摘要:

为了解决由可再生能源接入驱动的系统频率挑战,设计了在设备层面的先进控制策略,以在扰动后提供有效的频率支持。然而,通常依赖于基于能量的性能指标,这些方法无法保证系统频率约束,如频率谷底和最大频率变化率(RoCoF)。此外,本地设计的频率支持无法最小化整体系统成本以维持频率稳定性。另一方面,引入了频率约束系统调度的概念,将频率动态约束纳入系统经济优化,从而使频率要求能够以最低成本维持。然而,这些工作依赖于频率动态指标的分析近似,这些近似在数学上复杂且倾向于为IBR头寸要求的近似过度保守。

英文摘要:

To address system frequency challenges driven by the integration of renewable generation, advanced control strategies are designed at the device level to provide effective frequency support following disturbances. However, typically relying on energy-based performance metrics, these methods cannot guarantee the system frequency constraints such as frequency nadir and maximum Rate-of-Change-of-Frequency (RoCoF). Moreover, locally-designed frequency support cannot minimize the overall system cost to maintain frequency stability. On the other hand, the concept of frequency-constrained system scheduling is introduced, which incorporates frequency dynamic constraints into the system economic optimization, so that frequency requirements can be maintained with minimum cost. However, these works rely on analytical approximations of the frequency dynamic metrics, which are mathematically complicated and tend to be over-conservative for the approximation of IBR headroom requirements.
