Panel Sessions GM 2004 (Denver)

Multi-Agent Systems (MAS) in Power Engineering (panel)

Chair: S. McArthur, University of Strathclyde

Power system operation, control and monitoring are challenging problems due to the complexity of the systems involved and the increasing volumes of data generated. Within the modern utility environment, engineers require improved support in these areas through increased automation and enhanced decision support environments. Multi-agent systems (MAS) technology offers a platform for building the appropriate automated and enhanced decision support functions. A multi-agent system is comprised of independent and autonomous software modules that are able to problem solve while cooperating and negotiating with one another. This panel session will describe the use of multi-agent systems for a range of practical applications including maintenance scheduling, vulnerability assessment, condition monitoring, power system control and post fault analysis. Through these applications, the opportunities and benefits that arise from MAS technology will be clarified. Furthermore, the fundamentals of agent design, agent negotiation, autonomous behavior and agent architectures will be explained.

Systems Applications in Substations (panel)

Chair: M. Kezunovic, Texas A&M University

This panel discusses application of intelligent techniques in implementing local substation functions such as signal sensing, monitoring, control and fault analysis. The techniques that are the focus of the panel include advanced signal processing, expert systems, neural networks, fuzzy logic, genetic algorithms, nonlinear observers, etc. The applications of interest include: fault detection and classification, fault location, analysis of fault clearing, analysis of non-operational data, self-diagnostics, power quality detection and classification, etc. As an underlying consideration, the IEC Standard 61850 that relates to substation automation and communication is also discussed. It is argued that this standard is a prerequisite for a wide application of intelligent techniques in substations. For each of the applications, a variety of benefits from using intelligent techniques are outlined. Future trends are also mentioned.

Component Models and Advanced Tools for Distribution Systems Analysis (panel)

Chair: S. Carneiro, Federal University of Rio de Janeiro

Deregulation of the power industry is an ongoing process in an increasing number of countries. This process has required the development of new tools, to assist engineers and managers with the challenges involved in the planning and operation of power systems. At the distribution level, analytical methods previously designed for HV and EHV transmission systems, have been extended and/or adapted to distribution systems, as well as new modeling techniques and procedures have been designed specifically for distribution systems applications. This session is intended to bring together experts who are dealing with several aspects of distribution systems challenges, ranging from reviews of modeling techniques to fault analysis, among others.

Intelligent Systems for Power System Expansion Planning (panel)

Chair: D. Niebur, Drexel University

With most recent U.S. East Coast power blackouts as well as blackouts experienced in other foreign countries and U.S. states including Italy, Brazil, UK, California and Nevada, the demand for additional power generation as well as enhanced reliability and congestion management for the transmission and distribution grid has come to the forefront. This panel will focus on power system expansion planning in the areas of generation expansion planning, distribution system expansion planning including DG allocation and substation planning. It will join a group of experts from academia and industry to discuss the current planning efforts to ensure adequate grid reliability, role of new computing tools for power system expansion planning and their impact on future power system operation.

Power Sector Reforms and Restructuring in Developing Countries (panel)

Chair: S. A. Khaparde, IIT-Bombay

Power sector reforms in Developing Countries are in a state of flux. The Developing Countries face problems of a different nature than developed countries. This session deals with state of art and real life problems and ways to overcome them in Developing Countries like India, South Korea and Hong Kong. The typical issues include adequacy of transmission system, decentralized control, excessive losses, tariff rationalization, large frequency variations etc. “The Indian Medicine” reports frequency linked tariff, or Availability Based Tariff (ABT) and its success story in real life implementation. With Electricity Act 2003 coming into force in India, its impact on reforms is discussed. The participation of private utilities and issues of distribution sector are also addressed. The analysis of current blackouts in Western Regional Grid in India is presented.
