摘要
信息物理融合系统现已广泛应用于交通、医疗等方面。信息物理融合系统集成了计算进程和物理进程,可以利用混合系统对信息物理融合系统建模。大量的分布式能源接入电网中,传感、通信、控制等构成了电力系统的二次系统,.电力系统从简单的能量传输,进化到能量传输与信息流传递并行的现代电网运行体系。电网的物理进程和信息元素的动态关联是连续和离散行为的交互,即混合系统。本文利用混合模型对风机和光伏电池进行信息物理融合建模。
Cyber-physical system( CPS) has been widely applied in transportation,health care and so on. Cyberphysical system,with the integration of physical processes and computing processes,can be modeled using hybrid system. A large amount of distributed energy resources are connected to the grid. Meanwhile,sensing,communication and control construct the secondary power system. Power system evolves from simple energy transmission to the parallel flow of energy transmission and information flow. The joint dynamics of physical processes and cyber elements in power grid are typical of a mixture of continuous and discrete behaviors,namely,hybrid system. In this paper,the cyber-physical models of wind turbin and photovoltaic cell are built with hybrid system.
