摘要
能源互联网系统对物理与信息的协同调控技术要求不断提高,信息物理融合系统可以很好地解决此类问题。在微能源网和信息物理系统的基础上,提出了一种微能源网信息物理系统的基本构架。在物理层面,建立了能源网络模型和能源耦合模型。在信息层面,将电力系统的统一信息模型扩展到能源领域,建立起信息系统模型。对有时滞的微能源网信息物理系统,使用一致性理论对其协调控制,并进行了仿真验证。仿真结果证明了信息时滞对物理系统运行的影响以及一致性理论对系统协调控制的有效性。
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.
