The rapid growth of distributed energy resources (DERs) has prompted increasing interest in the monitoring and control of DERs through hybrid smart grid communications resulting in the typical smart grid cyber-physical system. To fully understand the interdependency between them, we propose to integrate the Network Simulator 3 (NS3) into the High Engine for Large-Scale Infrastructure Co-Simulation (HELICS), a new open-source, cyber-physical-energy co-simulation platform. This paper aims to the development and case study of the HELICS-based high performance distribution-communication co-simulation framework for the DER coordination. The novel co-simulation framework for the NS3 integrating into the HELICS is developed. The DER monitoring application about hybrid smart grid communication network design is simulated and validated on this proposed HELICS-based cyber-physical co-simulation platform.

This paper introduces a high-performance computing (HPC) implementation of the large-scale transmission and distribution (T/D) power flow co-simulation. A distinguishing aspect of this implementation is that a commercial grade simu-lator, CYMDIST, is integrated into the co-simulation platform to simulate the distribution power flow. It is believed to be the first effort for incorporating commercial distribution grid simulator in an HPC enabled co-simulation platform. However, the speedup of the presented co-simulation platform has a upper bound, and it is analyzed and formulated in the case study.

Recent trends in aviation have led many general aviation pilots to adopt the use of iPads (or other tablets) in the cockpit. While initially used to display static charts and documents, uses have expanded to include live data such as weather and traffic information that is used to make flight decisions. Because the tablet and any connected devices are not a part of the onboard systems, they are not currently subject to the software reliability standards applied to avionics. In this paper, we create a risk model for electronic threats against mobile cockpit information systems and evaluate three such systems popular with general aviation pilots today: The Appareo Stratus 2 receiver with the ForeFlight app, the Garmin GDL~39 receiver with the Garmin Pilot app, and the SageTech Clarity CL01 with the WingX Pro7 app. We found all three to be vulnerable, allowing an attacker to manipulate information presented to the pilot, which in some scenarios would lead to catastrophic outcomes. Finally, we provide recommendations for securing such systems.
