Description

Technology Field

[0001] The present invention relates to an energy storage system modeling platform, and more specifically, to an energy storage system modeling platform that provides a user with a library necessary for energy storage system modeling in the form of an application, allowing the user to easily model by installing it on their terminal. Background Technology

[0003] Generally, an Energy Storage System (ESS) installed in power plants driving large-scale power grids or in buildings with high power consumption consists of multiple batteries. More specifically, the batteries of an ESS can generally be composed of multiple battery racks, each consisting of multiple battery modules, and as a result, numerous batteries can be assembled and installed in special spaces such as air-conditioned buildings or containers. In this case, a Battery Management System (BMS) is installed in the multiple battery racks to monitor and control control targets such as voltage, current, temperature, and circuit breakers.

[0004] Meanwhile, a Power Conversion System (PCS) is installed in the ESS and controls the charging and discharging of the battery by controlling the power supplied from the outside and the power supplied from the battery rack to the outside, and an Energy Management System (EMS) connected to the PCS controls the output of the PCS based on the monitoring and control results of the BMS described above.

[0005] Figures 1 and 2 are diagrams illustrating the connection between the battery rack and the PCS of a conventional ESS.

[0006] At this time, referring to FIGS. 1 and FIGS. 2, there is an ESS (1) in which a battery rack (2) connected in parallel is connected to one PCS (3), or an ESS (4) in which a PSC (6) is individually connected to each battery rack (5) connected in parallel, and the specification design method of the ESS must be performed differently in accordance with the connection configuration between the battery rack and the PCS of the ESS.

[0007] More specifically, in the case of a specification design method for an ESS (1) having a configuration in which a battery rack (2) connected in parallel is connected to a single PCS (3), the output of the PCS (3) is fixed and set to the required output of the ESS (1), and the specifications of the ESS (1) are designed by changing the capacity and number of the battery racks (2).

[0008] However, in the case of an ESS (4) having a configuration in which a PSC (6) is individually connected to each battery rack (5) connected in parallel, the output of the PCS (6) connected to each battery rack (5) cannot be fixed to the required output of the ESS (4), and the capacity of each battery rack (5) is fixed, so the initial capacity according to the required specifications of the ESS (4) cannot be calculated.

[0009] Furthermore, for energy storage systems, it is important to identify the capacity of the locations requiring power, such as temperature-controlled logistics systems or buildings, and to design the target capacity accordingly. Prior art literature

It should also be understood that the location or arrangement of individual components within each disclosed embodiment may be changed without departing from the spirit and scope of the invention. Accordingly, the following detailed description is not intended to be limiting, and the scope of the invention is limited only by the appended claims, including all equivalents to those claimed therein, provided appropriately described. Similar reference numerals in the drawings refer to the same or similar functions across various aspects.

[0032] Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the drawings.

[0033] FIG. 3 shows a configuration diagram of an energy storage system platform according to an embodiment of the present invention, and FIG. 4 shows the configuration of an energy storage system platform according to an embodiment of the present invention.

[0034] The energy storage system platform (10) provides libraries necessary for energy storage system modeling in the form of applications, and the user terminal (20) can download and use them. When the application is downloaded, it is automatically added to a modeling program such as Revit, and the user terminal is synchronized with the energy storage system platform (10) to use the latest libraries provided by the platform.

[0035] The present invention is an energy storage system modeling platform (10) that provides an energy storage system modeling application to a user terminal (20) so that it becomes an add-in to a design modeling program installed on the user terminal,

[0036] The above energy storage system modeling application is,

[0037] The system is characterized by including: a library storage unit (100) that stores an energy storage system library containing information related to the energy storage system, including specifications of a battery module and a rack in which the battery module is installed; a library synchronization unit (200) that installs the library stored in the library storage unit on a user terminal and creates a folder in the added-in modeling program to synchronize the user terminal with the library storage unit; an interface providing unit (300) that provides an interface for a user to input information required for modeling; and a modeling unit (400) that calculates the number of battery racks according to the information input by the user, and arranges the location of the racks and models according to the number of battery racks.

[0038] And it may further include a report writing unit (500) that writes the modeling results in the form of a report.

[0039] The energy storage system modeling platform may provide access to the library for members to download via a website. Since general procedures can be used for member management and authentication, a detailed description is omitted in this invention.

[0040] Since the library synchronization unit (200) synchronizes the library folder of the user terminal with the library provided by the platform, the user can provide the latest library to members while updating the latest library provided by the platform.

[0041] The above terminal management unit (200) synchronizes the user terminal with the library of the website when the user (member) terminal accesses the website and downloads the library.

[0042] When modeling, the Revit program is generally used. When a user terminal downloads the application, the library synchronization unit (200) creates a folder in the Revit program and synchronizes it. The menu of the created add-in (yedaeng) can be displayed in the Revit program.

