Problems solved by technology

[0004] In the existing technology, the system design and related definition and control are mainly aimed at the whole Energy Internet, and the sub-module of the Energy Internet-the local Energy Internet is less analyzed. At the same time, in the research of the Energy Internet, the energy management system The control is very broad, and the timeliness is not enough. It lacks reliable and effective algorithm support, and cannot make efficient decisions.

Embodiment 1

[0086] The energy router in the local domain energy network provided in the present invention exists on the outer port and the inner port on the overall architecture, passing the control commands to their control commands by controlling the module, and classify these ports into charging, discharge and autonomy according to energy flow. That is, there is no electrical energy exchange with the outside world).

[0087] Each port needs to set the range of energy exchange power, the electricity price range, the scope of power generation, and electricity requirements of electricity or electricity.

[0088] Such as figure 1 As shown, the energy management method of the energy router in the local energy network provided by the present invention, including:

[0089] S1, the ownership determination control algorithm based on each port;

[0090] S2, the measured power based on each port determines the operation of the energy router;

[0091] S3, based on the control algorithm and operationa...

Embodiment 2

[0113] Such as Figure 6 As shown, the energy management method of the energy router in the local area energy network provided in this embodiment, including; first, the control algorithm is connected to the inner port and the external port to access the device, press Figure 7 It is judged that the ownership of each port, the operation of charging, discharging, or autonomous operation based on energy routers, and the ownership of the portions, the control algorithm includes control algorithm A, control algorithm B and control algorithm C.

[0114] Second, judge the operation of the energy router;

[0115] The execution control logic is then determined based on the control algorithm and the operating conditions, and the corresponding control logic is performed.

[0116] Finally, after the first next control command, the trend starts flowing and transmits the required parameters up, and the control algorithm continues to send the control command after executing the obtained paramete...

Embodiment 3

[0169] Based on the same inventive conception, the present invention also provides an energy management system of energy routers in a local energy source Internet, including;

[0170] Control algorithm module, used to determine control algorithm based on ownership of each port;

[0171] Operation module, used to determine the operation of the energy router based on the measured power of each port;

[0172] Select the module for selecting the control algorithm and operational conditions from preset control logic;

[0173] Execute the module for issuing a control command to each port based on the selected control logic.

[0174] In an embodiment, the control algorithm module includes:

[0175] Determine all rights units, used to determine ownership of each port based on the owner of each port connection device;

[0176] The port includes an external port and a plurality of pair ports; the external port is connected to the grid or other energy router; the inner port is connected to o...

Abstract

The invention provides an energy management method and system for an energy router in a local energy internet. The method comprises the following steps: firstly, determining a control algorithm basedon the ownership of each port; secondly, judging the operation condition of the energy router based on the actually measured power of each port; making selection from a preset control logic based on acontrol algorithm and an operation condition; and finally, issuing a control command to each port based on the selected control logic. The ownership and the operation condition of each port are classified, control logic is provided for the ownership and the operation condition of each port respectively, it is guaranteed that the energy router can meet all application scenes and customer requirements, the economic index is clear, stored energy serves as the independent operation condition, and frequent switching of a router operation mode and a control algorithm caused by change of an energy storage charging and discharging state is avoided.

Description

Technical field [0001] The present invention relates to the field of energy management in an energy source, and more particularly to an energy management method and system of energy routers in a local energy source Internet. Background technique [0002] Energy Internet is based on energy, integrated heat, cold, gas and other energy, comprehensive utilization of Internet and other technologies, deep fusion energy systems and information communication systems, coordinating multi-energy production, transmission, distribution, storage, conversion, consumption, and transactions, Open energy internet network with efficient, clean, low carbon, safety features. Local Energy Internet is a regional energy network. The energy Internet system consists of a local domain energy Internet, and the core node in the local energy network is an energy router. It undertakes the circulation of energy internal and external energy, energy. Scheduling. [0003] At present, it is basically a research con...
