Difficulties Integrating Wind Generation Into Urban Energy Load
of Wind Generation on Xcel Energy system
Optimizing Power Plant Output for forecasted Load—Typically this involves scheduling
1) Generation is dependent on wind
Wind farm over 40 miles across and over 200 turbines
These are 2.3MW
Seimens turbines located near Adair, IA.
Blade Lengths are ~35 meters (~114 ft) long
Wake can propagate up to 700 meters (~2296 ft)
The Diameter is then over 70 meters (~230 feet
A rare, aerial photo of an offshore windfarm in Denmark clearly shows how turbulence generated by large turbine rotors continues to build with each successive row of turbines.
Without improvements in Communication with wind plant operatorsData at the Turbine Level& Modeling we head down a dangerous path if we plan on integrating even more wind on our systems.
