“Power entropy” can quantitatively reflect the characteristic difference of multi-time scale energy storage configuration. The power curve synthesized by two sinusoidal power curves is used to study the entropy difference and characteristics of main scenarios of energy storage applications such as frequency regulation, peak regulation and cross-season energy regulation. The results show that, power entropy can effectively reflect the difference of characteristics of energy storage for different time scales. For the scenarios of frequency regulation and peak regulation, using two sets of energy storage is better. For the scenarios that the difference between frequency and amplitude is less than 2 times, it is appropriate to apply a single set of energy storage. The research theoretically explores the methods and basis of multi-time scale energy storage configuration, reveals the essential differences of multi-time scale problems, it is helpful to form a scientific and optimal energy storage configuration scheme, scheduling scheme and optimization scheme.
