Key Technologies and Challenges on Planning of Port Integrated Energy System Considering Energy Flow-logistics Coupling
The deep coupling between energy system and logistics system is one of the key characteristics of the future port integrated energy system(PIES).Planning of PIES considering energy flow-logistics coupling is of great significance for green and low-carbon transformation of ports.First,this paper presents the evolution of the PIES from three typical stages:traditional port,green port and near-zero-carbon port,and expounds its development status and trend.Then,the spatiotemporal load regulation of energy consumption in the port logistics system is analyzed,and the coupling mechanism of energy flow and logistics in the PIES is explored.On this basis,the general model of planning for PIES considering energy flow-logistics coupling is analyzed and constructed,and the characteristics and modeling elements are refined and compared from three levels of cross-port-level,port area-level and terminal-level,respectively.The research progresses of key technologies of the PIES planning at different levels are reviewed.Finally,focusing on the outstanding problems in the current PIES planning with energy flow-logistics coupling,the development directions and challenges are prospected.
