[0032] In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the following will briefly introduce the drawings required for use in the embodiments or the description of the prior art. Obviously, the following drawings are only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can be obtained based on these drawings.

[0035] Figure 3It is a schematic diagram of the control device provided by an embodiment of the present invention. Detailed implementation manners

[0036] In the following description, specific details such as specific system architectures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present invention. However, those skilled in the art should clearly understand that the present invention can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details from interfering with the description of the present invention.

[0037] To make the objectives, technical solutions, and advantages of the present invention clearer, the following will be described through specific embodiments in conjunction with the accompanying drawings.

[0038] The power grid may include multiple energy routers, which can control and schedule electrical devices. Each energy router can match multiple electrical devices. To ensure better scheduling effects and the stable operation of the power grid, the energy router will match electrical devices of the same or similar types. In this way, it is necessary to ensure that the types of electrical devices can match the types of energy routers. Currently, most of them manually configure the types of electrical devices through manual operations to facilitate matching with the energy routers.

[0039] However, the types of electrical devices are increasing continuously. If the type configuration is performed manually each time, it will not only increase the labor cost but also increase the error rate, affecting the stable operation of the power grid. Therefore, there is an urgent need for an electrical device matching method to improve the matching efficiency of electrical devices.

[0040] Refer to Figure 1 , which shows the implementation flowchart of the electrical device matching method provided by an embodiment of the present invention. As Figure 1 shown, an electrical device matching method may include:

[0041] S101, obtain the electrical parameters of the target electrical device, where the target electrical device is the electrical device to be matched.

[0042] Optionally, generally, an electrical device operates in a fixed scenario in a fixed mode, and the electrical parameters of the electrical device can characterize the type of the electrical device to a certain extent. Therefore, after the electrical device is connected to the network and before it is matched with the energy router, the electrical parameters of the target electrical device within N working cycles can be obtained. The electrical parameters can be the working current, working voltage, or working power.

[0043] S102, perform attribute extraction on the electrical parameters to obtain the target attributes of the target electrical device; where the target attributes are used to characterize the electrical characteristics of the target electrical device.

[0044] Optionally, attribute extraction can be performed on the electrical parameters to obtain the target attributes of the target electrical device.

[0045] Exemplarily, when the electrical parameter is the working current, attribute extraction can be performed on the working current to obtain multiple odd harmonic currents of the target electrical device, and the obtained multiple harmonic currents are used as the target attributes of the target electrical device.

[0046] When the electrical parameter is the working voltage, attribute extraction can be performed on the working voltage to obtain multiple odd harmonic voltages of the target electrical device, and the obtained multiple harmonic voltages are used as the target attributes of the target electrical device.

[0047] When the electrical parameter is the working power, attribute extraction can be performed on the working power to obtain multiple odd harmonic powers of the target electrical device, and the obtained multiple harmonic powers are used as the target attributes of the target electrical device.

[0048] S103, determine whether the target attribute is in the matching library. The matching library includes the attributes of historical electrical devices and the types corresponding to the attributes of historical electrical devices.

[0049] Optionally, determining whether the target attribute is in the matching library means determining whether the target attribute is the same as or similar to the attributes in the matching library. The matching library includes the attributes of electrical devices that have been matched with the energy router in the power grid and the types of electrical devices corresponding to the attributes. Generally, the working mode of an electrical device is fixed. The energy router in the power grid matches by identifying the type of the electrical device and then communicates and controls with the electrical device.

[0050] S104, when it is determined that the target attribute is in the matching library, determine the type corresponding to the target electrical device and match it with the energy router according to the type corresponding to the target electrical device.

[0051] Optionally, when it is determined that the target attribute is the same as or similar to the attributes in the matching library, the type corresponding to the same or similar attribute can be used as the type of the target electrical device, and the target electrical device is matched with the energy router in the power grid according to the type corresponding to the target electrical device.

[0052] In an embodiment of the present invention, electrical parameters of a target electrical device are obtained; the target electrical device is an electrical device to be matched; attribute extraction is performed on the electrical parameters to obtain target attributes of the target electrical device; it is determined whether the target attributes are in a matching library; the matching library includes attributes of historical electrical devices and types corresponding to the attributes of the historical electrical devices; when it is determined that the target attributes are in the matching library, the type corresponding to the target electrical device is determined, and the target electrical device is matched with an energy router according to the type corresponding to the target electrical device. Pairing the target attributes with the matching library avoids manually configuring the type of the target electrical device, improves the matching efficiency and accuracy, enables the target electrical device to be correctly connected to the power grid, and is beneficial to the stable operation of the power grid.

