摘要

针对"火电灵活性改造试点项目"目标要求的提升机组爬坡能力开展研究。首先

结合试验结果分析了现有火电机组具备的AGC响应能力

其与预期目标之间仍存在一定的差距。在对机组协调优化控制技术、基于机组自身蓄能的负荷调节技术和基于储能的负荷调节技术进行分析论述的基础上

提出利用联合储能系统提升机组AGC响应能力

并对其运行特点、热力特性、项目投资等进行了分析。联合储能系统可实现与纯电池储能方案接近的调节品质

具有投资较低、安全性更高等特点

值得推广。

Abstract

This paper focuses on increasing power plants' flexibility of fast ramp-up ability. At first

combining with the experimental results

the actual AGC response ability of the current thermal power units are analyzed

it finds out that there is still a certain gap between the existing thermal power units and the expected targets. On the basis of discussing the coordinated optimal control technology

the load regulation technology based on the unit's self energy storage ability

and the load regulation technology based on energy storage

a united energy storage system is proposed to enhance the AGC response ability of the units. Moreover

the running property

thermal characteristics and project investment are analyzed in detail. The results show that the united energy storage system can realize the regulation quality close to the pure battery energy storage scheme

and has the characteristics of lower investment and higher safety

so it has a strong promotion significance.
