Abstract

An extended use of renewable energies and a trend towards increasing energy consumption lead to challenges such as temporal and spatial decoupling of energy generation and consumption. This work evaluates the possible applications and advantages of hybrid energy storage systems compared to conventional, single energy storage applications. In a mathematical approach, evaluation criteria such as frequency, probability of power transients, as well as absolute power peaks are combined to identify suitable thresholds for energy management systems on a multi-timescale basis. With experimental load profiles from a municipal application, an airport, and an industrial application, four categories, clustering similar roles of the VRFB and the SC, are developed.

电网应用中混合储能系统多时间尺度分类方法的发展
可再生能源的广泛使用和能源消费增加的趋势导致能源生产和消费的时空脱钩等挑战。这项工作评估了混合储能系统与传统的单一储能应用相比的可能应用和优势。在数学方法中,评估标准如频率,功率暂态概率,以及绝对功率峰值相结合,以确定在多时间尺度基础上的能源管理系统的合适阈值。根据市政应用、机场和工业应用的实验负载概况,开发了四个类别,聚集了VRFB和SC的类似作用。
