Despite widespread public support for renewable energy development, the siting of wind energy facilities can prove problematic due to opposition from surrounding communities. I propose a unifying framework to explain community response to wind energy development – showing how concepts from environmental sociology related to local biophysical and socioeconomic conditions...
The primary objective of a grid is to maintain a balance between generation and load. If these quantities are not in balance with each other, severe damages such as voltage fluctuations, low power quality, power outages or even cascaded blackouts may occur. Hence one of the primary factors that holds...
The effects of selected atmospheric variables on the power output
of a DOE Mod-2 horizontal-axis wind turbine are studied. Particular
attention is focused on unsteady, nonuniform flow conditions
within the rotor disc as represented by vertical profiles measured at
adjacent meteorological towers. Primary variables are wind speed,
wind direction and...
Development of wave and offshore wind-based marine renewable energy is anticipated on the Outer Continental Shelf (OCS) off Oregon and much of the Pacific Northwest in the coming decade. Multiple issues related to environmental considerations and information needs remain for these emerging industries. The Oregon Marine Renewable Energy Environmental Science...
This thesis presents and examines the concept that the output of a wound-rotor induction generator (WRIG) can be limited by means of linking to external impedances for wind-turbine generating system application. An 80kW-WRIG is simulated as a model to examine the control of the output power vs. speed characteristic. Model...
Over the last decade, wind penetration in the Pacific Northwest has increased rapidly. The variable nature of this massive new resource has increased stress on the hydropower resource to the point where system limits are currently being reached. In order to cultivate continued growth of the wind energy industry both...
Generation of electricity from the wind is becoming increasing popular as an
environmentally responsible resource. Current methods for generating electricity from
the wind involve the use of fixed-speed generators. However, the use of variable-speed
generators increases the amount of energy that can be extracted from the wind.
Most variable-speed technologies...
The fast growth of wind energy utilization has necessitated research into wind energy integration. Due to the variable nature of wind and the forecasting challenges, it is desirable to utilize wind energy alongside energy storage sources for reliable wind energy integration. This work details the design of a 25 kW...
