Description

Topological modeling method and device for energy system Technical Field

[0001] The present invention mainly relates to the field of computer software, and in particular to a topology modeling method and device for an energy system. Background Art

[0002] In an integrated energy management system, users need to constantly adjust the connection relationships between different energy devices and the parameter values ​​of each energy device, which is very time-consuming. In addition, during the operation of the integrated energy system, the topology of the energy system needs to be maintained and adjusted to ensure that the integrated energy system operates in an optimal manner. Currently, general-purpose drawing software is commonly used to establish the topology of the energy system. However, this type of topology has no practical physical meaning and is not suitable for the maintenance and adjustment of the topology during the operation of the energy system. It also has poor scalability. Alternatively, simulation software is used to establish the topology of the energy system. However, the modeling performance of simulation software is poor and it still cannot achieve the ideal modeling function.

[0055] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0056] As used in this application and the claims, unless the context clearly indicates otherwise, the words "a," "an," "an," and / or "the" are not intended to refer to the singular but may include the plural. Generally speaking, the terms "comprises" and "include" only indicate the inclusion of the steps and elements specifically identified, and these steps and elements do not constitute an exclusive list. A method or apparatus may also include other steps or elements.

[0057] The present invention provides a topology modeling method for an energy system. FIG1 is a flowchart of a topology modeling method 100 according to an embodiment of the present invention. As shown in FIG1 , the topology modeling method 100 includes:

[0058] Step 110: Obtain mechanism models of different types of energy devices.

[0059] The energy system includes different types of energy devices, which can be heat pumps, cold sources, refrigerators, fans, photovoltaics, and other types of energy devices. Each type of energy device has a mechanism model, that is, the physical meaning of the operation of the energy device. The mechanism model includes multiple attributes, each attribute has a corresponding parameter value, some parameter values ​​are fixed, and some parameter values ​​are adjustable. The attributes of the mechanism model can be predefined by the user or obtained through other means. For example, the mechanism model of a heat pump may include device name, device type, input state calibration, input flow data type, output flow data type, input flow power, output flow power, efficiency, device availability, revenue power, cost per kilowatt-hour, cost per kilowatt, cost per hour, etc., among which the device name and device type are fixed parameters, the input state calibration and device availability are variable non-numeric parameters, and the input flow data type, output flow data type, input flow power, output flow power, efficiency, revenue power, cost per kilowatt-hour, cost per kilowatt, and cost per hour are variable numeric parameters.

[0060] FIG2 is a schematic diagram of an implementation environment 200 of a topology modeling method according to an embodiment of the present invention. As shown in FIG2 , implementation environment 200 includes a user 210, a user interface 220, a server 230, and a cloud 240. User 210 can be a front-end engineer, a system engineer, or a field engineer. User interface 220 serves as the input and output interface between user 210 and the system. Server 230 and cloud 240 store mechanism models of different types of energy devices. The front-end can access the mechanism models of energy devices from server 230 or cloud 240. User 210 establishes a topology model of the energy system by operating user interface 220. The established topology model is then sent to server 230 or cloud 240 for storage and subsequent access.

[0061] Step 120 : Display icons of different types of energy devices and connection lines for connecting different types of energy devices.

[0062] Different types of energy devices are displayed in the form of icons. The icons can be abstract patterns representing a type of energy device. Users can distinguish and select the icon of the target energy device by browsing the icons. The connection lines used to connect different types of energy devices are also displayed in the form of icons. Users can select connection lines to connect the selected energy devices. The connection lines can include one-way connection lines and bus connection lines. Figure 3 is a schematic diagram of a user interface 300 of a topology modeling method according to an embodiment of the present invention. As shown in Figure 3, the user interface 300 includes a first display area 310 and a second display area 320. The first display area 310 displays icons of connection lines. The connection lines include one-way connection lines and bus connection lines. The second display area 320 displays icons of different types of energy devices, with three energy device icons arranged in each row. The user can select the relevant energy device from the second display area 320 and select connection lines from the first display area 310 to connect the selected energy devices.

[0063] Step 130 : receiving the plurality of energy devices selected by the user through the operation icons and the connection relationships between the plurality of energy devices, as well as the user's adjustment of the attribute parameters of the mechanism models of the plurality of energy devices, to establish a topological structure model of the energy system.

[0064] Users can select the icon of the corresponding energy device in the icon area, drag the selected energy device, adjust the property parameters of the selected energy device, and select connecting lines in the chart area to connect multiple energy devices to establish a topological structure model of the energy system. This topological structure can be used for subsequent simulation analysis of the energy system, etc. To this end, users can quickly, conveniently and flexibly establish a topological structure model of the energy system by operating the icon of the energy device. In addition, the energy device has a mechanism model, so the established topological structure model also has actual physical meaning and can be used for subsequent simulation analysis of the energy system.

