Along with the deeper coupling between power system and information communication system

such traditional simulation methods as decoupling communication and ideal simulation can hardly satisfy the realistic demand because of the communication faults of time delay

bit error and interruption. Based on an analysis of existing modeling techniques of cyber physical system

a master-slave mode co-simulation platform supported by MATLAB and OPNET is proposed. Some key problems such as the co-simulation framework

the model in MATLAB and OPNET

software-based virtual measuring equipment and interactive interface are expounded

in which a hybrid time synchronization strategy is designed and analyzed. A microgrid case study is given to demonstrate the feasibility and availability of the co-simulation platform. This work is supported by National Natural Science Foundation of China(No. 51677025)
