Probability density functions for power output of Wind Electric Conversion Systems

Abstract

Probabilistic models for the power output of Wind Electric Conversion Systems (WECS) are considered. Wind speeds are modeled using Weibull distribution and probability density function for the power output of WECS is derived using the transformation theorem. Variable portion of the power output characteristic is modeled using different functions and the results are compared. Probability density functions for the combined power output of two, four and eight systems are presented and discussed.
