“…Wind power also suppresses electricity prices for electricity more generally because hourly markets set prices at the margin. Because wind power is either delivered under contract or bids into the spot market near $0 given its low marginal cost (zero fuel costs), it lowers the spot (marginal) price for all electricity sales (27,28). A change in offshore wind power communication to match its promise is thus needed.…”

“…The initial diameters of the drag discs were estimated by the drag formulation: F = 1 2 C d ρv 2 A, in which F is the thrust force on the disc; C d is the drag coefficient which is set to 1.9 according to the DNV rule [40]; ρ is the air density; v is the wind speed at hub height; A is the area of the disc. The wind thrust force was calibrated in the small test section of the wind tunnel.…”

“…Adopting clean, renewable energy such as wind power is critical. Compared with onshore winds, worldwide offshore wind resources have proved to be more abundant and consistent, less visual, noise annoyance and variability on market price [1,2]. It is estimated that offshore wind could contribute to nearly 5.5% of the world's electricity by the year 2050 [3].…”

Directionality Effects of Aligned Wind and Wave Loads on a Y-Shape Semi-Submersible Floating Wind Turbine under Rated Operational Conditions

et al. 2017

Abstract:The Y-shape (triangular) semi-submersible foundation has been adopted by most of the built full-scale floating wind turbines, such as Windfloat, Fukushima Mirai and Shimpuu. Considering the non-fully-symmetrical shape and met-ocean condition, the foundation laying angle relative to wind/wave directions will not only influence the downtime and power efficiency of the floating turbine, but also the strength and fatigue safety of the whole structure. However, the dynamic responses induced by various aligned wind and wave load directions have scarcely been investigated comparatively before. In our study, the directionality effects are investigated by means of combined wind and wave tests and coupled multi-body simulations. By comparing the measured data in three load directions, it is found that the differences of platform motions are mainly derived from the wave loads and larger pitch motion can always be observed in one of the directions. To make certain the mechanism underlying the observed phenomena, a coupled multi-body dynamic model of the floating wind turbine is established and validated. The numerical results demonstrate that the second-order hydrodynamic forces contribute greatly to the directionality distinctions for surge and pitch, and the first-order hydrodynamic forces determine the variations of tower base bending moments and nacelle accelerations. These findings indicate the directionality effects should be predetermined comprehensively before installation at sea, which is important for the operation and maintenance of the Y-shape floating wind turbines.

Interactions between the design of short-term electricity markets in the CWE region and power system flexibility

et al. 2017

View full text Add to dashboard Cite

Short-term electricity markets are generally defined as markets that take place from the day-ahead stage until physical generation and consumption. These markets include dayahead, intra-day, and real-time balancing markets. In Europe, the first two are managed by power exchanges, while the third consists of reserve procurement and imbalance settlement and is operated by the local transmission system operator. Short-term markets are important tools to deal with net demand variability in the system, in which the need for flexibility is expressed and its provision is valorized. Due to the ongoing integration of variable renewables in the generation mix, the system's variability is increasing as a result of the limited controllability and predictability of those resources. As such, these markets become increasingly important. The contribution of this article is a comprehensive upto-date discussion of the key design parameters and functioning of all three short-term markets, and their impact on the demand for and supply of flexibility. An understanding of the design and its implications is useful to policy-makers who are considering changes to facilitate the integration, availability, or valorization of flexibility, while also contributing to the decision-making of flexibility investors and operators. The geographical scope is the Central Western European region, including the Belgian, French, German, and Dutch market zones.