[0053] In some embodiments of the present invention, "determining whether the target attributes are in the matching library" in S103 above may include: for each attribute of the historical electrical devices in the matching library, calculating the attribute similarity between the attribute of the historical electrical device and the target attributes; if the attribute similarity is greater than or equal to a preset similarity threshold, it is determined that the target attributes are in the matching library.

[0054] Optionally, it can be determined whether the target attributes are in the matching library by calculating the attribute similarity between the target attributes and each attribute in the matching library. The preset similarity threshold can be set according to actual needs.

[0055] In some embodiments of the present invention, calculating the attribute similarity between the attribute of the historical electrical device and the target attributes includes: calculating the cosine similarity between the attribute of the historical electrical device and the target attributes, and using the cosine similarity as the attribute similarity between the attribute of the historical electrical device and the target attributes.

[0056] Optionally, the target attributes obtained by attribute extraction may be in the form of vectors, and the attributes in the matching library may also be in the form of vectors. The attribute similarity between the target attributes and each attribute in the matching library can be calculated by using the cosine similarity.

[0057] In some embodiments of the present invention, if the attribute similarity is less than the preset similarity threshold, it is determined that the target attributes are not in the matching library.

[0058] Optionally, after it is determined that the target attributes are not in the matching library, the type of the target electrical device can be determined by other means, and after the type of the target electrical device is determined, the target attributes and the corresponding type of the target device are added to the matching library for updating.

[0059] In some embodiments of the present invention, the electrical parameters include voltage and current. Extracting the attributes of the electrical parameters to obtain the target attributes of the target electrical device includes: performing Fourier decomposition on the voltage within N cycles to obtain the harmonic voltage of the target electrical device; performing Fourier decomposition on the current within N cycles to obtain the harmonic current of the target electrical device; and using the least squares method to fit the harmonic voltage and harmonic current within N cycles to obtain the target attributes of the target electrical device.

[0060] Optionally, the current is the normal operating current of the target electrical device, and the voltage is the normal operating voltage of the target electrical device. The voltage and current of the target electrical device within N cycles can be obtained, and Fourier decomposition is respectively performed on the voltage and current to obtain the harmonic voltage and harmonic current of the target electrical device within N cycles. The harmonic current can be odd-order harmonic current, and the harmonic voltage can be odd-order harmonic voltage.

[0061] The selected odd-order harmonic current and odd-order harmonic voltage can be fitted, and using the least squares method, the curve obtained after fitting is used as the target attribute of the target electrical device. Similarly, the attributes in the matching library can also be obtained in the same way.

[0062] Exemplarily, the third harmonic current and the third harmonic voltage within N cycles can be selected, and using the least squares method, the third harmonic current and the third harmonic voltage are curve-fitted, and the obtained third harmonic curve is used as the target attribute of the target electrical device.

[0063] To ensure the reliability of the fitting, multiple harmonic currents and harmonic voltages can be selected for fitting respectively, and the obtained results are further fitted, and the finally obtained curve is used as the target attribute.

[0064] For example, the third harmonic current, the fifth harmonic current, the third harmonic voltage, and the fifth harmonic voltage within N cycles can be selected. The third harmonic current and the third harmonic voltage are fitted to obtain a third harmonic curve; the fifth harmonic current and the fifth harmonic voltage are fitted to obtain a fifth harmonic curve. Using the least squares method, the third harmonic curve and the fifth harmonic curve are fitted to obtain an odd-order harmonic curve, and this odd-order harmonic curve is used as the target attribute of the target electrical device.

[0065] In some embodiments of the present invention, the method further includes: when it is determined that the target attribute is not in the matching library, marking and reporting the target attribute.

[0066] Optionally, when there is no attribute in the matching library that is the same as or similar to the target attribute, it indicates that the type of the target electrical device is not recorded in the matching library. In this case, the target attribute needs to be marked and reported to the server of the distribution substation for recording. After determining the type of the target electrical device, the target attribute and type of the target device are added to the matching library to expand the matching library.

[0067] Advantages of the present invention:

[0068] By judging the similarity between the target attribute of the target electrical device and the attributes in the matching library, and directly obtaining the type of the target electrical device after determining that the target attribute belongs to the matching library, and then matching the target electrical device with the energy router, the whole process does not require manual type configuration, which not only improves the matching efficiency, but also reduces the matching error rate, reduces the labor cost, improves the reliability of the target electrical device matching, and is beneficial to the stable operation of the power grid.
