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

电力系统在现在和未来的有效运行在很大程度上取决于今天如何应对一些新出现的挑战。电力系统继续承受压力，因为它们在许多情况下是满负荷或接近满负荷运行的。增加新的输电线路来缓解这种压力通常非常困难，并且陷入监管程序的困境。随着越来越多的电力从更远的地方运输，新的放松管制的环境有可能加剧这种压力。与此同时，新的柔性交流输电系统（FACTS）设备正在不同地点进行调试。虽然这些设备可以提供显著的性能改进，并可能有助于缓解所提到的一些问题；它们确实具有独特的动态特性，与现有设备相比不太熟悉。此外，FACTS控制系统的合理设计和分析对于高效运行至关重要。合并这些FACTS装置的整个系统的最终动态行为尚未得到很好的理解。因此，这些设备的潜在好处可能没有完全实现。未来的市场机制将关系到经营条件和交易合同的建立。由于市场将面向充分利用高效发电，因此将对某些地区的输电网施加额外的压力。为满足日益增长的需求，分布式发电的新技术正在迅速引入系统。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。这些重要的问题需要在实时控制、传感、通信、经济、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。选定的参与者将发表立场文件，并就关键研究问题进行讨论。研讨会将聚焦于辨识电力系统中可能受益于系统与控制理论发展的新问题，并呈现大型网路的控制、运作与经济方面的新研究思路，以及它们在电力系统中的应用。报告和讨论的结果将作为确定未来在大型电力系统领域的研究需要和满足这些需要的方法的基础。报告、讨论和对未来研究的建议将在研讨会论文集中发表。

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.
