Multi-energy complementary technology

which is the physical foundation of Energy Internet

can make full use of distributed energy resources and renewable energy resources. It is of great significance to improve the renewable energy ratio and comprehensive energy efficiency. From the perspective of the renewable energy sources utilization

this paper introduced the development background of multi-energy system and Energy Internet. The key technologies of multi-energy complementary development were also discussed. In particular

the research status of multi-energy system analysis and planning technology

energy management technology

coordinated optimization control system and energy storage technology were analyzed. It also pointed out the development trends of multienergy complementary technology: an integrated local power system with a high proportion of fluctuating renewable energy sources in electricity generation

transmission

distribution

storage and utilization.
