Applicants are invited for an Experienced Researcher (post-doc) position in the Marie-Curie "Multi-terminal DC grid for Offshore Wind", Initial Training Network (MEDOW ITN) at ALSTOM RENEWABLES.
This position is full-time and fixed term for 12 months. Ideally, the successful candidate will commence employment in March 2015. To utilise the expertise of the ITN, and to facilitate multi-disciplinary collaboration, the researcher will have the opportunity for international secondments.

Description

A DC grid based on multi-terminal voltage-source converter is a newly emerging technology, which is particularly suitable for the connection of offshore wind farms. Multi-terminal DC grids will be the key technology for the European offshore SuperGrid. In this project, DC power flow, DC relaying protection, steady state operation, dynamic stability, fault-ride through capability, and impacts of DC grids on the operation of AC grids and power market will be studied. Systematic comparison of DC grid topologies and stability control strategies will be carried out. DC grids for offshore wind power transmission and onshore AC grid interconnection will be investigated. Operation and control will be evaluated using various simulation platforms and experimental test rigs. The achievements from the project will contribute to integrating offshore wind power into the onshore AC grids in European countries and for the European Super Grid.

The Experienced Researcher will carry out a project entitled "Integration of offshore wind into DC grids". (S)he will be based at Alstom Renovables in Barcelona and will be co-supervised by staff at CITCEA-UPC (Universitat Politècnica de Catalunya).

The MEDOW project is co-ordinated by Cardiff University, UK.
