PhD scholarship in 'Control and stability of meshed offshore grids with diode rectifiers and VSC HVDC'

jobbeskrivelse:
The Department of Wind Energy in the Technical University of Denmark (DTU Wind Energy) is seeking a PhD for the Wind Energy Systems Section (VES). You will be part of the international team carrying out research in wind power integration and planning, where the working language is English. Our research is function oriented in the sense that we direct the research towards issues that are relevant for industrial development and applications, and we work in projects with system integration, control concepts for wind turbines, wind power plants, electrical components, grid connection and large-scale wind energy penetration. Please look at http://www.vindenergi.dtu.dk for more details on the type of activities we undertake. Responsibilities and tasks In order to unlock the full potential of Europe’s offshore resources, network infrastructure is urgently required, linking offshore wind parks and on-shore grids in different countries. HVDC technology is envisaged but the deployment of meshed HVDC offshore grids is currently hindered by the high cost of converter technology. A potentially key technology in this direction is presented by the Diode Rectifier (DR) offshore converter. This concept is ground breaking as it challenges the need for complex, bulky and expensive converters, reducing significantly investment and maintenance cost and increasing availability. The PhD study will investigate the minimum requirements on onshore and meshed HVDC offshore power systems (including both VSC and DR) in order to adapt and extend existing grid codes. The interoperability and control of converters and diode rectifiers during normal operation and faults and the effects of the investigated offshore topologies on the onshore AC grid (e.g. frequency stability) are investigated. The PhD study will, among others, bring contributions to the research related to: •Defining model parameters, control objectives and operational assumptions for the meshed HVDC offshore topologies •Development of simulation models for the meshed offshore HVDC topologies •Investigation and functionality demonstration of the meshed offshore HVDC topology system interoperability by simulation •Contribution to recommendations for minimum grid connection requirements to onshore power system The PhD study will be part of the large Horizon 2020 - Project “PROgress on Meshed HVDC Offshore Transmission Networks” – PROMOTioN. Qualifications The successful candidate is required to have: •MSc degree (or equivalent) in Power System or Electrical Engineering •Documented background in power system stability, HVDC, modelling and converter control •Documented background in power system simulation tool DIgSILENT PowerFactory •Proficiency with time-stepping simulation of engineering systems, e.g. Matlab •Understanding the link between simulation environment and field implementation •Ability to work in a project team and take responsibility for own research goals •Ability to communicate, read and write in English Prior knowledge on wind power – in addition to the above requirements – will strengthen the candidate profile. Approval and Enrolment The scholarships for the PhD degree are subject to academic approval, and the candidates will be enrolled in one of the general degree programmes of DTU. For information about the general requirements for enrolment and the general planning of the scholarship studies, please see the DTU PhD Guide. We offer We offer an interesting and challenging job in an international environment focusing on education, research, public-sector consultancy and innovation, which contribute to enhancing the economy and improving social welfare. We strive for academic excellence, collegial respect and freedom tempered by responsibility. The Technical University of Denmark (DTU) is a leading technical university in northern Europe and benchmarks with the best universities in the world.
