TL;DR: In this article, the reliability characteristics in both probability and frequency of large electric utility application wind turbine generators together with their associated utility interface equipment were modeled and applied to a wind farm with a special AC/DC/AC interface.
Abstract: This paper is concerned with modeling the reliability characteristics in both probability and frequency of large electric utility application wind turbine generators together with their associated utility interface equipment. A computationally efficient algorithm is developed and applied to a wind farm with a special AC/DC/AC interface currently under design. The effects of various wind turbine/interface system component forced outage rates on the expected annual energy output of the farm is examined.

TL;DR: In this paper, the authors assess the effects of various parameters on the performance of the bulk transmission system outage data and identify the dominant parameters which are generic to any geographic, region.
Abstract: The pooling of bulk transmission system outage data has been a topic of recent interest. However, before analysis of pooled data should take place, there is a need to assess the effects of various parameters on the performance of the bulk transmission system. Identification of the dominant parameters which are generic to any geographic, region is an important step in understanding the effects of pooling outage data on the calculated indices.

TL;DR: The correct approach is to launch an attack on present forced outages, reduce them to figures comparable with best world figures and plan the forward plant programme on that assumption.
Abstract: The amount of plant needed to meet the load in an electric utility is very dependent on the forced outage rates. In a utility that presently experiences high forced outage rates, there is a danger that future plans will use such high figures. The correct approach is to launch an attack on present forced outages, reduce them to figures comparable with best world figures and plan the forward plant programme on that assumption. This paper describes such a programme in some detail.
TL;DR: The assumption of independence is fundamental to the calculation of production costs and reliabiity indices in the Calabrese method of calculating loss of load probability (LOLP) as mentioned in this paper.
Abstract: Most of the utility generation planning models make the assumption that outages are independent events. The reason behind this assumption is two- fold: independence allows the calculations to be made using fairly simple algorithms and the utilities have not generally collected data on the effect of outages on system forced outage rates. The Calabrese method of calculating loss of load probability (LOLP) assumes independence of outages. In the popular Baleriaux- Booth algorithm and in the method of cumulants, the assumption of independence is fundamental to the calculation of production costs and reliabiity indices.
