Influence of extreme weather and climate change on the resilience of power systems: Impacts and possible mitigation strategies

Situation awareness (SA) has become a widely used construct within the human factors community, the focus of considerable research over the past 25 years. This research has been used to drive the development of advanced information displays, the design of automated systems, information fusion algorithms, and new training approaches for improving SA in individuals and teams. In recent years, a number of papers criticized the Endsley model of SA on various grounds. I review those criticisms here and show them to be based on misunderstandings of the model. I also review several new models of SA, including situated SA, distributed SA, and sensemaking, in light of this discussion and show how they compare to existing models of SA in individuals and teams.

Situation Awareness Misconceptions and Misunderstandings

There are both economic and environmental urges for transition from the current outdated power grid to a sensor-embedded smart grid that monitors system stability, integrates distributed energy and schedules energy consumption for household users. Especially with the proliferation of intelligent measurement devices, exponential growth of data empowers this transition and brings new tools for the development of different applications in power system. Under this context, this paper presents a holistically overview on the state-of-the-art of big data technology in smart grid integration. First, the features of smart grid and the multisource of energy data are discussed. Then, this paper comprehensive summarizes the applications leveraged by big data in smart grid, which also contains some brand new applications with the latest big data technologies. Furthermore, some mainstream platforms and knowledge extraction techniques are looked to promote the big data insights. Finally, challenges and opportunities are pointed out in this paper as well.

This paper describes active research on situation awareness (SA) as it applies to the power transmission and distribution (T&D) industry. Recent emphases on situation awareness in the power T&D industry have highlighted the lack of SA-related research in this domain. This gap has been recognized by several organizations, leading to the development of new commercial energy management systems, reactive reserve monitoring tools, and visualization systems designed to assist T&D operators in monitoring, predicting, anticipating, and preventing potential problems that could lead to major power outages. The essential element in each of these endeavors is a focused effort on understanding and increasing operator SA in T&D control centers. The power T&D domain presents multiple vantage points upon which operator SA can be improved. The power T&D industry continues to seek a solution to its situation awareness gap. The work described in this paper helps to identify areas where SA needs are lacking within the industry, and provides valuable insights to inform the development of future technology to support SA in the power T&D domain.

Situation awareness: State of the art

This paper describes the continued development of a scaled-world simulation designed to conduct empirical research on team cognition and decision-making within a distributed environment. The NeoCITIES simulation was created to study decision-making and the impact of hidden knowledge profiles on team performance within a distributed command, control, and communications (C3) setting. NeoCITIES has been designed for the purpose of representing both new and operationally relevant scaled worlds, while emulating the complexities and attributes of emergent decision-making scenarios involving emergent counterterrorism events. Because patterns of activity emerge across time, knowledge is often hidden and disconnected within and across teams. NeoCIITES has been orchestrated to assess and evaluate the extent to which teams can socially construct knowledge while ineteracting through various means of technological support. Specifically, NeoCITIES is an interactive computer program designed to display information perta...

The Neocities Simulation: Understanding the Design and Experimental Methodology Used to Develop a Team Emergency Management Simulation

This paper describes work on the development of an actionable model of situation awareness for Army infantry platoon leaders using fuzzy cognitive mapping techniques. Developing this model based on the formal representation of the platoon leader provided by the Goal-Directed Task Analysis (GDTA) methodology advances current cognitive models because it provides valuable insight on how to effectively support human cognition within the decision-making process. We describe the modeling design approach and discuss validating the model using the VBS2 simulation environment.

Using fuzzy cognitive mapping techniques to model situation awareness for army infantry platoon leaders

This paper describes a scaled-world simulation developed to conduct empirical research on team cognition, communication, and decision-making within a distributed environment. The NeoCITIES simulation is an advancement of the CITIES task, which was designed to study group decision-making within a command, control, and communications (C3) setting (Wellens & Ergener, 1988). Studying group decision-making is a two-fold problem involving team cognition and team communication. According to McNeese (2003), team cognition is constructed through distributed and emerging activities via several sources. A majority of studies examining distributed decision-making have involved militaristic, battlefield engagement, or urban warfare settings. In that same spirit, NeoCITIES was designed for emergency crisis management teams undergoing terrorist attacks within a college-town. Thus, NeoCITIES is a new and operationally relevant scaled world that emulates the complexities and emergent decision-making attributes resident in...
