摘要

目的

随着新能源发电大规模并网，电力系统一次调频需求日益增加，传统火电机组因调节性能不足面临严峻挑战。针对这一技术挑战，文章开展面向火电一次调频的双电层电容器（EDLC）储能系统研究。

方法

依托华能罗源电厂储能项目，基于3.0 V/

3400

F EDLC单体，完成了从单体选型、模组设计、簇集成到1 MW/30 s预制舱的全层级系统设计；搭建试验平台，开展了模组温升、单体循环寿命、高温耐久性等关键性能测试，并通过仿真验证了系统的一次调频响应能力。

结果

试验结果表明：30次/h最高调频频次下，模组极限温升仅21 ℃；常温90万次循环后容量保持率达75.86%，65 ℃高温下2万次循环容量保持率为82.47%；仿真显示系统功率响应延迟50 ms，输出精度偏差≤±2.1%，充放电折返时间仅60 ms。

结论

所设计的EDLC储能系统具备“快速折返、精确输出”的核心特性，可有效提升火电机组一次调频性能，为双电层电容在火电调频领域的规模化工程应用提供了完整的设计与试验依据。

Abstract

Objective

With the large-scale integration of renewable energy

the demand for primary frequency regulation in power systems is growing. Traditional thermal power units face severe challenges due to their insufficient regulation performance. To address this technical challenge

this study focuses on an electric double-layer capacitor (EDLC) energy storage system for thermal power primary fre

quency regulation.

Method

Relying on the energy storage project of Huaneng Luoyuan Power Plant

a multi-level system design—spanning cell selection

module design

cluster integration

and a 1 MW/30 s prefabricated container—was completed based on 3.0 V/

3400

F EDLC cells. An experimental platform was established to test key performance indicators

including module temperature rise

cell cycle life

and high-temperature durability. Finally

the primary frequency regulation response capability of the system was verified through simulation.

Result

The experimental results indicate that under a maximum regulation frequency of 30 cycles/h

the maximum temperature rise of the module is only 21 ℃. After

900000

cycles at room temperature

the capacity retention is 75.86%

while the capacity retention after

20000

cycles at 65 ℃ is 82.47%. Simulation results demonstrate that the system's power response delay is 50 ms

the output accuracy deviation is ≤ ±2.1%

and the charge-discharge turnaround time is only 60 ms.

Conclusion

The designed EDLC energy storage system exhibits the core characteristics of "fast turnaround and precise output"

which can effectively improve the primary frequency regulation performance of thermal power units. This study provides a comprehensive design and experimental basis for the large-scale engineering application of EDLCs in the field of thermal power frequency regulation.
