Optimal control of offshore wind farm collector systems during outages: Harvesting the full potential of inter-array cabling

Ambitions to limit climate change are incentivizing the expansion of renewable energy. In particular, offshore wind energy is expected to grow rapidly. To harness the full potential of existing as well as prospected offshore wind farms, the limited capacity of the internal cable network of the offshore wind farm, called the collector system,...

Probabilistic downtime analysis for complex marine projects: A state-of-the-art model based on Markov theory to generate binary workability sequences for sequential operations

A marine operations encounters downtime if its operational limit is exceeded during project execution. Accurate information about the expected downtime during a marine project is important information in the tender phase of such a project. The purpose of this thesis is therefore to give insight in the available methods for downtime analysis in...

Investigation on Fault-ride Through Methods for VSC-HVDC Connected Offshore Wind Farms

Recently, there has been a fast development and deployment of wind energy to meet the increasing electrical power demand and to limit the use of fossil fuels. More and more wind farms are planned far from shore because of good wind condition and less visual impact. This is so called offshore wind farm (OWF). In such a situation, high voltage...
