论文摘要
在本文中，我们研究了考虑到负载调换器（LTC）动力学的长期电压稳定性的监测和控制。我们表明，在通用条件下，LTC动力学始终承认独特的稳定平衡。对于稳定的平衡，我们表征其吸引区域（ROA）的明确内部近似。与现有结果相比，ROA表征的计算复杂性大大降低。提出了针对ROA表征问题的四次约束线性程序公式。此外，我们制定了一个二阶锥体程序，用于在线电压稳定性监控和控制拟议的ROA表征以及基于ADMM的分布式算法以解决问题。使用标准IEEE测试系统证明了所提出的配方和算法的功效。
In this paper, we study the monitoring and control of long-term voltage stability considering load tap-changer (LTC) dynamics. We show that under generic conditions, the LTC dynamics always admit a unique stable equilibrium. For the stable equilibrium, we characterize an explicit inner approximation of its region of attraction (ROA). Compared to existing results, the computational complexity of the ROA characterization is drastically reduced. A quadratically constrained linear program formulation for the ROA characterization problem is proposed. In addition, we formulate a second-order cone program for online voltage stability monitoring and control exploiting the proposed ROA characterization, along with an ADMM-based distributed algorithm to solve the problem. The efficacy of the proposed formulations and algorithms is demonstrated using a standard IEEE test system.
