摘要:

基于熵理论建立储能系统功率的熵值分析方法与系统中储能的多项关键指标,如功率、时长、容量等,均有关联并存在一致的正相关关系,可以综合反映系统调节能力的功能。本工作在以往研究的基础上,研究并提出了“功率熵”体系下的系统调节能力标定方法,并结合特例对应用该方法指导系统储能优化配置进行了探讨。得出结论,一是特定能源系统的功率熵存在最大和最小值,可分别体现系统中储能提供的最大调节能力以及系统最低调节能力需求,案例中不同配置方式熵值差异19%。二是随着储能个数的增加,系统功率熵的最小值逐渐降低,并趋近于某一极限值,小型储能装置可作为优先调度的单元。三是功率熵受选取的标准化时间(T0)影响,但对于储能配置结果的影响将随着T0趋于0而快速收敛。综上,功率熵能够体现不同储能配置之间的差异,在储能配置优化方面有参考意义。

Abstract:

Inspired by the thermodynamic concept of Clausius entropy, power entropy can be used to assess the adjustment ability of energy systems. Power entropy exhibits a consistent positive correlation with key energy storage indicators, such as power, duration, and capacity. Building on previous research, this study proposes a calibration method for evaluating system adjustment ability within a power entropy framework and discusses its application in optimizing energy storage configurations under specific conditions. The results demonstrate that under different energy storage configurations, the system power entropy decreased by 33%. The system optimization progresses as the power entropy increase introduced by the energy storage decreases, which corresponds to reduced redundancy in the energy storage regulation performance. The power entropy concept provides a new idea for the optimization of energy storage configurations in future power systems and the optimization of multiple energy forms in integrated energy systems.
