Seeing global power system states with compact visualization techniques

The paper outlines the hierarchical approach and the underlying concept of the Compact System State Display (CSSD) as a visualization system with individual displays for managing power systems. The need for an improved man-machine-interface of energy management systems is shown as a result of changes in the field of power supply towards an open market and existing representations are discussed. The paper describes the applied numerical and graphical data compression methods in detail. Finally, some example displays for the global power system operating state and several aspects of the system state are presented.
