Embodiment Construction

[0024] Embodiments will be described below in conjunction with the accompanying drawings.

[0025] An energy router is also called an energy router, and CN201210261558.6 discloses an energy router. The power router has two types of interfaces: power supply and load. The power supply interface includes a dedicated interface for mains power, a distributed non-renewable power supply interface, and a common distributed renewable power supply (or energy storage device) interface. The bus includes a DC bus and two AC buses. The DC bus and the AC bus II are collectively called the distributed power bus. They are connected through AC and DC converters to connect distributed power and energy storage equipment. The switch array includes a one-way grid-connected switch and several two-way load switches. In addition, the power router also includes a detection module, a communication module, a control unit, and the like. Its topology see figure 1 .

Abstract

The invention relates to an SDN-based electric energy router dispatching method, which comprises the steps as follows: when a distributed power supply accessed to an electric energy router can meet the requirements of loads of the electric energy router, the electric energy router supplies electricity to the loads first by use of the distributed power supply ; when the distributed power supply cannot meet the requirements of the loads, the electric energy router supplies electricity to the loads first by use of energy storage equipment ; when the energy storage equipment cannot meet the requirements of the loads, the electric energy router transmits a corresponding signal and electric parameters of the loads which cannot be normally powered to an SDN controller; the SDN controller receives the signal and then transfers a corresponding amount of electric energy from an electric supply trunk network to supply electricity to the loads; when the generated electricity of the distributed power supply is continuously increasing and simultaneously meets the working requirements of a plurality of loads, the electric energy router controls a switch array module to connect the distributed power supply and the corresponding loads and makes the loads powered. According to the SDN-based electric energy router dispatching method, the global optimum energy control can be achieved.

Description

technical field [0001] The invention relates to an SDN-based power router scheduling method. Background technique [0002] In recent years, on the one hand, non-renewable energy has been decreasing and environmental problems have become increasingly prominent. On the other hand, people’s requirements for living environment comfort have continued to increase. utilization and meet the growing demand for electric energy. [0003] One of the important symbols of smart grid is the organic combination of power grid and renewable energy. There are two forms of renewable energy power generation: distributed power generation and centralized power generation. Distributed power generation is usually directly connected to the low-voltage distribution network and supplied to users, which reduces line losses and reduces the construction cost of the power system. [0004] Aiming at the challenges faced by the smart grid in terms of power access, power control, and power transmission, ref...
