SGER: Hierarchical Power Systems Control in a Changing Industry

9634255 Ilic美国和世界上许多其他地区的电力系统正在经历剧烈的改组。目前的趋势是放松对传统上受到监管的垄断行业的管制，以允许经济竞争。在讨论支持两个极端产业结构的技术和经济概念时，会产生许多混淆。在一个极端，一些人主张保留和建立现有的技术框架和标准，以运行一个相互连接的系统，同时容纳竞争性的非公用事业拥有的发电。另一个极端是那些认为电力系统应该完全基于经济竞争进行重组的人。工程界和经济界都需要改变思路，将辩论置于一个有意义的框架中，这对于确保无论哪种产业结构占上风，都能满足技术操作和自由市场经济的基本原则至关重要。这对于研究大型动态电力系统的研究人员来说是一项艰巨的任务。这些问题的基本性质是系统理论。的确，在大系统方面有强大背景的研究人员可以在与电力工业直接相关的现有问题的背景下发现许多新的理论问题及其解决方案。但是，为了避免可能不适用于所有情况的技术假设，我们需要一个提出这些问题的系统框架。在这个项目中，我们将使用我们所获得的知识作为起点，进一步研究在不断变化的电力行业中的分层控制问题。在接下来的内容中，我们描述了在不断变化的行业中设想的控制结构的重要性，并提出了将要研究的几个具体问题。＊＊＊

9634255 Ilic Electric power systems in the United States and many other parts of the world are undergoing drastic restructuring. The trend is toward deregulating an industry that has traditionally been a regulated monopoly to allow for economic competition. Much confusion arises in discussing technical and economic concepts supporting the two extremes of industry structure. At one extreme, some advocate preserving and building upon the present technical framework and standards for operating an interconnected system while yet accommodating competitive non-utility-owned generation. At the other extreme are those who believe electric power systems should be restructured based entirely on economic competition. A change of thinking is needed in both engineering and economic circles to put the debate in a meaningful framework, which is essential for ensuring that, whichever industry structure prevails, basic principles of technical operation as well as the free market economy are met. This is a tall order for researchers concerned with large dynamic electric power systems. The issues are system-theoretic in their basic nature. True, researchers with a strong back-ground in large systems could identify many new theoretical issues and their solutions within the context of existing problems directly relevant to the power industry. But in order to avoid technical assumptions that may not hold in all cases, one needs a systematic framework for posing these problems. In this project, we will use much of our acquired knowledge as the starting point to further study the problems of hierarchical controls in a changing electric power industry. In what follows, we describe the importance of the envisioned control structures in a changing industry, and propose several specific problems that will be studied. ***
