The construction of new power system and the Guidelines for power system security and stability in China put forward higher requirements for the efficiency of electromechanical electromagnetic transient hybrid simulation of large power grids. In order to meet the ever-increasing demand for simulation in the future, this paper combines the current development direction of cloud services in the computer field, builds a high-performance computing platform suitable for the characteristics of hybrid simulation computing based on the Internet leading cluster management platform Kubernetes and container virtualization technology, and tests it in Power Dispatch and Control Center of China Southern Power Grid. Through the actual data test, the accuracy of the platform simulation is verified, and the efficiency improvement is basically close to the ideal value provided by the hardware computing power. The simulation time of 60 cases can be reduced to less than 1 hour, which provides a practical computing platform for the simulation analysis of new power system.
