A Hybrid Approach to Transport Industry Modeling: A Power System Viewpoint

该奖项是在交通运输行业工程探索性研究(ETD计划征集)下颁发的。随着电力行业的新兴重组性质，需要研究新的建模方法和分析工具。在交通运输行业中，电力行业既可以借鉴其他放松管制行业的经验，又可以在建模和分析方面提供新的思路，离散事件对系统性能的影响越来越大。这类事件在物理系统中很常见，例如继电器、分接变换变压器和FACTS装置。然而，市场层面的规则也引入了离散事件。在连续动态和离散事件相互作用的这些条件下的系统性能是建议的主要焦点，一个主要主题是将描述混合系统的形式语言，如Petri网和有限状态自动机，映射到微分-代数模型结构。将利用链接战略来最大限度地提高模型的灵活性。我们还将重点研究混杂系统的轨迹灵敏度分析。将调查建立在弹道敏感性基础上的应用领域。弹道灵敏度分析的计算量很大。因此，将考虑新的数值分析方法，如迭代求解器技术。最后将探讨市场层与物理系统的相互作用，研究结果将以制定新的电力行业重组研究领域的形式出现。

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.
