Obviously, the drawings described below are only some embodiments recorded in this invention. For those skilled in the art, other drawings can be obtained based on these drawings.

[0036] Figure 1 This is a system block diagram of the present invention. Detailed Implementation

[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Example 1, please refer to Figure 1 As shown in this embodiment, an energy management system based on digital twins includes:

[0039] The acquisition module is used to acquire information on multiple photovoltaic energy storage power stations. The photovoltaic energy storage power station information includes the specifications of the photovoltaic energy storage power stations, the connection relationship between the photovoltaic energy storage power stations, and the location information, and to create an electronic map of the photovoltaic energy storage power stations.

[0040] The construction module, connected to the acquisition module, is used to collect 3D models of photovoltaic energy storage power stations based on photovoltaic energy storage power station information and to construct 3D geographical distribution models of photovoltaic energy storage power stations based on electronic maps.

[0041] The module is connected to the building module and is used to build virtual connection channels in a three-dimensional geographic distribution model based on the transmission channels between photovoltaic energy storage power stations. The corresponding virtual connection channel is marked with channel information, which includes power connection channel information and communication connection channel information.

[0042] The collection module, connected to the construction module, is used to collect usage information from multiple photovoltaic energy storage power stations. The usage information includes current energy storage information and historical energy storage information. Based on the usage information, the power of the photovoltaic energy storage power stations is allocated, and photovoltaic energy storage power stations with surplus energy are designated as surplus power stations.

[0043] The coordination module, connected to the collection module, is used to coordinate the energy of the photovoltaic energy storage power station based on the surplus power station to obtain coordination information;

[0044] To further explain, a photovoltaic energy storage power station refers to a new type of renewable energy power generation facility that combines photovoltaic power generation technology with energy storage technology. Photovoltaic energy storage power stations can store excess electrical energy under sunlight conditions to meet peak electricity demand or other time periods, thereby balancing power supply and demand. However, they are susceptible to network intrusion, leading to chaotic energy transmission and making it impossible to strictly follow the energy coordination of the photovoltaic energy storage power station. Furthermore, it is difficult to coordinate energy between photovoltaic energy storage power stations with insufficient or excess energy, making it impossible to guarantee the stability of energy use. Therefore, current energy storage information that does not meet the preset energy storage conditions in the application is used as supplementary information. The photovoltaic energy storage power station corresponding to this supplementary information is designated as a supplementary power station. Energy supplementation from the surplus power station to the supplementary power station is used as coordination information. This allows for the coordination of energy transmission between multiple photovoltaic energy storage power stations and enables the determination of transmission instructions, avoiding energy transmission errors caused by network intrusion.

[0045] In one embodiment, the acquisition module includes:

[0046] The data acquisition unit is used to collect the specifications of photovoltaic energy storage power stations, the connection relationships between photovoltaic energy storage power stations, and location information as photovoltaic energy storage power station information;

[0047] The map acquisition unit is used to acquire electronic maps of multiple photovoltaic energy storage power stations based on satellite maps;

[0048] To elaborate further, the first step is to obtain information about the photovoltaic energy storage power stations that need to be managed. This information includes the specifications of the photovoltaic energy storage power stations, the connection relationships between them, and their location information. This information forms the basic information of the photovoltaic energy storage power stations. Then, based on the location information of the photovoltaic energy storage power stations, electronic maps are collected between multiple photovoltaic energy storage power stations using satellite maps. This allows for a better understanding of the location and basic information of the photovoltaic energy storage power stations, which facilitates subsequent energy management.

[0049] In one embodiment, the building module includes:

[0050] The building unit is used to collect multi-angle images of the photovoltaic energy storage power station and build a three-dimensional model of the photovoltaic energy storage power station based on the multi-angle images;

[0051] The marking unit is used to mark key locations of the photovoltaic energy storage power station in the 3D model of the photovoltaic energy storage power station.

