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.
