During 2005 approximately 2,500 MW of wind capacity was added in the United States, which brought installed wind capacity to about 9,150 MW. Although the total wind capacity in the United States is less than in some countries, wind energy has caught the attention of some utilities that depend on natural gas to generate power. There is evidence that wind(More)
The characteristics and effects of nonlinear loads in the commercial office environment are discussed. The interaction of distorted currents drawn by these loads with the power system are described. An approximate approach for evaluating potential problems within a given facility is discussed, which, while not rigorous, can be used as a screening tool by(More)
The objective of this paper is to present the modeling and analysis of a 1.7 Mva SMES-based voltage sag corrector devices. The topology of the SMES-based system and its response to an upstream fault are described. This paper details various modeling aspects of the device including methods to generate a triangular signal and an internal reference voltage.(More)
