  1. Renewable Energy Research Laboratory University of Massachusetts Anthony L. Rogers, Ph.D.

  2. Mechanical and Industrial Engineering Dept. Research Offshore wind power (UMass, MIT, WHOI consortium) Hybrid power systems (wind, PV, diesel) System models Wind resource assessment Aerodynamics (wind tunnel, CFD) Funding: MTC, NREL, GEWind, DOE Education Two graduate wind energy courses One graduate solar energy course Consulting All renewable technologies, policy issues Renewable Energy Research Laboratory

  3. 25% annual growth worldwide Europe leads the way: 23 GW US: 4.6 GW 660 kW – 2000 kW (up to 5 MW) (160 - 360 households each) Tall: 160 – 260 feet high hub (50-80 m) 3 blades, 130-260 ft diameter (40-80 m) Becoming economically competitive Wind Turbines TodayMegawatt-scale Turbines

  4. Cost of energy reduction Weight reduction O+M cost reductions Mechanical load reduction Fatigue - main design driver Aerodynamics Controls Sensors Component efficiencies Noise reduction Offshore systems Efficient wind resource estimation Entrepreneurial Opportunities

  5. UMass research wind turbine 250 kW, two bladed Constant/variable speed Advanced power electronics Advanced control / design options Yaw damper Two-bladed turbine issues Advanced variable speed control Control Dynamics Research

  6. Need long-term mean wind speeds, directional behavior, turbulence, wind speed distributions Issues Time, cost, uncertainty Technologies Towers SODAR LIDAR RADAR Resource Assessment

  7. More wind offshore 10-70 ft depths Pile foundations in sea bed More costly Europe has numerous offshorewind farms Issues O & M costs Wave load prediction Offshore Wind Power

  8. The future of wind power Vast wind resource Not visible from shore Research topics Power transmission Anchoring O & M Dynamics Cost reduction Hydrogen generation Far-Offshore Wind Power

  9. Isolated island and village power systems Complicated systems Usually remote from technicians UMass research System modeling Implementation issues System control Design studies Future issues Grid-scale energy storage Hybrid Power Systems

  10. The future of clean energy systems Hydrogen Clean burning, derived from water using renewable sources Use in internal combustion engines and fuel cells Dispatchable for power generation Useful as transportation fuel Wind/hydrogen system issues Cost Integration with wind generation Part load operation System modeling issues UMass Research Wind / hydrogen bus system design issues Floating offshore wind / hydrogen systems Renewable / Hydrogen Systems
