“…According to a field study conducted by Obradovich [15], the operators in the transmission control center are responsible for not only controlling voltage but also coordinating personnel, responding to emergencies, setting and assuring the power flow schedule, etc. They intervene as necessary to regulate power grids and maintain system stability when automation does not function as required or expected.…”

The human operator is an integral part of a stable and safe power system. While there is increasing attention paid to automation improvements, the importance of understanding and training human operators may be understated. This paper discusses a project to enhance operator training programs by evaluating human performance relative to a reference operator model identified using optimal control theory. Along with establishing a simple computer-based operator workstation for future training purpose, this paper describes the optimal control response design methodology for a human-in-the-loop power system experiment. The overall system model is presented. An optimal controller synthesis methodology is applied to the model system and the optimal controller is designed. The performance of the optimal controller is then compared to human subject performance.

“…Regulatory organizations such as the North American Electric Reliability Corporation (NERC) have since mandated data sharing and wide-area views (NERC, 2006) so that operators can detect and respond to incidents in other jurisdictions. The recent increase in intermittent renewable generation (Obradovich, 2011), market deregulation (Sanderson, Memisevic, & Wong, 2004), and cybersecurity risks (Ten, Liu, & Manimaran, 2008) have increased power grid operations' complexity and thus information processing required of operators and EMSs.…”

Operators need new visualizations to help them monitor increasingly complex power grids at wider geographical scopes. We developed a work domain analysis of power grid operations from interviews, focus groups, and observations. The work domain analysis helped determine information requirements for a wide-area monitoring design concept that follows ecological interface design principles. We validated the design concept in a usability evaluation, achieving an above-benchmark System Usability Scale score of 77 out of 90. This work domain analysis and ecological interface design process will equally apply to the design of other power grid monitoring displays.
