Battery Degradation Maps for Power System Optimization and as a Benchmark Reference
It provides a scalable, convex representation of battery degradation for power system optimization, useful for researchers and engineers modeling battery aging.
The paper introduces degradation maps to model battery capacity loss as a function of control actions and state of charge, enabling tractable optimal control and benchmarking of battery technologies.
This paper presents a novel method to describe battery degradation. We use the concept of degradation maps to model the incremental charge capacity loss as a function of discrete battery control actions and state of charge. The maps can be scaled to represent any battery system in size and power. Their convex piece-wise affine representations allow for tractable optimal control formulations and can be used in power system simulations to incorporate battery degradation. The map parameters for different battery technologies are published making them an useful basis to benchmark different battery technologies in case studies.
