The generation mix of ISO New England is fundamentally changing. The representation of nuclear, coal and oil generation facilities is set to dramatically fall, and natural gas, wind and solar facilities will come to fill their place. Solar and wind introduce greater uncertainty and must be accurately forecasted. This paper introduces the findings of a study launched by ISO New England on 12 predefined scenarios, six for 2025 and six for 2030, with varying penetration of variable energy resources (VERs) as well as dispatchable generation. The heart of the study's methodology is a novel, but now extensively published, holistic assessment approach called the Electric Power Enterprise Control System (EPECS) simulator. The EPECS methodology has been published and validated by ISO New England. The findings of this study highlight the need for more holistic assessment of operational techniques such as in the determination of operating reserves and curtailment. For cases with high penetration of VERs (2025–3, 2030–2, 2030–3 and 2030–6) the study shows the system's inability to mitigate imbalances due to inadequate load-following, ramping and regulation reserves. The potential for congestion on the interfaces is also observed for these scenarios. In addition to these issues, the study highlights the integral role of curtailment in dealing with negative net load in the presence of “must-run” generation.

The need for cybersecurity knowledge and skills is constantly growing as our lives become more integrated with the digital world. In order to meet this demand, educational institutions must continue to innovate within the field of cybersecurity education and make this educational process as effective and efficient as possible. We seek to accomplish this goal by taking an existing cybersecurity educational technology and adding automated grading and assessment functionality to it. This will reduce costs and maximize scalability by reducing or even eliminating the need for human graders.

Many species of fish school, or swarm, to increase their chances of survival in the wild. For this, they rely on their ability to sense the environment around using a multitude of sensory inputs. In robotics, researches have often tried to mimic both the fish's ability to swarm but also their ability to perceive their environment. In this paper, the effects of different sensor characteristics are coupled with simple swarming rules to determine what a robotic fish would require to be able to interact with other agents in a swarm. The purpose is the further development of a bio-inspired robotic fish designed to interact, and one-day monitor, a school of fish. Due to time, cost and the repeatability to test the design and swarming rules with real fish, the design and development of the robotic fish is being undertaken in a virtual environment. Simulating the robotic fish also allows the parameters such as the type of sensor used to be easily and quickly changed. It also has the additional benefit of being able to use Virtual Reality, which makes modifying and interacting with the simulation easier. This paper demonstrates what effect the different sensor types will have on a robotic fish's ability to swarm with real fish.

At the pre-concept stage, an architect explores the problem space together with various stakeholders, including engineers, marketing, and future users of the system. This requires competencies and tactics to communicate efficiently while maintaining a system-level scope. We present a practical Structured Problem Exploration approach to assist architects in exploring the problem space. The approach aims to ensure that involved parties are talking on the same level. The approach includes a checklist to elicit information relevant to the system-level scope and activities to warrant convergence of the results. This paper starts with an overview of soft competencies, skills, and methods. After outlining the approach, we report our experiences with applying it to investigate energy improvement opportunities of a connected system. This paper aims to inform discussions on the importance of competencies and methods for the pre-concept exploration stage when creating SoS elements.

This paper presents the design of Hector- Vr®, a mixed-reality driving simulator specially developed for older drivers. Hector- VR®uses a physical vehicle combined with an Oculus Rift virtual-reality head mounted display to provide an immersive driving experience and test a user's driving performance and competence. The mixed-reality driving simulator System of Systems design, which consists of sensor and actuator systems, user-interface systems, and data-storage-and-reporting systems, can be integrated as a service within an aged-care facility. Results show positive responses from user evaluations conducted over three development phases (alpha, beta, and final), indicating a high level of agreement among users in terms of ease-of-use.
