U.S.-Korea Cooperative Research on New Technique for Optimization of Long-Term Power System Expansion Planning

本提案要求资助宾夕法尼亚州立大学电气工程系的Kwang Yun Lee博士与韩国首尔国立大学电气工程系教授Young Moon Park博士进行为期24个月的研究项目，研究一种优化长期电力系统扩展规划的新技术。这些合作者将努力确定电力系统在长期规划范围内（通常为5至30年）最经济、最可靠的发电和扩展计划，但要受到一些技术、经济和社会限制。他们将应用庞特拉金的最大原理，并使用关于几种类型发电厂的随机负荷和特性的新假设，以及关于输电网络的其他假设，以简化问题，并有可能开发封闭形式的分析生产模型和可靠性指数，而不是模拟模型。在不牺牲可靠性的情况下，大大减少了计算时间。无论是对电力事业迅速发展的韩国，还是对美国来说，最佳发电和输电都是最重要的课题。在美国，对新电厂需求的预测往往是过度的，正在建设的电厂被取消，造成了巨大的资本损失。该项目旨在开发一种对美国和韩国都有利的电力系统规划新方法。该项目与美韩合作科学项目的目标相关，该项目旨在通过科学信息、思想、技能和技术的交流以及在互利问题上的合作，提高美韩科学家和工程师之间的合作水平。美国和韩国的合作者不仅在课题领域拥有丰富的研究经验和成果发表记录，而且在过去的合作中还共同发表了多篇论文，是备受尊敬的科学家。

This proposal requests funds to permit Dr. Kwang Yun Lee, Electrical Engineering Department, Pennsylvania State University, to pursue with Dr. Young Moon Park, Professor of Electrical Engineering, Seoul National University, Seoul, Korea, for a period of 24 months a program of research on a new technique for optimization of long-term power system expansion planning. These collaborators will attempt to determine the most economical and reliable generation and expansion plan in an electric power system over a long-range planning horizon (usually 5 to 30 years) subject to a number of technical, economical, and social constraints. They will apply Pontriagin's maximum principle and use novel assumptions regarding random load and characteristics of generating plants of several types and other assumptions regarding the transmission network in order to simplify the problem and make it possible to develop a closed-form analytical production model and reliability indices rather than simulation models, with a considerable reduction in computation time, without sacrificing reliability. The topics of optimal electric power generation and transmission are most important both to countries such as Korea, where the utilities are expected to expand rapidly, and to the United States. Predictions about the need for new power plants in the United States often have been excessive and plants under construction have been cancelled with an enormous capital loss. This project seeks to develop a new method for power system planning which would be beneficial to the United States and Korea. This project is relevant to the objectives of the U.S.-Korea Cooperative Science Program which seeks to increase the level of cooperation between U.S. and Korean scientists and engineers through the exchange of scientific information, ideas, skills, and techniques and through collaboration on problems of mutual benefit. The U.S. and Korean collaborators are highly respected scientists who not only have extensive research experience and productive publication records in the field of the proposal but also have produced several joint publications from past collaboration.