[0043] Figure 5 shows an example of the 'YEDAENG' menu being added as an add-in to the Revit program, and Figure 6 shows an example of the library that appears when the added 'YEDAENG' menu is clicked.

[0044] The interface providing unit (300) provides an interface that allows input of necessary information for modeling when synchronization with the user terminal is completed.

[0045] The interface providing unit (300) can provide an interface that allows a user to specify the location where the battery module is installed, by providing a graphic form such as a plan view and a 3D view of the building, based on the ESS library, an energy storage system including a battery module, PCS, a DC distribution board, and a grid connection board, based on the BIM library. Additionally, the interface providing unit can provide an interface that allows the user to select the target capacity of the energy storage system to be installed and the target load of the battery rack where the battery module is installed.

[0046] Through the interface providing unit (300), the battery module specifications, target capacity, and target load can be entered and the starting point selected.

[0047] When inputting battery module specifications, the specifications of the latest battery module are stored in the library storage unit (100), so a battery module stored in the library can be selected.

[0048] The interface providing unit (300) provides a plan view of the part where the battery rack is to be installed based on the BIM library, and the user can select a starting point with a mouse.

[0049] The above modeling unit (400) calculates the number of battery modules required for the energy storage system and configures the battery rack. The width, length, and height of the battery rack can be calculated based on a selected starting point and modeled in a 3D form.

[0050] When a user selects a battery module from a specific manufacturer, inputs a target capacity, and specifies a starting point and a placement range in a planar view, the modeling unit (400) calculates the number of battery racks required to achieve the target capacity based on the selected battery module, and performs 3D modeling by continuously placing the products within the specified range according to the calculated quantity.

[0051] The above positioning interface (320) can provide graphics that the user can select by dragging with a mouse.

[0052] When a location is selected by the method described above, the modeling unit (400) can model the energy storage system and display the battery rack. FIG. 9 shows an example of a modeling result according to an embodiment of the present invention.

[0053] The above modeling unit (400) can calculate the total weight of the battery rack containing the battery and calculate the load applied per unit area. The modeling unit (400) calculates the load per unit area based on the total weight and installation area information of the placed battery rack and examines whether the load per unit area exceeds the target load.

[0054] If the load per unit area is appropriately below the target load, a report indicating that the layout is structurally stable can be automatically generated and printed.

[0055] Conversely, if the load per unit area exceeds the target load, modeling is performed again. At this time, the interface providing unit (300) can provide an interface for inputting lighter battery specifications.

[0056] The user can choose to select the lighter battery specification or not. If the new battery specification is not selected, the model can be remodeled by increasing the area of ​​the battery rack.

[0058] Additionally, the modeling unit (400) can calculate the expected lifespan of the battery module and the battery replacement time based on the specifications of the battery module and the average daily power consumption of the building. Specifically, the modeling unit (400) can calculate the expected lifespan of the battery module and estimate the battery replacement time by calculating the number of charge / discharge cycles based on the specifications of the battery module.

[0059] The average daily power consumption of the building can be stored in a BIM library, and if it is not stored in a BIM library, it can be entered by a user. At this time, the interface providing unit (400) can provide an interface for entering the average daily power consumption of the building.

[0060] With the above configuration, the energy storage system modeling platform can provide the latest library to the user terminal, and the user terminal can perform modeling using the latest library.

[0061] When modeling, not only is the quantity of battery modules or the number of battery racks calculated, but the location where the battery racks are installed is provided in a 3D form, and the load exerted by the battery racks on the building can be calculated.

[0062] In addition, the battery module can be managed efficiently by predicting its replacement timing.

[0063] The above report writing unit (500) can write the modeling results in the form of a report. That is, it can write details regarding battery specifications, battery rack placement, battery rack weight, and the expected time for battery replacement.

[0064] Various technical requirements related to the installation and operation of the ESS system (operating conditions, electrical protection schemes, placement standards, fire safety standards, etc.) can be organized in the form of a library, and an interface can be provided to input these items as attribute values.

[0065] The report generation unit (500) includes a function to automatically generate a report by determining the appropriateness (e.g., appropriate / inappropriate) of each item based on the input attribute information.

[0066] At this time, the attribute values ​​may include charging rate limit conditions, whether an abnormal sign detection and cutoff system is configured, the placement location of the emergency stop device, whether leakage current monitoring is recorded, whether the ESS room is fire-compartmented, whether an access control device is installed, and whether the firefighting equipment (NFSC 607 standard) is configured as an exhaust system. Each item is automatically evaluated by comparing it with a pre-set standard, and the results are output in the form of a design review checklist and a report.

[0067] The report writing department may include the following items.
