| 摘要: |
| 储能系统的投资过程主要包括初始购置、运维和置换三个阶段，不同的应用工况将对电池储能系统的寿命衰减速率产生差异化影响，进而影响其成本投入过程，也是储能系统经济评估中的必要考虑因素。面向储能系统的经济性动态评估，首先定义温度、倍率、放电深度(Depth of Discharge, DOD)、充放电频次等作为储能工况特征量。基于工况特征量与电池寿命损耗之间的关联关系，建立了计及工况特征参量的储能系统出力模型和成本模型。基于全寿命周期成本模型(Life Cycle Cost, LCC)和遗传算法，分析了工况特征量在储能成本评估中考虑的必要性及其影响程度。最后，在平抑光伏波动和负荷侧削峰填谷两种工况下展开算例分析，验证了在储能规划过程中考虑工况特征量的必要性。该研究将为储能规划阶段的经济性评估提供理论依据与数据基础。 |

| Abstract: |
| The investment progress of BESS includes 3 parts, initial purchase, operation and replacement. The working conditions will have different effects on the life decay rate of BESS, and then affect the investment process of BESS. So it’s necessary to consider the characteristics of the operating conditions in dynamic economic evaluation of BESS. Firstly this paper defines temperature, rate, Depth of Discharge (DOD), the frequency of charge/discharge as condition characteristic parameter of BESS in BESS-oriented economy dynamic assessment. Based on the relationship between condition characteristic parameter and battery life loss, it builds the output model and the cost model of BESS considering the characteristic parameters of the operating condition. Then, based on the Life Cycle Cost (LCC) model and genetic algorithm, it analyzes the necessity and influence of operating conditions on the economic evaluation of BESS. Finally, it carries out example analysis under two operating conditions, i.e. stabilizing the output fluctuation of PV power station and load peak shaving. The necessity of considering the operating condition characteristics in the process of BESS planning is verified. The research will provide theoretical basis and data base for economic evaluation of BESS in the stage of planning. |
