Assessing Modeling Fidelity for Long-Term Battery Energy Storage Planning: Operation, Degradation, and Temporal Representation
The study tested how different modeling choices—like battery degradation mechanisms and temporal resolution—affect long-term battery energy storage planning over 20 years. It found that no single fidelity is best; the required level of detail depends entirely on what outcome you want to preserve, such as cost, replacement timing, or energy adequacy.
