Abstract: For power cyber-physical system (CPS) formed by integration of traditional power systems and advanced information technology, the coupling between the power system on the physical side and the communication network on the information side are continuously deepened. which leads to increasingly serious power system failures caused by communication problems such as network failures and malicious attacks, and the traditional simulation methods are no longer suitable for simulating and analyzing such scenarios. Based on an analysis of the state of the art in power CPS simulation technology, the embedded control components and penetration testing components are designed with mainstream real-time simulation tools. Based on the multi-component parallel architecture, a real-time co-simulation platform with multiple real-time simulation modes is designed for power CPS, and the overall architecture and component operating mechanism are discussed in detail. At last, the testing cases covering a variety of simulation scenarios are proposed, and the simulation results have verified the effectiveness and accuracy of the platform. This platform can satisfy the real-time simulation requirements of the power CPS for main operating scenarios, and can support the functions of multi-terminal communication and penetration testing.
