摘要

我国区域电网目前多采用联络线功率频率偏差控制(tie-line bias control，TBC)模式。这种以省为实体承担调频和实时功率平衡责任的控制模式不支持调频资源互济，不利于区域同步电网应对日益增加的新能源功率波动或大功率缺失风险。为在不打破“省为实体”的TBC频率控制模式前提下开展多省调频资源的互济，该文提出一种区域电网调频资源跨省互济机制以及支撑该机制的互联电网频率控制策略，可在买方、卖方省调及网调三方无需实时通信的情况下完成调频互济，满足调频互济对实时性与灵活性的高要求。结果表明，该机制和策略能减小区域控制误差及互联电网的频率偏差，实现区域电网内调频资源的优化配置。

Abstract

In China's regional power grids

Tie-Line Bias Control (TBC) mode is predominantly utilized. This control scheme

where provinces individually assume responsibility for frequency regulation and real-time power balance

does not allow sharing of frequency regulation resources

and is unable to cope with increasing uncertainty of renewable generation and risks of power losses. To address this issue without altering the existing TBC control framework

this paper proposes a mechanism for cross-provincial coordination of frequency regulation resources within a regional power grid

along with a supporting frequency control strategy for interconnected power systems. The proposed mechanism enables frequency regulation sharing among the buyer province

seller province

and regional grid operator without the need for real-time communication among the three parties

thereby meeting the stringent requirements for real-time performance and flexibility. Simulation results demonstrate that the proposed mechanism and strategy effectively reduce area control error and frequency deviation in the interconnected grid

achieving optimized allocation of frequency regulation resources within the regional power system.
