Multi-energy flow coupling is one of the key features of the Energy Internet and integrated energy system distinguishing them from the smart grid. Energy management for multi-energy flow is faced with three main challenges

multiple-energy flow coupling

multi-time scale and multi-management body. This paper summarizes the research status and prospects of the research trends and focal points

namely

multi-energy flow real-time modeling and state estimation; multi-energy flow multi-time scale security analysis and security control; multi-energy flow hybrid-time scale optimization and scheduling; design

development and validation of energy management system(EMS)for multi-energy flow. This work is supported by National Basic Research Program of China(973 Program)(No. 2013CB228203)and National Natural Science Foundation of China(No. 51537006
