AI 中文摘要
将来自多个供应商的逆变器型资源（IBRs）整合到电力系统中颇具挑战性，因为它们的控制器通常是独立设计的，几乎没有协调。针对该问题，本文提出一种基于块对角优势（BDD）理论的IBRs分散控制综合框架，可确保多IBR电力系统的小信号稳定性。该方法利用电网频率响应，实现分散式多输入多输出（MIMO）控制设计。此外，受BDD约束的设计整合了保证最小衰减率，并定义了一种新的数值指标来量化分散稳定性证书中固有的保守性。通过IEEE 9节点测试系统的案例研究，验证了所提出的带有BDD约束和最小衰减率实现的控制设计。
英文摘要
Integrating inverter-based resources (IBRs) from multiple vendors into power systems is challenging because their controllers are typically designed independently, with little coordination. To address this problem, this paper proposes a decentralized control synthesis framework for IBRs based on block-diagonal dominance (BDD) theory, which ensures the small-signal stability of multi-IBR power systems. By leveraging the grid frequency response, this approach enables a decentralized multi-input multi-output (MIMO) control design. Furthermore, the BDD-constrained design integrates a guaranteed minimum decay rate and defines a novel numerical metric to quantify the conservatism inherent in the decentralized stability certificate. The proposed control design with BDD constraints and minimum decay rate implementation is validated through a case study of the IEEE 9-bus test system.
