9526146 Overbye The ability to transfer power on a transmission system is dependent upon a number of factors, with arguably the most constraining being the requirement to maintain system integrity following the occurrence of any of a plausible set of contingencies. That is, if a particular contingency should occur, there must be a viable plan to return the system to a secure operating point. Having such a plan permits basecase operation at higher levels of power transfer since should the contingency occur, one knows how to restore the system to a secure operating point; not having these plans requires more constrained operation. For an unsolvable contingent case, if effective control action is not taken quickly enough following the contingency that pushed the system into the unsolvable state, the system will experience a dynamic voltage collapse. Research in this area will investigate the dynamic consequences of unsolvability, with the aim of developing computationally tractable methods for determining an optimal set of controls to restore such a case to secure operation. ***

小行星9526146 在输电系统上传输电力的能力取决于许多因素，其中最具约束力的可能是在发生任何一组可能的意外事件后保持系统完整性的要求。 也就是说，如果发生特定的意外事故，必须有一个可行的计划，使系统返回到安全的操作点。 具有这样的计划允许在更高水平的功率传输下的基本操作，因为如果发生意外事件，人们知道如何将系统恢复到安全操作点;没有这些计划需要更多的约束操作。 对于不可解的偶然情况，如果在将系统推入不可解状态的偶然事件之后没有足够快地采取有效的控制动作，则系统将经历动态电压崩溃。 在这一领域的研究将调查的动态后果的不可解性，与发展计算上易于处理的方法来确定一套最佳的控制，以恢复这样的情况下，以安全运行的目的。 ***