[0065] As shown in FIG3 , the user interface 300 also includes a third display area 330 and a fourth display area 340. The third display area 330 is an operation area for the topology model, and the fourth display area 340 is a display area for the mechanism model. The mechanism model includes eight attributes, A, H. It should be understood that this mechanism model is merely an example and should not be construed as the actual number of attributes in the mechanism model. In FIG3 , the user selects the hot water flue gas lithium bromide unit icon from the second display area 320 and drags it to the third display area 330 to create the hot water flue gas lithium bromide unit 31. In the fourth display area 340 , the user adjusts the attributes of the mechanism model of the hot water flue gas lithium bromide unit 31. Then, the user selects the heat pump icon and drags it to the third display area 330 to create the heat pump 32. In the fourth display area 340 , the user adjusts the attributes of the mechanism model of the heat pump 32. In the first display area 310 , a one-way connection line is selected to connect the hot water flue gas lithium bromide unit 31 and the heat pump 32. This process continues until all energy devices have been added and connected to establish the topology model of the energy system.

[0066] In some embodiments, the method includes: obtaining mechanism models of different types of energy devices from a server, receiving multiple energy devices selected by a user through a browser operation icon and the connection relationship between the multiple energy devices, and the user adjusting the parameters of the mechanism models of the multiple energy devices. Specifically, the topology modeling method in the embodiments of the present invention adopts a browser / server (B / S) architecture, that is, the mechanism models of different types of energy devices are stored in the server, and the user establishes a topology model of the energy system through the display interface of the browser. To this end, by adopting the browser / server (B / S) architecture, the topology modeling method is made more lightweight and the efficiency of topology modeling is improved.

[0067] In some embodiments, the energy system includes multiple energy subsystems, each of which includes multiple energy devices. The method further includes: receiving user settings for parent nodes in the energy subsystems. Figure 4 is a multi-level schematic diagram of a user interface display according to one embodiment of the present invention. The first number in the brackets after the energy subsystem name represents the code of the energy subsystem, and the second number represents the code of the parent node of the energy subsystem set by the user. As shown in Figure 4, the parent node of cold source 24 and power grid 25 is system 23, the parent node of high-temperature refrigerator 27, low-temperature refrigerator 28, and ice maker assembly 31 is cold source 24, and the parent node of low-temperature refrigerator 29 and high-temperature refrigerator 30 is power grid 25. To this end, by receiving user settings for parent nodes in the energy subsystems, a multi-level energy system structure can be established, making it easier for users to understand the logical relationships between energy subsystems in the energy system.

[0068] In some embodiments, receiving user adjustments to attribute parameters of the mechanism model of the energy device includes: recommending default attribute parameters for the mechanism model of the energy device, and receiving user adjustments to the default attribute parameters. Specifically, some attributes in the mechanism model of the energy device may be recommended by the system. The system may recommend default attribute parameters through an algorithmic model, and the user may modify the default attribute parameters. To this end, by recommending default attribute parameters for the mechanism model of the energy device, the user can quickly set the attribute parameters in the mechanism model, thereby improving the efficiency of topology modeling.

[0069] In some embodiments, the method further includes: receiving information about multiple energy devices selected by a user operating an icon and the connection relationships between the multiple energy devices, and authenticating the user before the user adjusts the attribute parameters of the mechanism models of the multiple energy devices. As shown in FIG2 , implementation environment 200 further includes an authentication service unit 220 . Before user 210 uses user interface 220 , authentication service unit 220 authenticates user 210 . Therefore, by authenticating the user, system security can be improved.

As shown in FIG5 , in the energy system, natural gas from a natural gas supply 501 is supplied to a first gas-fired hot water boiler 502, a second gas-fired hot water boiler 504, and a third gas-fired hot water boiler 506. The first gas-fired hot water boiler 502, the second gas-fired hot water boiler 504, and the third gas-fired hot water boiler 506 consume the natural gas to generate kinetic energy or thermal energy. A first economizer 503, a second economizer 505, and a third economizer 507 are respectively installed at the tail of the first gas-fired hot water boiler 502, the second gas-fired hot water boiler 504, and the third gas-fired hot water boiler 506 to recover the waste heat of the exhaust gas. Finally, after the flue gas is exhausted 512, the natural gas from the natural gas supply 501 is also supplied to a first gas-fired internal combustion generator 508 and a second gas-fired internal combustion generator 510. The first gas-fired internal combustion generator 508 The second gas internal combustion generator 510 consumes natural gas to generate electricity, which is supplied to the first hot water flue gas lithium bromide unit 509 and the first hot water flue gas lithium bromide unit 511 respectively. The output of the first hot water flue gas lithium bromide unit 509 and the first hot water flue gas lithium bromide unit 511 passes through the flue gas exhaust 512.
