Aimed at the problems of fast loss and high capacity configuration of battery energy storage equipment in microgrid,an optimal configuration model of battery energy storage capacity of microgrid considering life loss is established in this paper.In addition,a cost calculation method for the battery energy storage life loss based on fixed daily cycle times is also proposed.This method combines the piecewise linearization idea and the scenario analysis method,and it can effectively extend the lifetime by optimizing the discharging depth and daily cycle times of battery energy storage.Moreover,considering the uncertainties in wind power output and load power,a two-stage robust optimization model is introduced,which is further solved by the column-and-constraint generation algorithm.Finally,the effectiveness of the novel model under different uncertainties and different unit prices of battery energy storage is verified by numerical examples.
