Microgrid Battery Energy Storage Capacity Configuration Optimization Model

Aiming at the problem that the battery energy storage equipment in microgrid is too fast and the capacity configuration is too high, this paper establishes an optimal configuration model of battery energy storage capacity in microgrid considering life loss, and proposes a cost calculation method of battery energy storage life loss based on fixed daily cycle times. This method combines the idea of piecewise linearization and scene analysis method, which can effectively extend the life of battery energy storage by optimizing the discharge depth and daily cycle times of battery energy storage. Finally, the effectiveness of the new model under different uncertainties and different unit prices of battery energy storage is verified by an example.
