Multiple-energy Corordinative Planning And Control Of Energy Internet

The continuous improvement of human productivity and quality of life has led to a surge in demand for energy,and traditional fossil energy has gradually shown signs of fatigue in both reserves and environmental issues.The energy crisis and environmental pollution have become hot topics in recent years,stimulating people to explore and utilize renewable,low-pollution and high-efficiency energy.The energy Internet is an energy utilization system that combines energy and information technology,which greatly improves the penetration and utilization of renewable energy in the power grid.The planning and operation control of the energy Internet is the basis for the development of the energy Internet,and it is a key step in the theoretical implementation of the actual project.This paper studies the planning and operation control of the energy Internet from three aspects: the planning of the campus-level energy LAN,the planning of the regional energy WAN,and the dynamic modeling of the energy router.In the general trend of urbanization and functional regionalization,the most basic and typical component of the energy Internet is the integrated energy system with the industrial park as the carrier.In addition to the basic energy supply,energy conversion,energy storage and other components,these systems also have energy components with regional industrial characteristics.At present,the planning research on the energy Internet has neglected its planning research.This paper analyzes the park from three aspects: energy,environment and load.Based on this,it constructs the physical planning framework of the park-level energy LAN.It proposes the planning method of the park’s internal multi-energy coordination and optimization operation.At the same time,because of the decentralized nature of industrial parks,they are often planned and operated separately,resulting in low overall efficiency of energy,environment and economy in the region.This paper proposes the concept of virtual energy router.Based on the energy hub expansion model and the hybrid power flow model,an association model considering the multi-energy coupling of virtual energy router is constructed,and a planning method including the internal routing algorithm of virtual energy router is proposed.The scaled benefits of virtual energy routers in the region.In addition,the energy router is quite complicated due to its internal multi-energy coupling characteristics.This paper analyzes the coupling mechanism of energy routers,builds a multi-time scale dynamic model of energy routers,and based on this,discusses the coupling mechanism and stability of energy routers,and provides a research basis for the operation control of energy Internet.
