Typical Characteristics and Joint Test Verification of Cyber Physical System in Distribution Network

随着多通信方式网络、分布式电源等信息物理资源的加入,传统配电网的信息流和能量流特性发生了重要转变,因此迫切需要从信息物理融合的视角去研究相关运行及控制问题。首先阐述了配电网信息物理系统(cyber physical system,CPS)的5种典型特征;其次,为完整保留能量流和信息流交互过程,从数字与动模测试验证互补的角度,提出配电网CPS数模混合测试验证平台,以支撑该领域理论分析和控制方法研究;最后,基于分布式光伏无功优化控制算例验证了平台的有效性。

With the access of cyber physical resources such as multi-mode communication network and distributed generations,the characteristics of information flow and power flowin the distribution network have gone through an important shift. Therefore,there＇s an urgent requirement to research on the system operation and control issues from the perspective of cyber physical integration. Firstly,this paper specifically analyzes five typical characteristics of cyber physical system（ CPS） in the distribution network. Furthermore,from the perspective of complementation between digital and analog verification,this paper proposes a CPS digital-analog test verification platform of distribution network to support the theory analysis and method research of CPS field,which can hold the complete interaction process between power flow and information flow. Finally,this paper presents a case of reactive power optimization strategy in the photovoltaic（ PV） station to verify the effectiveness of the proposed platform.
