Modeling, Monitoring and Control of Wind Turbine Drive-trains

submitted by: RASEIBoulder
Summary: The wind turbine drive‐train is an integral part of the turbine that converts rotational kinetic energy from the wind to electrical energy. Ensuring reliable and robust operation of the drive‐train necessitates developing an accurate dynamic response model that includes its aero‐dynamic interaction with the wind, torsional and translational responses of its mechanical components, as well as electro‐mechanical interaction at the generator. This presentation will describe a...

Rotational Kinetic Energy as Power System Service: Assessing The Role of Wind Farms

submitted by: RASEIBoulder
Summary: The electric power system is currently composed of generators with large spinning masses whose speeds are tightly coupled together. These masses offer a store of rotational kinetic energy that naturally gives inertia to the average speed of the system. This inertia offers a first line of defense that is tapped during sudden power imbalances. Installing a large fleet of wind farms will result in hours of the year when many traditional generators are turned off. The result may be a...

Investigating Structure Variation of Electrode Materials for Lithium Ion Batteries

submitted by: RASEIBoulder
Summary: Improving energy density, power density, cycle life and safety and decreasing cost of current Li-ion batteries are highly desirable for the applications of advanced portable electronic devices, electrical tools, electrical vehicles, storage batteries for renewable energy, and stationary batteries for smart grids. Understanding lithium storage mechanism and structure-property relationship across length scales are essential for rational design of new materials. Here we report our...

Control of Wind Turbines: Accomplishments and Continuing Challenges

submitted by: RASEIBoulder
Wind energy is recognized worldwide as cost-effective and environmentally friendly and is among the world's fastest-growing sources of electrical energy. Despite the amazing growth in global wind power installations in recent years, science and engineering challenges still exist. Megawatt wind turbines are large, flexible structures that operate in uncertain, time-varying wind and weather conditions and lend themselves nicely to advanced control solutions. Advanced controllers can help...

Photovoltaics Technology: No Longer an Outlier

submitted by: icamp2012school
Larry Kazmerski, National Renewable Energy Laboratory Solar energy from photovoltaic devices has been around since the early days of the space race, but historically has not had a substantial impact on our global energy scheme. Is that now changing? Dr. Larry Kazmerski is the executive director of Science & Technology Partnerships at the National Renewable Energy Laboratory (NREL) in Golden, CO. He has worked at NREL for over 30 years and was previously the director of the National...
