随着先进的量测、通信和网络技术的应用,电力系统正逐步演化发展为信息物理电力系统(cyber physical powersystem,CPPS)耦合网络。CPPS的稳定性、安全性分析和控制器校验,均依赖于其动态仿真。文章综述了CPPS仿真领域的相关研究。首先指出CPPS是由连续动态和离散时间耦合的混成系统,并概括其基本特点。随后,围绕CPPS耦合网络的联合仿真问题,从系统建模、平台构建、关键技术和仿真应用4个方面对已有工作进行了回顾和综述,特别关注了如何将连续动态和离散事件系统的仿真模型与框架结合起来,形成统一的联合仿真平台,实现仿真过程中两者的相互配合。在此基础上,分析了实现CPPS耦合网络仿真需要解决的关键问题,即仿真模型的合理简化与高效协调机制的设计,为后续相关研究指明了方向。
With the application of advanced measurement, communication and network technologies, the power system is gradually evolving into a coupled physical network of cyber physical powersystem (CPPS). CPPS stability, safety analysis and controller verification, all rely on its dynamic simulation. The article summarizes the relevant research in the field of CPPS simulation. First of all, CPPS is a mixed system of continuous dynamic and discrete time coupling, and summarizes its basic characteristics. After that, the existing work is reviewed and summarized from four aspects of system modeling, platform construction, key technologies and simulation applications, especially focusing on how to simulate continuous dynamic and discrete event systems Models and frameworks combine to form a unified joint simulation platform to achieve mutual cooperation in the simulation process. On this basis, the key problems that need to be solved to realize CPPS coupled network simulation are analyzed, that is, the reasonable simplification of simulation model and the design of efficient coordination mechanism indicate the direction for the related research.
