To eliminate grid fluctuations and consider battery degradation, Garmabdari et al. [ 23] introduced grid power fluctuations smoothing index and energy storage degradation factor, and optimized the size of the components in multi-generation systems with the total cost as the objective function.
This is mainly because the power generated by PV plays an important role in electricity charged by the battery system for FiT 1, while the amount of electricity stored by the battery from the PV system is far less than that from the power grid for FiT 2. Therefore, PV degradation has a great impact on the optimal battery capacity for FiT 1.
The state of charge influences a battery’s ability to provide energy or ancillary services to the grid at any given time. Round-trip eficiency, measured as a percentage, is a ratio of the energy charged to the battery to the energy discharged from the battery.
In this study, the BES's capacity degradation has been calculated when the annual operation of the system is terminated. Hence, it is not possible to consider that degradation in the operation. This approach is considered acceptable by several studies for optimal sizing of battery [1, 20, 21].
Considering the impact of battery degradation on the system operation over the service life of BESS, a MINLP model for the grid-connected PV-battery systems was proposed, which regarded the life cycle cost as the optimization objective.
