Abstract:

To improve the energy and information exchange efficiency between devices and energy nodes in an integrated energy system (IES), reduce energy production and transmission costs, and achieve efficient conversion and flexible allocation of multiple energy sources, a centralized-distributed integrated energy system based on energy hubs(EH) is constructed. According to the model of the IES,the cyber physical system based on the cluster of sub-cyber physical systems is defined. On the information end of the IES, the operational model for each sub-cyber physical system and information interaction model for sub-information system servers in an EH node are given. Being exposed to cyber security threats, the integrated energy cyber physical system comprehensively takes complementarity of different energy sources, network transmission and distribution of energy, energy storage, clean energy's dynamic access to the grid and other operational requirements into considerations, and adopts a three-element and three-layer secure trusted protection architecture based on trusted computing technology. Starting from protecting every energy node, this protection system constructs a protection mechanism based on node trust, network connection trust and application trust, to ensure the safe and reliable operation of the IES.

Key words: integrated energy system, cyber physical system, energy complementarity, energy storage, clean energy, security protection architecture, trusted computing
