Abstract: Wind energy is available everywhere in abundance, tapping this energy and utilizing it optimally is the need of the day. Renewable energy sources, especially wind turbine generators, are considered as important generation alternatives in electric power systems due to their non-exhausted nature and benign environmental effects. In this paper present an Probabilistically evaluation of generating systems by collecting the historical wind speed data over one years for the wind farm location to determine the necessary parameters of the wind speed models for the particular site. The system reliability shows the availability and the power generation model. In this work the basic system reliability indices are calculated. This study shows the probabilistic analysis of wind power generation from wind turbine generators installed at geographic locations.
Keywords: Wind energy, reliability evaluation, WTG, probabilistic model.
