本文的主要思想是说明各种电力系统运行限制和纠正措施之间的相互作用。重点研究了作为纠偏措施的线流限制与主动再调度之间的相互作用。所提出的方法通过显式地将线流方程包含到系统模型方程集中来处理大范围的流量限制。讨论了主动发电再调度的四种方案。讨论了该方法在解除管制的环境中，由安全协调员或传输提供者在其安全约束下运行电力系统的适用性。该电力系统模型基于一个计算效率高的崩溃潮流点，用于跟踪由于系统参数变化缓慢而导致的稳态行为。利用IEEE-39和IEEE-118总线系统获得的测试结果说明了所提出方法的性能。
The main idea of this paper is to illustrate the interaction between various kinds of power system operational limits and corrective actions. In particular, the paper focuses on the interplay between line flow limits and active generation redispatch as the corrective action. The proposed methodology handles a wide range of flow limits by explicit inclusion of line flow equations into the set of the system model equations. Four options for active generation redispatch are discussed. The applicability of the methodology in deregulated environments for operating a power system within its security constraints by Security Coordinators or Transmission Providers is discussed. The power system model is based on a computationally efficient point of collapse power flow for tracing steady state behavior due to slow system parameter variations. Results of tests obtained with help of the IEEE-39 and IEEE-118 bus systems are given to illustrate the performance of the proposed methodology.
