Cyber Physical Power Systems: Architecture,Implementation Techniques and Challenges

引入前沿信息技术并把电力系统和信息系统进行深度融合是实现电力系统智能化的关键。信息物理融合系统(cyber physical system,CPS)是通过3C(computation,communication,control)技术将计算、网络和物理环境融为一体的多维复杂系统,通过多技术有机融合,实现大型工程系统的实时感知、动态控制和信息服务,具有非常广阔的应用前景,因而在国际上受到了普遍重视。在此背景下,基于CPS概念并结合电力系统特点,提出建立电力CPS的思路和框架。首先,概述了CPS的概念、主要功能和技术特征。之后,构造了电力CPS的架构和主要组成部分,指出了实现电力CPS的若干关键技术。最后,从基础理论、建模方法、仿真算法、安全性分析、可靠性分析、系统设计与规划、运行调度、标准化等方面讨论了电力CPS研究中所面对的主要挑战。

To implement the objective of smart grids,it is essential to introduce the state of the art computing,communication and sensing technologies,and seamlessly integrate them with the power system.The cyber physical system（CPS） is an emerging but highly important research area concerning the deep integration of physical and information systems.In this work,based on the concept of the CPS and taking into account the characteristics of power systems,the cyber physical power system（CPPS） is proposed.The concept,main functionalities and technical characteristics of the CPS are first introduced.The architecture and major components of the CPPS are then illustrated.Next,some important techniques for developing the CPPS are clarified.Finally,several important research problems associated with the CPPS,including the theoretical foundation,system modelling,simulation algorithms,security assessment,reliability assessment,system design and planning as well as system operation,and the standardization of CPPS,are presented.
