Power management system/energy control center design

Many factors must be considered in order to design a power management system (PMS) which is effective from both a cost and benefit point of view. This paper reports on a conceptual design study and the initiation of a development project to enhance the capability of a PMS for a major electric power system. Insights are provided relative to the determination of true PMS requirements, the assessment of alternative design strategies, and the planning of a phased system development.A brief historical background of the use of computers in power system operations is given, and the justification of a PMS concept is discussed in terms of costs incurred and performance and values returned. The relationship between growth trends, technological advances, and the functional or applications requirements of a PMS are presented. Simulation studies and investigative analyses which are essential to the evaluation and selection of alternatives are cited and positioned in an overall system development life cycle.
