International workshop on control and power systems, Washington, DC, between November and December 2000

当前和未来电力系统的有效运行在很大程度上取决于今天如何很好地应对几个新出现的挑战。电力系统继续受到压力，因为它们在许多情况下以满负荷或接近满负荷运行。增加新的传输线以缓解这种压力通常是非常困难的，并深陷监管程序的泥潭。随着更多的电力从更远的距离输送，新的放松管制的环境可能会加剧这种压力。与此同时，新的灵活交流输电系统(FACTS)设备正在各地投入使用。虽然这些设备可以提供显著的性能改进，并可能帮助缓解所提到的一些问题，但它们确实具有与现有设备相比不太熟悉的独特的动态属性。此外，对FACTS的控制系统进行适当的设计和分析是有效运行的关键。由此产生的合并了这些FACTS设备的整个系统的动态行为并没有得到很好的理解。因此，这些设备的潜在好处可能没有完全实现。未来的市场机制将对经营条件和已建立的交易合同产生影响。由于市场将充分利用高效发电，因此在某些地点的输电电网将受到额外的压力。涉及分布式发电的新技术正迅速引入该系统，以满足日益增长的需求。因此，需要解决与系统互连、可靠性和位置相关的几个重要技术问题。这些重要问题需要在实时控制、传感、通信、经济学、建模和大规模系统分析等领域开展工作。我们建议举办一次研讨会，将上述领域的研究人员、科学家和联邦机构参与者聚集在一起。选定的参与者将提交立场文件，并将进行涉及关键研究问题的讨论。研讨会将集中于确定电力系统中新出现的问题，这些问题可以从系统和控制理论的发展中受益，并介绍在大型网络的控制、运行和经济及其在电力系统中的应用方面的新研究思路。专题介绍和讨论的结果将作为确定未来在大规模电力系统领域的研究需要以及满足这种需要的手段的基础。对未来研究的陈述、讨论和建议将发表在研讨会会议记录中。

The effective operation of power systems in the present and the future depends to a large extent on how well several emerging challenges are met today. Power systems continue to be stressed as they are operated in many instances at or near their full capacities. Addition of new transmission lines to relieve this stress is often very difficult and is mired in regulatory procedure. The new deregulated environment has the potential of exacerbating this stress as more power is shipped from longer distances. At the same time, new flexible ac transmission system (FACTS) devices are being commissioned in various locations. While these devices can offer significant performance improvements and may help alleviate some of the problems alluded to; they do have unique dynamic properties that are less familiar than those of existing devices. In addition proper design and analysis of control systems for FACTS is crucial for efficient operation. The resulting dynamic behavior of the overall system that incorporates these FACTS devices is not well understood. Consequently, the potential benefits of these devices may not be fully realized. The market mechanisms in the future will have a bearing on the operating conditions and the transaction contracts that are established. Since the market would be geared to fully utilizing efficient generation, additional stress would be imposed on the transmission grid in certain locations. New technology involving distributed generation is being rapidly introduced in the system to meet growing demand. As a result several important technical issues related to system interconnection, reliability, and location need to be addressed. These important issues call for work in the areas of real time control, sensing, communication, economics, modeling, and analysis of large scale systems.We propose to conduct a workshop that will bring together researchers, scientist, and federal agency participants in the areas described above. Selected participants will present position papers and discussions that address key research issues will be conducted. The workshop will focus on identifying emerging problem in power systems that can benefit from the system and control theoretic developments as well as presenting new research ideas in the control, operation, and economics of large networks and their application to power systems. The outcomes of the presentations and discussions will be used as the basis to identify future research needs in the area of large-scale power systems and the means by which such needs can be met. The presentations, discussions, and recommendations for future research will be published in the workshop proceedings.
