论文摘要
电力系统中的传输线失败非局部传播和级联。在这项工作中，我们提出了一种自适应控制策略，在缓解和定位线路故障方面提供了强有力的保证。具体而言，我们利用网络桥梁分解的属性和称为统一控制的频率调节方法。如果统一控制的平衡区域与网络的桥梁块相吻合，则提议的策略将后宿主系统驱动到稳定状态，在这种状态下，在可能的情况下，在可能的情况下，初始线路停电的影响位于可能的区域内，从而阻止了级联过程。当无法本地使用初始线路时，提出的控制策略提供了可配置的设计，该设计逐渐涉及并协调更多平衡区域。我们将所提出的控制策略与IEEE 118-BUS和2736-BUS测试网络上的经典自动生成控制（AGC）进行了比较。仿真结果表明，我们的策略可以大大提高N-K安全标准的总体可靠性，并将初始失败的影响定位在大多数模拟意外情况下。此外，与AGC相比，在我们所有的案例研究中，所提出的框架将显着减少负载损失（如果有的话）。
Transmission line failures in power systems propagate and cascade non-locally. In this work, we propose an adaptive control strategy that offers strong guarantees in both the mitigation and localization of line failures. Specifically, we leverage the properties of network bridge-block decomposition and a frequency regulation method called the unified control. If the balancing areas over which the unified control operates coincide with the bridge-blocks of the network, the proposed strategy drives the post-contingency system to a steady state where the impact of initial line outages is localized within the areas where they occurred whenever possible, stopping the cascading process. When the initial line outages cannot be localized, the proposed control strategy provides a configurable design that progressively involves and coordinates more balancing areas. We compare the proposed control strategy with the classical Automatic Generation Control (AGC) on the IEEE 118-bus and 2736-bus test networks. Simulation results show that our strategy greatly improves overall reliability in terms of the N-k security standard, and localizes the impact of initial failures in the majority of the simulated contingencies. Moreover, the proposed framework incurs significantly less load loss, if any, compared to AGC, in all our case studies.