[0052] The management unit is used to arrange the three-dimensional models of multiple photovoltaic energy storage power stations according to their geographical locations based on an electronic map to obtain a three-dimensional geographical distribution model.

[0053] In one embodiment, the marking unit includes:

[0054] The location acquisition unit is used to acquire the location of each component in the photovoltaic energy storage power station and determine the importance of each component in the photovoltaic energy storage power station;

[0055] The division unit is used to divide the photovoltaic energy storage power station into management areas based on the importance of each component in the photovoltaic energy storage power station, and to mark the key locations in the 3D model;

[0056] To further explain, acquiring multi-angle images of the photovoltaic energy storage power station allows us to understand its external shape. Based on this shape, a 3D model of the power station can be constructed. After obtaining the 3D model, the locations of the components within the power station are collected. The importance of each component is used to determine key locations in the 3D model. Here, component importance refers to both its role in the operation of the photovoltaic energy storage power station and its social value (in this case, the component's price). The formula for calculating the importance of each component in the photovoltaic energy storage power station is as follows: Where ZY represents the importance of each component in the photovoltaic energy storage power station, and S represents the social value. This is a coefficient representing the degree of influence of the module in the operation of the photovoltaic energy storage power station. It should be noted that S and... The larger the value of ZY, the greater the importance of each component in the photovoltaic energy storage power station. It also indicates that the component of the photovoltaic energy storage power station is the part that needs to be valued, which can greatly improve the management of the photovoltaic energy storage power station. Then, based on the importance, the key locations of the photovoltaic energy storage power station are divided, and then the key locations are marked in the 3D model. The key locations are regarded as the parts that need to be focused on in the 3D model, which facilitates the energy management of the photovoltaic energy storage power station.

[0057] In one embodiment, the building module includes:

[0058] A building unit is used to obtain the connection relationship between various photovoltaic energy storage power stations, and a virtual connection channel is built in the three-dimensional geographical distribution model based on the connection relationship between photovoltaic energy storage power stations;

[0059] The setting unit is used to set the enabling conditions for the corresponding transmission channel and mark the enabling conditions in the virtual connection channel;

[0060] The information marking unit is used to mark the power connection channel information and communication connection channel information in the virtual connection channel corresponding to the three-dimensional geographic distribution model and to use them as channel information.

[0061] To further explain, after obtaining models of multiple photovoltaic energy storage power stations, they remain independent. Therefore, it is necessary to collect the connection relationships between these power stations. These connection relationships represent the actual connection channels between the photovoltaic energy storage power stations. Based on these connection relationships, virtual connection channels are built in the 3D geographic distribution model. These virtual connection channels can be power connection channels and communication connection channels. Opening conditions are then set according to these channels, facilitating energy scheduling and management between the photovoltaic energy storage power stations. After obtaining the virtual connection channels, the power connection channel information and communication connection channel information are combined and marked in the 3D geographic distribution model. This makes the data more clearly represented by the 3D geographic distribution model, facilitating subsequent management of the 3D geographic distribution model and energy control.

[0062] In one embodiment, the setting unit includes:

[0063] The numbering unit is used to obtain the photovoltaic energy storage power station connected to the virtual connection channel based on the virtual connection channel, and to assign an identity number to the photovoltaic energy storage power station. The integrated number of the identity number of the photovoltaic energy storage power station connected to the virtual connection channel is used as the number of the virtual connection channel, and the number of the virtual connection channel is synchronized with the transmission channel between the photovoltaic energy storage power stations.

[0064] The binding unit is used to set the opening conditions based on the virtual connection channel. The opening conditions include the integrated number of the identity number of the photovoltaic energy storage power station connected to the virtual connection channel and the opening identification feature of the virtual connection channel. The opening identification feature includes a first feature and a second feature. The first feature and the second feature are respectively bound to the photovoltaic energy storage power station connected to the virtual connection channel, and the opening conditions are synchronized to the transmission channel.

