Adequacy Assessment of Wind Energy Conversion System through Simulating Wind Speed using Weibull Distribution

Abstract

In the electrical power market, nowadays wind energy is becoming a popular alternative to the conventional sources to meet the ever-increasing cumulative power demand due to it's eco-friendly, communal and commercial benefits. Unlike conventional, the electrical power generated from wind energy conversion system (WECS) acts differently as it is solely relying on the wind speed and site-specific. This paper focuses on simulating the behavior of the wind speed using Weibull distribution and calculates the power in associating the power speed characteristic of the wind turbine. The output power of the WECS is segregated to create multi-state WECS model. Adequacy assessment demands two state reliability model to estimate the adequacy of the generating system. Thus the multistate model is reduced to 2 state model using apportioning method and assess the reliability of the WECS. 15 MW wind farm is considered as the case study to validate the efficacy of the proposed methodology.
