摘要
"功率熵"能够定量反映多尺度储能配置的特性差异.采用 2 种正弦功率曲线合成的功率曲线,重点研究了调频、调峰以及跨季节调节等储能应用主要场景的熵值差异和特性.结果显示:功率熵能够有效体现不同时间尺度储能特性的差异;调频、调峰 2 种调节类型宜采用 2套储能组合配置;对于频率和幅值差异在2 倍以内的 2种调节类型,则宜采用1 套储能配置整体调节.该研究从理论方面探索了多时间尺度储能配置的方法和依据,揭示了多时间尺度问题的本质差异,有助于形成科学的最优储能配置、调度和优化方案.
Abstract
"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.
