分布式储能在平抑间歇性电源的波动性、参与电力调峰、改善电能质量、提高供电可靠性等方面发挥着重要作用。如何量化评估储能系统的供能及调节能力,对于挖掘各类功率型储能和能量型储能组合配置的调节潜力以及分布式储能的优化配置都至关重要。文中针对目前常用的储能形式和装置,对各类储能的响应速度特性、功率调节特性等进行分析,在对影响储能系统调节能力的多种因素分析基础上,提出了一种基于模糊综合评判的储能系统调节能力评估模型,为不同储能组合模式、不同容量配置比例下,定量化评估分布式储能系统的供能及调节性能提供实用有效的方法。通过仿真算例验证所提方法的有效性。

Regulating ability analysis of distributed energy storage system based on fuzzy comprehensive evaluation

Distributed energy storages play an important role in suppressing the fluctuation of intermittent power supply, participating in peak shaving,and improving power quality and power supply reliability. How to quantitatively evaluate the energy supply and regulation ability of energy storage system is very important for tapping the adjustment potential of various power and energy storage combination configurations and optimizing the allocation of distributed energy storage. In this paper, the response speed characteristics and power regulation characteristics of various energy storages are analyzed with respect to the commonly used energy storage forms and devices. With an analysis of various factors affecting the regulation capacity of energy storage systems, an evaluation model of regulation capacity of energy storages based on fuzzy comprehensive evaluation is proposed to quantitatively evaluate the energy supply and regulation performance of distributed energy storage system under the circumstances of different energy storage combination modes and different capacity allocation ratios,and its effectiveness is verified by simulation examples.
