Reliability of transmission networks – Impact of EHV underground cables and offshore networks for wind energy


Project Description

For the future, several developments of the power system are expected. Offshore, a large-scale expansion of wind generation will be implemented. This wind energy will be collected and transmitted to the shore by an offshore grid. Onshore, the transmission network needs to be reinforced to transmit the power to the main load centres. Traditional overhead lines are facing increasing opposition from local society, such that underground extra-high voltage cables are a promising alternative. As these new developments will influence the reliability of the power system, it is of importance to thoroughly study their impact. In this research, the reliability of EHV underground cables and offshore networks for wind energy is analysed, from the reliability of the individual components to the impact on the reliability of the power system as a whole. Mitigation measures to improve the reliability of power systems with EHV cables and offshore networks are suggested and their effects are assessed. The methods applied in this research show how the reliability of other future developments of power systems can be analysed as well.

B. W. Tuinema

Bart W. Tuinema was born in The Hague, The Netherlands, in 1984. He received his B.Sc. and M.Sc. degrees from Delft University of Technology, Delft, The Netherlands, in 2007 and 2009 respectively. In his M.Sc. research he studied the reliability of offshore networks for wind energy and the impact on the reliability of onshore power systems. In 2010, he joined the Intelligent Electrical Power Grids (IEPG) group of the Electrical Sustainable Energy (ESE) department at Delft University of Technology as a Ph.D. researcher. In his Ph.D. research, he studied the reliability of power systems with respect to new developments like EHV underground cables and networks for large-scale offshore wind energy. He is currently working in the same group as a postdoc researcher and is involved in teaching activities, the MIGRATE project (Massive InteGRATion of power Electronic devices) and TSO2020 (Transmission and Storage Options for 2020).
