The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments. The following examples are intended to illustrate the present invention, but not to limit the scope of the present invention.

An embodiment of the present invention provides an SDN-based energy router. FIG. 1 is a schematic structural diagram of the SDN-based energy router provided by an embodiment of the present invention. The device includes: an SDN controller and various functional modules; wherein the The SDN controller is configured to generate a control strategy according to the preset control requirements of the energy packet to be transmitted, and send the control strategy to the corresponding functional module; the functional module is configured to receive the control strategy sent by the SDN controller, and then send the control strategy to the corresponding functional module.

Specifically, the functional architecture of the SDN-based energy router is divided into two layers, the upper layer is the SDN controller, and the lower layer is the software and hardware functional modules that implement various specific functions, and the functional modules are mainly responsible for energy access, transmission and management, Function module 1, function module 2, and function module 3 in FIG. 1, this embodiment is not limited to these three function modules. The SDN controller is an energy router control system based on the idea of SDN (Software Defined Network, software defined network), similar to a computer operating system, and realizes unified control and management of each functional module in the energy router, so as to be simple, efficient and intelligent. The overall architecture of the energy router that realizes the functions of energy production, transmission, routing and conversion, and flexibly controls, operates and operates the various functions of the energy router. The simple, efficient and scalable energy router function in the energy internet is realized through the SDN controller. Different from the traditional SDN technology application scenario, this embodiment does not apply the SDN technology to the design of the entire energy Internet, but only uses the SDN technology inside the energy router to realize the management and control of the energy router, which is equivalent to establishing an energy router inside the energy router. A small SDN operating system.

The SDN controller generates or establishes a control strategy inside the energy router according to previous operating experience and actual operating requirements. The SDN controller may establish the control strategy using learning and optimization techniques such as artificial intelligence and reinforcement learning. The SDN controller actively or passively delivers the control strategy to the corresponding functional modules according to the actual operation requirements of the lower-layer functional modules. The SDN controller may request the corresponding control policy to be sent to the corresponding functional module in the form of a flow entry according to the preset control policy that is most commonly used or most likely to be used. For example, when a new device is connected, the SDN controller acquires a preset control strategy requirement corresponding to the type and model of the new device according to the type and model of the new device, and generates a control strategy according to the measurement requirement. The function module acquires a control strategy matching the header information of the energy packet to be transmitted in the function module, and transmits the energy packet to be transmitted according to the control strategy matching the packet header information and the packet header information .
