“…Early models and software for transmission and distribution systems emerged when computers started to become popular for business purposes. Following the rapid development in distributed and parallel computing, distributed power system modeling and analysis has become a widely studied research topic of the last decade [10,30,21,20].…”

Abstract. Electric power grids are presently being integrated with sensors that provide measurements at high rates and resolution. The abundance of sensor measurements, as well as the added complexity of applications trigger a demand for cyber-physical system (CPS) modeling and simulation for evaluating the characteristics of appropriate network fabrics, timing profiles and distributed application workflow of power applications. Although simulation aids in the pre-deployment decision making process, system models for complex CPS can quickly become impractical for the purposes of specialized evaluation of design aspects. Existing modeling techniques are inadequate for capturing the heterogeneous nature of CPS and tend to inherently couple orthogonal design concerns. To address this issue, we present an aspect-oriented modeling and simulation paradigm. The aspectoriented approach provides a separation between functional models and crosscutting modeling concerns such as network topology, latency profiles, security aspects, and quality of service (QoS) requirements. As a case study, we consider a three-area smart grid topology and demonstrate the aspect-oriented approach to modeling network and middleware behavior for a distributed state estimation application. We also explore how aspects leverage scalable co-simulation, fault modeling, and middleware-in-the loop simulation for complex smart grid models.

“…One class of static methodologies identify the cause-andeffect relationships within the cyber-to-physical bridge [26,63,64,81,110] to relate one or more cyber attacks to one more more physical consequences that are further analyzed using power system-specific tools. These techniques can be grouped into a number of classes.…”

“…However, modern power systems are increasingly reliant on sensing, communication, computing and automated control to deliver the efficiency, flexibility and reliability that is required of them. They should therefore be understood as cyberphysical systems (CPSs) [1], where system-level behaviour results from the interplay between physical processes, information flows and control actions. A particular challenge is presented by the fact that power systems are critical infrastructures, where an inability to deliver energy to end users comes at a very high cost.…”

The utilization levels of the transmission network can be enhanced by the use of automated protection schemes that rapidly respond to disturbances. However, such corrective systems may suffer from malfunctions that have the potential to exacerbate the impact of the disturbance. This paper addresses the challenge of jointly optimizing the dispatch of generators and protection settings in this context. This requires a holistic assessment of the cyber (protection logic) and physical (network) systems, considering the failures in each part and their interplay. Special protection schemes are used as a prototypical example of such a system. An iterative optimization method is proposed that relies on power system response simulations in order to perform detailed impact assessments and compare candidate solutions. The candidate solutions are generated on the basis of a security-constrained dispatch that also secures the system against a set of cyber failure modes. A case study is developed for a generation rejection scheme on the IEEE reliability test system (RTS): candidate solutions are produced based on a mixed integer linear programming optimisation model, and loss-of-load costs are computed using a basic cascading outage algorithm. It is shown that the partial security approach is able to identify solutions that provide a good balance of operational costs and loss-of-load risks, both in a fixed dispatch and variable dispatch context.
