（N-1）-安全性约束着电网的允许状态，是影响输电网运行和电网规划的决定性因素。在存在不确定性的情况下，确保（N-1）安全的操作和规划是一个特别的挑战。由于限制网络运行的低效率可以通过快速纠正措施来缓解，例如通过FACTS设备，HVDC或移相变压器：纠正（N-1）安全分析考虑了对事故后情况的快速反应。在本文中，首先将提出一种技术经济分析方法，该方法允许对系统运行中的纠正控制进行评估。其次，提出了一种实物期权分析方法来确定不确定情况下输电系统规划过程中纠偏控制所获得的柔性值。最后，将这两种方法应用于欧洲输电系统中移相变压器校正潮流控制的案例研究。
(N-1)-security is a decisive impact factor on both transmission system operation and network planning as it constrains the permissible states of the grid. Ensuring an (N-1)-secure operation and planning is a particular challenge in the presence of uncertainties. The inefficiency due to constrained network operation can be alleviated by fast corrective actions, e.g. by FACTS devices, HVDC or phase shifting transformers: a corrective (N-1)-security analysis accounts for fast reactions to post-contingency situations. In this paper, first an approach for a techno-economic analysis will be presented that allows for the evaluation of corrective controls in system operation. Second, a real options analysis is proposed to determine the value of the flexibility gained by corrective controls in the course of transmission system planning under uncertainties. Finally, the two methods will be applied in a case study for corrective power flow control by phase shifting transformers in the European transmission system.
