Analysis Methods for Real-Time Control of Dynamically Insecure Power Systems

9526146 Overbye在输电系统上传输电力的能力取决于许多因素，其中最具约束力的是在任何可能的突发事件发生后保持系统完整性的要求。也就是说，如果发生特殊的意外情况，必须有一个可行的计划来将系统恢复到安全的操作点。有了这样的计划，就可以在更高的电力传输水平上运行，因为一旦发生意外，人们就知道如何将系统恢复到安全的工作点；没有这些计划需要更多的约束操作。对于不可解的突发事件，如果在将系统推入不可解状态的突发事件发生后，没有及时采取有效的控制措施，系统将发生动态电压崩溃。该领域的研究将研究不可解性的动态后果，目的是开发计算上可处理的方法，以确定一组最佳控制措施，以恢复这种情况下的安全运行。＊＊＊

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. ***