[0065] To further explain, each photovoltaic (PV) energy storage power station is assigned an identification number. The integrated identification number of the PV energy storage power station connected to the virtual connection channel is used as the virtual connection channel's number. This yields both the PV energy storage power station's identification number and the virtual connection channel's identification number. These two numbers indicate that the virtual connection channel is used to connect the two PV energy storage power stations. Then, activation conditions are set for the virtual connection channel. These conditions include the integrated identification number of the PV energy storage power station connected to the virtual connection channel and the activation identification features of the virtual connection channel. These features include a first feature and a second feature. The first and second features are then bound to the corresponding PV energy storage power stations connected to the virtual connection channel. Specifically, the first feature is bound to one of the PV energy storage power stations connected to the virtual connection channel, and the second feature is bound to the other. Multiple management terminals for the PV energy storage power stations are set up, and the first and second features are assigned to each of these management terminals. Activating the first and second features requires... Authorization is granted by multiple management terminals. The authorization method for the first and second features is as follows: both the first and second features are code boxes corresponding to the number of management terminals. The code data in the code boxes is variable; management terminals can arbitrarily fill in the code data in their respective code boxes. The data in the code boxes of the first and second features must be identical to complete the identification between them. After identification, a transmission channel can be opened. For example, when energy needs to be transmitted between two photovoltaic energy storage power stations, the corresponding transmission channel can be determined by integrating the identification numbers of the two photovoltaic energy storage power stations. This is displayed as a virtual connection channel in the 3D geographic distribution model. When the two photovoltaic energy storage power stations are commanded by energy regulation, they will automatically invoke the first and second features to open the transmission channel, which is displayed as the opening of the virtual connection channel in the 3D geographic distribution model. This allows for smooth energy regulation of the photovoltaic energy storage power stations. Under normal circumstances, the transmission channel is closed, preventing energy transmission and better ensuring the stability of energy storage, thus avoiding network intrusion from affecting energy regulation.

[0066] In one embodiment, the collection module includes:

[0067] The data acquisition unit is used to collect current and historical energy storage information from multiple photovoltaic energy storage power stations as usage information.

[0068] The distribution unit is used to distribute the energy of the photovoltaic energy storage power station through the transmission channel based on the usage information, collect the surplus energy storage as public energy, and display the distribution process through a three-dimensional geographical distribution model.

[0069] To further explain, after setting the management and transmission channel opening conditions of the photovoltaic energy storage power station, it is necessary to collect the current energy storage information and historical energy storage information of multiple photovoltaic energy storage power stations as usage information. In this way, the energy usage information and production capacity information of the photovoltaic energy storage power station can be obtained. The excess energy of the photovoltaic energy storage power station can be shared as public energy, and the allocation process can be displayed through a three-dimensional geographical distribution model. This ensures that the energy meets the daily operation of the photovoltaic energy storage power station and can also supplement the energy of other photovoltaic energy storage power stations.

[0070] In one embodiment, the coordination module includes:

[0071] The judgment unit is used to obtain the current energy storage information of the photovoltaic energy storage power station, and to take the current energy storage information that does not meet the preset energy storage conditions as information to be supplemented, and to take the photovoltaic energy storage power station corresponding to the information to be supplemented as the power station to be supplemented.

[0072] The coordination unit is used to coordinate energy replenishment from the surplus power station to the power station to be supplemented.

[0073] To further explain, among multiple photovoltaic energy storage power stations, there may be situations of energy surplus and energy shortage. Photovoltaic energy storage power stations with excess energy are designated as surplus power stations. The current energy storage information of photovoltaic energy storage power stations is obtained, and the current energy storage information that does not meet the preset energy storage conditions is designated as information to be supplemented. The photovoltaic energy storage power stations corresponding to the information to be supplemented are designated as power stations to be supplemented. Energy supplementation of power stations to power stations by surplus power stations is used as coordination information. This can coordinate the energy transmission between multiple photovoltaic energy storage power stations and can determine the transmission instructions, avoiding energy transmission errors caused by network intrusion.

[0074] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
