摘要
The locations of marine ranch and its surrounding islands are far away from the mainland,so the cost is too high to keep power supply by laying submarine cables from the mainland.Therefore,it is necessary to build a land-sea relay networked microgrids with high propor-tion of renewable energy,which is able to provide multi-energy complementary and reli-able power for marine ranch and its surrounding islands.It is noteworthy that the networked microgrids is a typical cyber-physical system.In order to deeply reveal the cyber physical fusion characteristics of fishery networked microgrids,the morphology and key techniques of fishery networked microgrids are summarized from two aspects:physical system and cyber system.And the interactions of cyber and physical system are described,including the support from cyber system for the physical system as state perception and control,and the power support from physical system for cyber system.Based on the above interactions,the related research on coupling analysis of cyber-physical system is summa-rized.Finally,some urgently studied problems have been looked forward to in fishery net-worked microgrids cyber-physical system.
