主 题：Conditional value at risk reliability second life batteries
摘 要：With the growing adoption of Electrical Vehicles(EVs),it is expected that a large number of on-board Li-ion batteries will be retired from EVs in the near *** batteries will typically retain 80%of their initial capacities and can be recycled as second life batteries(SLBs).Although the capital costs of SLBs are much cheaper,their operational reliability is an important concern since used batteries may suffer from a higher failure *** paper aggregates brand new batteries and SLBs together to improve power system’s operating performance with renewable energy *** the context of a day-ahead and intra-day dispatch framework,a two-stage coordinated optimal scheduling method is ***,the energy cost of brand-new batteries and SLBs is calculated based on detailed battery degradation model,and the reliability of batteries is modeled based on the Weibull ***,Conditional value at risk(CVaR)criterion is applied to evaluate the risk induced by intermittent renewable power output,load demand variation and SLBs failure *** tests demonstrate the effectiveness of the proposed method.
