Enhancing biodiversity in offshore windfarms in the North Sea

De Rijke Noordzee (DRN) is a Dutch organization with a mission to enhance nature utilizing the opportunities which offshore wind farms offer. The organization is currently working on several nature enhancement projects in offshore wind farms in the Dutch part of the North Sea. However, DRN’s mission to enhance biodiversity does not stop at the...

Supply Chain Simulation of Offshore Wind Farm Monopile Installation: Performance of different supply chain configurations under dynamic weather influences

A monopile installation project consists of the whole process of loading monopiles to vessels, transporting monopiles to the wind farm and drilling monopiles in the seabed. Each installation project has different characteristics as the weather at the installation location, the distances to the suppliers and the vessels that are available differ...

Technical performance of different DC CB technologies for future HVDC Grids

Multiterminal dc (MTDC) network is preferred due to its reliability, security of supply and flexibility. However, MTDC network also comes with the protection challenges resulting from dc faults. Hence, the dc circuit breaker (DC CB) is imperative in such a network. In these recent years, several DC CB technologies have been proposed and...

Coordinative performance of HVDC circuit breakers in MTDC grids

The objective of this paper is to investigate the coordinative performance of different types of high voltage DC (HVDC) circuit breakers (CBs) in multi-terminal DC (MTDC) grids. Several different HVDC CB technologies are emerging as a solution for the protection of offshore MTDC grids. There is a need for coordinative operation between different...

Geintegreerd offshore aquacultuur windmolenpark ontwerp: Multi-aquacultuur in een offshore windmolenpark Samen met onderzoekslaboratorium en museum

Abstract – The presented study focusses on the current situation of the European flat oyster (i.e., Ostrea edulis) within an ecosystem, its development and decline during past centuries and the habitat conditions nescacary to survive. Among these conditions substrate quality proofed to be an important factor for the colonization of oyster larvae...

Innovative power system event-detection and synchronous plant emulation technique for large wind power plant

The subject matter of this thesis report investigates a synthetic inertia and dynamic stability technique for grid inter-connection of large VSC-HVDC connected offshore windfarms. Assuming traditional load frequency control on the AC grid for the short-term reallocation of power generation resources due to load disturbances, this technique ties...

Multi-objective optimization of wind farm layouts: Complexity, constraint handling and scalability

Currently, Offshore Wind Farms (OWFs) are designed to achieve high turbine density so as to reduce costs. However, due to wake interferences, densely packing turbines reduces energy production. Having insight into optimized trade-offs between energy production, capital investment and operational costs would be valuable to OWFs designers. To...
