Abstract
As the energy management system (EMS) participates in the closed-loop control of shipboard integrated power system (IPS), the information network of EMS is closely coupled with the power system and its characteristics affect power system performance significantly. To study the close-coupling relationship between the two systems, a cyber–physical co-simulation platform based on the high level architecture (HLA) framework is constructed in this paper. The proposed platform uses PSCAD and OPNET to simulate shipboard power system and information network respectively, and utilizes OPNET HLA nodes and PSCAD user-defined modules to implement co-simulation interfaces. In order to achieve a higher co-simulation precision without impairing efficiency, an optimized event-driven co-simulation synchronization method is also proposed. By pre-defining power system synchronization points and detecting information network synchronization points in the co-simulation process, both systems can be synchronized in time and the synchronization error is eliminated. Furthermore, the co-simulation efficiency is also improved by optimizing the data transmission in the synchronization process. A co-simulation model of shipboard power distribution network protection based on CAN bus communication is built and analyzed. Simulation results show that the proposed co-simulation platform and synchronization method are feasible and effective.

Summary
With the wide application of shipboard integrated power system (IPS) in large ships, the management of shipboard electric energy generation, distribution and consumption is increasingly complex. In the field of CPPS co-simulation research, HLA has been widely applied in platforms and researches such as EPOCHS (Electric power and communication synchronizing simulator) [17,18], INSPIRE (Integrated co-simulation of power and ICT systems for real-time evaluation) [19,20,21], wide area network protection research [22,23,24], etc. Electronics 2020, 9, x FOR PEER REVIEW distribution network protection based on CAN bus communication is built in the co-simulation platform Both the platform and the synchronization method are validated by simulation results.
