Composite generation and transmission system reliability evaluation incorporating two wind energy facilities considering wind speed correlation

This paper illustrates the effects on the load point and system reliability indices of a composite generation and transmission system of adding wind energy facilities with different degrees of wind speed correlation. The studies were conducted on the two test systems using a state sampling Monte Carlo approach. The analyses show the impacts of adding wind generating capacity at various locations in the two test systems and the effects on the load point and system indices of varying the wind penetration and the wind speed correlation levels. The studies presented illustrate the importance of considering wind speed correlation in the reliability assessment of composite generation and transmission systems containing large scale wind energy facilities.
