论文摘要
本文提出了基于线性化的锂离子电池的线性化模型,可以将其纳入电力系统经济研究的优化框架中。提出的模型是单个粒子模型的线性近似,它允许表征电池内物理过程的动力学,从而影响电池操作。需要像简单的功率能量模型这样的模型,该模型被广泛用于使用锂离子电池储能系统(LIBESS)进行的运营和计划研究,从而导致操作和误导性经济评估。与最近使用的基于非线性物理学的模型相比,提出的线性化模型在计算上是有益的。能源套利应用用于评估所提出模型的优势,而不是简单的功率能量模型。
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.
