“…Although this result supported several previous findings that there is no correlation between workload and situation awareness, the existence of such a correlation is still disputable. Hallbert (1997) has pointed out an interesting point regarding the correlation between workload and situation awareness. He found that a sudden change of workload could cause a decrease of SA, however operators could later regain their SA while the workload remains high.…”

“…In power systems, the size and complexity of the grid poses its own unique challenges. While during normal conditions, operators may show relatively high situational awareness, their awareness level drops following disturbance onset [8], which is when responsiveness and effective decision making is needed most. This has been attributed to elements such as attention narrowing, memory trap, workload fatigue, misplaced visual features, data overload and complexity creep [9].…”

Today's more reliable communication technology, together with the availability of higher computational power, have paved the way for introduction of more advanced automation systems based on distributed intelligence and multi-agent technology. However, abundance of data, while making these systems more powerful, can at the same time act as their biggest vulnerability. In a web of interconnected devices and components functioning within an automation framework, potential impact of malfunction in a single device, either through internal failure or external damage/intrusion, may lead to detrimental side-effects spread across the whole underlying system. The potentially large number of devices, along with their inherent interrelations and interdependencies, may hinder the ability of human operators to interpret events, identify their scope of impact and take remedial actions if necessary. Through utilization of the concepts of graph-theoretic fuzzy cognitive maps (FCM) and expert systems, this paper puts forth a solution that is able to reveal weak links and vulnerabilities of an automation system, should it become exposed to partial internal failure or external damage. A case study has been performed on the IEEE 34-bus test distribution system to show the efficiency of the proposed scheme.
