Wind power costs expected to decrease due to technological progress

Air emissions due to wind and solar power.

Renewables portfolio standards (RPS) encourage large-scale deployment of wind and solar electric power. Their power output varies rapidly, even when several sites are added together. In many locations, natural gas generators are the lowest cost resource available to compensate for this variability, and must ramp up and down quickly to keep the grid stable, affecting their emissions of NOx and C...

Wind Power Impacts on Electric Power System Operating Costs: Summary and Perspective on Work to Date

Voltage Deviation of Wind Power Generation due to Wind Velocity Change

This paper treats an induction machine as a wind power generator, and voltage deviation due to wind velocity change is simulated by a dynamic stability calculation program. The ac bus voltage connected to the wind generator highly depends on the wind velocity variation. Then author actually measured the wind velocity which is used for the simulation. This paper shows 1 second sampling data of t...

Incidental Changes to Training Capabilities Due to Technological Improvements

During the development and enhancement of simulator systems, new technologies are incorporated to improve the training capabilities of the system. The degree to which changes to the simulator system improve training capabilities in anticipated areas is of primary interest; however, an evaluation of benefits from newly incorporated technologies should consider the impact on training capabilities...
