钛酸锂电池城区电网储能系统经济性分析模型

Economic Analysis of Urban Power Grid Energy Storage System Based on Lithium Titanate Battery

以储能系统全寿命周期内收益最大化为目标,考虑钛酸锂电池的循环寿命及放电深度对储能系统成本的影响等因素,建立储能系统收入模型和全寿命周期年均成本模型,在此基础上建立基于钛酸锂电池的城区电网储能系统经济性评价模型。算例分析结果表明,该模型能够实现城区电网中钛酸锂电池储能系统的成本控制,可在寿命周期内实现预期的经济效益。

In order to maximize the revenue of energy storage system throughout its life cycle,a revenue model and a life cycle cost model of energy storage system were established considering the influence factors of the cycle life and discharge depth of lithium titanate battery on the cost of energy storage system,and based on it,an economy evaluation model of urban grid storage system was developed based on lithium titanate batteries.The case analysis shows that the model can realize the cost control of the lithium titanate battery energy storage system in the urban grid,and achieve the expected economy benefit in the life cycle.
