摘要:

本文提出了线性化的物理为基础的模型,锂离子电池,可以纳入电力系统经济研究的优化框架。所提出的模型是单粒子模型的线性近似,并且它允许表征影响电池操作的电池内部的物理过程的动态。目前,在锂离子电池储能系统(LIBESS)的运行和规划研究中广泛采用的简化的功率-能量模型导致了不可行的运行和误导性的经济评估,因此需要这种模型。与最近使用的基于非线性物理的模型相比,所提出的线性化模型在计算上是有益的。能源套利的应用程序是用来评估所提出的模型在一个简单的电力能源模型的优势。

英文摘要:

This paper proposes the linearized physics-based model of a lithium-ion battery that can be incorporated into the optimization framework for power system economic studies. The proposed model is a linear approximation of the single particle model and it allows to characterize dynamics of the physical processes inside the battery that impact the battery operation. There is a need for such model as a simplistic power-energy model that is widely employed in operation and planning studies with the lithium-ion battery energy storage system (LIBESS) results in infeasible operation and misleading economic assessment. The proposed linearized model is computationally beneficial compared with a recently used nonlinear physics-based model. The energy arbitrage application is used to assess the advantages of the proposed model over a simple power-energy model.
