Architecture and Interconnection of Offshore Wind Farms.

Biography: Jonathan received a secondary education from Carndonagh Community School and graduated from University College Dublin in 2012 with a BSc in Engineering Science, he then continued his education at UCD and graduated from the ME in Energy Systems in 2013, achieving first class honours. His ME research project which was conducted under the guidance of Professor O’Malley in the area of Demand Response, involved a case study determining the potential for data centres to capitalise on electricity price variations globally, through moving their workload across the world, following cheap and low CO­2 intensity electricity generation.

He commenced his PhD in UCD in September 2013, within the Electricity Research Centre (ERC). His research interests include future offshore wind farm design and optimisation, renewable generation systems and energy efficiency.

Jonathan Ruddy is funded through the SEES Cluster, supported by Science Foundation Ireland under Grant Number SFI/09/SRC/E1780.

Project: Architecture and Interconnection of Offshore Wind Farms.

Large off-shore wind farms located at a significant distance from the shore are envisaged as a solution to achieving renewable energy targets while also satisfying environmental and social concerns. However off shore wind farms present new challenges and opportunities as the choice of architecture (turbines, generators, power electronics and interconnection), is very much influenced by concerns of reliability and maintenance. In particular evolving power electronics technologies could facilitate new forms of control, and interconnection for the wind farm and offer new possibilities in the provision of network support. The aim of the research is to investigate different configurations for off-shore wind farms using modelling approaches, investigate new control strategies, and to compare and contrast the performance of the different architectures particularly in terms of reliability, grid interface, fault tolerance and network support.

Keywords: Offshore wind, power electronics, interconnection, HVDC, reliability.
