Based on the cumulative failure probability equality principle, this paper considers the relationship between the load and the battery life distribution, and constructs a reliability model for the parallel subsystem of the battery pack when a single battery fails, and then compares the lifetime and reliability as a function of load and cell design. The result proves that the k-out-of-n system approaches closed to the parallel subsystem of the power battery pack.展开更多

This paper presents a methodology to evaluate the EEG as well as overall LOLP (loss of load probability), which is an index for system reliability of multi-area interconnected systems with wind generators, as well as conventional fossil fuel based generating units. The proposed model is also capable of tracking the energy export incorporating the multi-state probability model for wind generator which output varies with time and season.展开更多
