摘要

特高压输电工程逐步推进导致单一元件故障所造成功率失衡数量不断增加，可再生能源大规模接入导致常规机组容量占比持续降低，频率稳定控制攻防两端此消彼长，频率稳定问题凸显；而不断丰富的源网荷侧频率响应控制手段需要更好地协调，以充分发挥其控制效能从而提升频率稳定水平。通过频率响应控制视角下未来电网的结构与形态分析，明确了频率响应控制资源需要精细化管理与控制，指出需要开展动态视角下的频率响应运行调度和频率响应资源集中统一协调控制等理论的研究工作，为频率响应调节资源的规划、计划与调度和多类主体参与频率响应控制提供参考，从而提高系统整体频率响应能力，提升大扰动下的频率稳定抵御能力。

Abstract

As the development of ultra-high voltage (UHV) AC and DC transmission system in China

the quantity of unbalanced power caused by a single element fault will continue to increase. The large-scale renewable energy integration will keep decreasing the capacity ratio of conventional thermal units. Of both ends on the floor in frequency response control

the "offense" will be strengthening while the "defense" be lessening

and the frequency stability have become outstanding. On the other hand

the ever-richer frequency response control measures on "source-grid-load" side should be coordinated better

to make full use of their control performance so as to improve frequency stability level. Through analyzing the structure and shape of future grid from the perspective of frequency response control

it is clear that frequency response control resources need more refined management and control

and the relevant theory should be progressing with time. It is pointed out that the research of dispatch of frequency response from the dynamic perspectives and centralized and unified coordination and control of frequency response control measures should be developed. This will provide the references for planning

scheduling and dispatching of frequency response control measures and the participants of kinds of subject in frequency control. So

the frequency stability defense capacity will be reinforced with enhanced system frequency response control ability.
