Abstract:The requirements of physical and informational coordinated control technology for the energy internet system are constantly improved. Cyber Physical System (CPS) can well solve the problem. Based on previous studies of micro-energy network and CPS, a basic framework of CPS for micro-energy network is presented in this paper. Models of energy network and energy coupling are established at the physical level. Common information model of power system is extended to the energy field and the model of information system is established at the information level. The consensus theory is used to control CPS for micro-energy network which has response delay, and the simulation is done to validate its effectiveness. The simulation results show that the information delay has an effect on the physical system operation, and also prove the validity of the consensus theory on system coordination control.
