This award is made under the Exploratory Research on Engineering the Transport Industries (ETD program solicitation.With the emerging restructured nature of the power industry, there is a need to look at new approaches to modeling as well as tools of analysis. Among the transport industries, the power industry can both profit from the experience of other deregulated industries, as well as offer new ideas in terms of modeling and analysis.Increasingly, discrete events affect the performance of systems in real time. Such events are common in the physical system, for example relays, tap changing transformers, and FACTS devices. However the rules underlying the market layer also introduce discrete events. System performance under these conditions, where continuous dynamics and discrete events interact, is the principal focus of the proposal,A major theme is to map formal languages that describe hybrid systems, such as Petri nets and finite state automata, into a differential-algebraic model structure. A linking strategy will be exploited to maximize model flexibility. We shall also focus on trajectory sensitivity analysis of hybrid systems. Application areas that build upon trajectory sensitivities will be investigated. Trajectory sensitivity analysis entails a heavy computational burden. Hence new numerical analysis approaches such as iterative solver techniques will be considered. Finally the interaction of the market layer with the physical system will be explored,The results of the research will be in the form of formulating new areas of research for the restructured power industry.

该奖项是在交通运输行业工程探索性研究（ETD）项目征集下颁发的。随着电力行业不断出现的重组性质，有必要研究新的建模方法和分析工具。在运输行业中，电力行业既可以从其他放松管制的行业的经验中获益，也可以在建模和分析方面提供新的思路。离散事件越来越多地影响系统的真实的性能。此类事件在物理系统中很常见，例如继电器、分接变压器和FACTS设备。然而，作为市场层基础的规则也引入了离散事件。在这些条件下，连续动态和离散事件相互作用的系统性能，是该提案的主要焦点，一个主要的主题是映射形式语言，描述混合系统，如Petri网和有限状态自动机，到微分代数模型结构。将采用一种连接战略，以最大限度地提高模型的灵活性。我们还将集中在混合动力系统的轨迹灵敏度分析。将研究建立在轨迹敏感性基础上的应用领域。轨迹灵敏度分析需要很大的计算负担。因此，将考虑新的数值分析方法，例如迭代求解器技术。最后探讨市场层与物理系统的互动关系，研究结果将为电力工业重组提供新的研究领域。
