A description is given of a human factors analysis carried out on the man-machine interface (MMI) needs of energy management systems (EMSs), with focus on the applications of full-graphics display technology for these systems. The need for and purpose of human-factors analysis are discussed. Conclusions are presented regarding switching operations, screen management, automatic generation control, unit commitment, and security analysis. The results of the study demonstrate that advanced features such as world map, pan, zoom, and declutter applied to SCADA, network diagrams, and tabular applications displays enhance operator effectiveness. While some examples are drawn from an actual implementation, this is not a description of a specific MMI or a design description
