Study On Modeling Platform Of Cyber-Physical Energy System

Cyber-physical systems (CPS) refer to the physical systems, which aremonitored, coordinated, controlled and compactly integrated by thecomputing and communication networks. The cooperation of CPS andpower system certainly become as the base in development of smart grid.This paper introduces the method integrating respectively existing cyberand physical model to form one CP model. Afterwards, based on single CPmodel establishment, it presents the method to combine multiple CPmodels to organize one integrated CP model or even CP system.Applied the proposed CP modeling method on photovoltaic (PV), energystorage battery and the coordination control of them, this paper achievestheir specific CP models respectively. With construction the dynamicphysical model and static cyber model of each, we propose themonogamously corresponding analysis between each physical and cybermodel, with achievement the integration of CP on model level.The simulation for the established CP model is realized in this paper. Itsuggests how to bridge the two simulation platforms of physical system andcyber system, and construct the bridged platform to simulate the CPmodels. We successfully applied the bridged simulation platform on PV andcoordination control of PV and energy storage battery. The results prove thefeasibility of the bridged simulation platform and the effectiveness of the CPmodeling.
