    The authors describe how the use of intelligent systems (IS) is an opportunity to add new dimensions to the field of computer applications in power systems. A number of practical power system problems require logic reasoning, heuristic search, perception, and/or the ability to handle uncertainties; IS tools can be part of their solution. The authors describe how AI-related application areas, such ... View full abstract»

    Despite the growing popularity of the World-Wide Web, few traditional publishers have been willing to venture putting their intellectual property online. In part, this has been a result of a misunderstanding of this new publishing medium, and its implications for traditional print (which stems from the modernist fear of undercutting profits). It also stems from a lack of resolution to many of the ... View full abstract»

    A wide-area protection system against long-term voltage collapse was designed, implemented, tested, modified, and commissioned. The system is based on the present SCADA system in southern Sweden, which has been complemented with input signals and equipment to execute action orders from the protection system. Bus voltages from the transmission system, reactive power output from generators connected... View full abstract»

    The authors describe how the Korea Electric Power Corporation (KEPCO) has successfully completed twenty-four overhead transmission line upgrade projects in Korea from 1994 to 1997 for a total cost of US$54.6 million. Upgrades to existing transmission lines were accomplished by replacing existing conductors with high ampacity conductors using existing towers and rights-of-way. Transmission line cap...

    As open transmission access is becoming a reality, a major concern of electric power utilities is to maintain the reliability of the grid. Increased power transfers raise concerns about steady-state overloads, increased risks of voltage collapse and potential stability problems. Strengthening the protection and control strategies is what utilities must do to prevent a local problem from spreading ... View full abstract»
