A SDN-based energy internet control layered architecture and scheduling method

Abstract

The invention discloses an energy internet control layered architecture based on SDN (Software Defined Networking) and a scheduling method, and belongs to the field of a communication network and energy scheduling control. The energy internet control layered architecture is divided into a local area energy layer and a wide area energy layer; and each root controller of the wide area energy layer is respectively connected with at least one node controller of the local area energy layer. The energy internet scheduling method comprises the following steps of: firstly, initializing an energy and information network state; then, when an entity of a certain energy micro net is short of energy, sending an energy rating request message to the node controllers, sending energy balance inquiry messages to all other entities by the node controllers, judging whether a certain entity responds inside the energy micro net, and if yes, completing energy scheduling in the energy micro net; or, reporting to the corresponding root controllers by the node controllers, and completing energy scheduling across the energy micro nets. The energy internet control layered architecture based on SDN and the scheduling method have the advantages that by layered SDN control, a load of a single SDN controller is reduced, supervision capability of the network is reinforced, and a supervision range is enlarged.

Description

technical field [0001] The invention belongs to the field of communication network and energy scheduling control, relates to an energy internet control architecture, in particular to an SDN-based energy internet control layered architecture and a scheduling method. Background technique [0002] Energy Internet refers to a shared network supported by information and communication technology that can effectively accommodate large-scale distributed clean energy, intelligent and open wide-area energy interconnection. Energy Internet uses advanced information and communication technology, power electronics technology and intelligent management technology to achieve coordination between distributed power generation equipment, energy storage equipment and loads in a large range, and change the energy production mode from large-scale centralized fossil energy to distributed energy. Renewable energy for the transition. [0003] Applications such as energy trading and demand manageme...

AI Technical Summary

Problems solved by technology

[0006] In the current smart grid and energy Internet architecture, communication equipment and electrical equipment are separated, which cannot meet the needs of energy control integration, and there is a lack of energy control integration scheduling methods and corresponding control equipment.

On the other hand, as a pure network control protocol, SDN currently has no technology to adapt it to the energy control integration scenario of the Energy Internet.
