FAST has the capability of modeling a wide range of offshore wind system configurations including shallow water, transitional depth, and floating systems.
NREL Researchers Advance Wind Energy Systems Engineering
In recent years, researchers from the National Renewable Energy Laboratory (NREL) have been making progress in multiple avenues of wind systems engineering. This includes the study of how to integrate wind energy engineering and cost models across wind plants, finding the important interactions between various subsystems to achieve a better understanding of how to improve system-level performance and cost reductions, and hosting international, collaborative workshops.

Report Says Western Grid Can Weather Disturbances under High Renewable Penetrations
A new report finds that with good system planning, sound engineering practices, and commercially available technologies, the Western Interconnection can withstand the crucial first minute after grid disturbances with high penetrations of wind and solar on the grid. More
Guidelines Help Manage Risks and Encourage the Development of Marine and Hydrokinetic Technologies
To help reduce the risks of marine and hydrokinetic industry failures and advance the development of current and new technologies at a lower cost and faster pace, the U.S. Department of Energy (DOE) and NREL created a framework that provides a risk management methodology to identify and reduce risks during all stages of technology development and particularly prior to demonstration activities.

Models and Tools
NREL's WIND Toolkit Provides the Data Needed to Conduct Power System Simulations
Researchers who conduct regional wind integration studies in the United States need to perform simulations of how the power system will operate under high-penetration scenarios. The wind data sets that are used in these studies must realistically reflect the ramping characteristics, spatial and temporal correlations, and capacity factors of the simulated wind plants, and must be time-synchronized with available load profiles. NREL is providing a vehicle to meet these requirements: the Wind Integration National Dataset Toolkit. More
FAST Revs Up with a v8
Offshore and land-based wind turbine systems are subject to complex and harsh operating conditions. When designing systems for such conditions, wind technology developers need powerful tools. One such tool is the computer-aided engineering tool called FAST, developed and supported by NREL. The laboratory has recently released an improved and expanded version of FAST that features a new modularization framework that boosts the tool's power, robustness, and flexibility. More
Wind Career Map Shows Wind Industry Career Opportunities, Paths
In 2014, DOE, in conjunction with NREL, created a Wind Career Map—the first of its kind in the wind industry—to inform people interested in wind energy career opportunities. More
