Abstract

Co-simulation is an emerging method for cyber-physical energy system (CPES) assessment and validation. Combining simulators of different domains into a joint experiment, co-simulation provides a holistic framework to consider the whole CPES at system level. In this paper, we present a systematic structuration of co-simulation based on a conceptual point of view. A co-simulation framework is then considered in its conceptual, semantic, syntactic, dynamic and technical layers. Coupling methods are investigated and classified according to these layers. This paper would serve as a solid theoretical base for specification of future applications of co-simulation and selection of coupling methods in CPES assessment and validation.

Highlights

Moving towards a decarbonized scenario, the power grid is expecting a high penetration of distributed and renewable energy resources and advanced Information and CommunicationTechnologies (ICT) [1,2], which has a strong impact on the system architecture and is transforming the classical grid into a cyber-physical energy system (CPES)—Smart Grid [3]
Power systems and communication networks, are very different in term of dynamic behavior and hierarchy. The simulation of these systems require different model of computation and solvers [7]
System, researchers have adopted the co-simulation approaches to consider the inter-dependency among domains as well as to validate the system as a whole

Summary

Introduction

Moving towards a decarbonized scenario, the power grid is expecting a high penetration of distributed and renewable energy resources and advanced Information and CommunicationTechnologies (ICT) [1,2], which has a strong impact on the system architecture and is transforming the classical grid into a cyber-physical energy system (CPES)—Smart Grid [3]. On the other hand, emerging issues such as cyber-security requires new tools and methods for assessment. It is, necessary to develop an integrated approach for such complex system in a holistic manner, taking into account the interaction and inter-dependencies among domains [6]. Power systems and communication networks, are very different in term of dynamic behavior and hierarchy. The simulation of these systems require different model of computation and solvers (i.e., a power system is often simulated as continuous system with capability of generating discrete events; ICT system is in general simulated as discrete event simulation) [7]
