摘要
信息物理系统(cyber physical system,CPS)是随着工业信息化发展而提出的新理念,强调在生产中物理过程与信息处理的紧密融合。电网正向智能化发展,是典型的信息物理融合系统。建立CPS模型有助于更好分析、控制日益复杂、灵活的电网运行,该文结合电网特点、需求,分析了电网CPS模型的构成和形式,提出了基于混合系统的电网CPS建模方法及其控制方案;并根据上述方法和步骤,建立柔性负荷和源储协调控制的混合系统模型,提出基于该模型的优化控制问题。
The cyber physical system（CPS） is a new concept proposed with development of industry informatization, which focuses on the close fusion of physical and information processing. Power system is a typical CPS system which develops towards intelligence. Modeling this fusion system will contribute to analyzing and controlling the increasing complex and flexible power system operation. Combining the feature and demand of power system, this paper analyzed its CPS model including composition, and researched the CPS model based on hybrid system. Flexible load control and coordinated control of power source and energy storage would be modeled as examples to illustrate the method above, and the optimal control problems were also proposed according to the models.
