Wind Power MotivationWhat is the Wind Power Potential in the US?• Onshore capacity ~10TW, offshore ~1TW

What are Wind Power Challenges?• Onshore/Offshore
– Variability in wind speed– Radar interference– Transmission cost– Harsh environment reliability– Scaling up size for more power
Why is Simulation Important?• Electrical
– As wind power is ramped up, the voltage and frequency of the grid becomes less dependent on fixed sources and more dependent on wind dynamics.
• Mechanical– As turbines increase in size and number, aerodynamic efficiency, securing foundations and identifying vibration becomes very important.
• Reduce Risk / Increase Reliability– Evaluate performance before issues arise
