects: ‘[HVDC] Protection Systems Demonstration (WP9)’ as work package leader within the PROMOTioN project; Caithness-Moray Project Support; and Eastern Link Project Support.

Dong Chen

Dong Chen joined HVDC Centre as a simulation engineer. He is responsible to develop models of power electronics enabled power network. This include functional design of offshore power grid. He previously was a lecturer in electrical power engineering with Glasgow Caledonian University. His research interests include control, stability, and protections of power electronics enabled power system. He has a PhD degree in electrical power engineering and is a senior member of IEEE Power and Energy Society. He serves as an active member of a few relevant BSI and IEC working groups and associate editor for both IET Power Electronics and IEEE Transactions on Power Delivery.


Linda Rowan

Linda is the Centre’s Technical Project Officer, responsible for coordinating the delivery of projects at the Centre. She previously worked at TÜV SÜD as a Project Manager for the past 20 years. Over this period, she has managed a diverse range of projects ranging from performance testing of wind turbines to construction of multimillion-pound test rigs. She was directly involved with many aspects of the UK National Measurement System (NMS) including formulation and delivery of programmes and projects in support of the NMS.  She also supported many aspects of TÜV SÜD’s knowledge transfer activities, for example through publications, presentations and webinars.

Nikhil Sharma

Nikhil has recently joined the HVDC Centre as a Simulation Engineer. With 8 years experience in Transmission & Distribution Sector, he has a Bachelor of Technology (B. Tech) in Power Engineering (Electrical Specialisation). Previously at Tata Power-DDL (ESO), Nikhil was responsible for carrying out Protection & Testing of AIS/GIS Grids; and while at Siemens he carried out HVDC Projects’ Functional and Dynamic Tests with Simulation models.



Fabian Moore

Fabian has recently joined the HVDC Centre as a Simulation Engineer. He joins us from National Grid Electricity Transmission, the owner of the high-voltage transmission network in England and Wales. There he focused on managing power quality issues arising from power electronics being connected to the AC system, and the simulation of electromagnetic transients in AC systems. He has previous experience working for the Distribution Network Operator in London in both operational and planning roles. He has an MEng degree in Electrical and Electronic Engineering.


Shangen Tian

Shangen joined the HVDC centre as a simulation engineer in March 2022. He is responsible for undertaking detail HVDC simulation studies in offline and real-time using vendor-supplied hardware and models. He received a B.Eng. degree in Electronic & Electrical Engineering from University of Strathclyde, Glasgow, United Kingdom, and has been a PhD researcher with the department of Electronic & Electrical Engineering at the University of Strathclyde, Glasgow, United Kingdom. His research area is mainly focused on design of converters for offshore HVDC applications, grid forming converter and control of power electronics.
