Description

Method and system for integrated operation modeling of multiple energy objects for eco-friendly, carbon-free energy-based urban planning.

[0001] The present invention relates to a method and system for modeling the integrated operation of multiple energy objects for urban planning based on eco-friendly, carbon-free energy, and more particularly, to a system model in which energy objects can be integrated and operated, particularly a system model in which integrated operation is possible by linking small modular reactors (SMRs) and renewable energy, and a modeling method and system in which the energy flow on the system model is visualized so that a user can intuitively understand and manage the energy flow.

[0002] Modern energy systems operate in a complex manner, integrating various forms of energy, including electricity, heat, and hydrogen. These diverse forms of energy are produced and consumed across different sectors, and efficiently managing the energy flow between them is crucial. Traditionally, energy has been managed in independent systems, often without considering the interactions between various energy forms, such as electricity, heat, and hydrogen. This hinders energy efficiency and leads to wasteful energy resources.

[0003] Meanwhile, sector coupling is an approach to addressing these issues. It is a technology that maximizes the efficiency of energy systems by integrating and managing the interactions between various energy sources, including electricity, heat, and hydrogen. This optimizes energy production and consumption and effectively manages the volatility of renewable energy.

[0004] However, sector coupling is a technology that operates various types of energy in an integrated manner. However, existing energy control systems, which are mainly designed around a single type of energy, have limitations in building a model that can visually understand the energy flow of urban design in which multiple types of energy interact and operate based on sector coupling.

[0005] Therefore, there is a need for a method and system that visualizes the energy flow of urban designs built on sector coupling so that users can intuitively understand it.

[0006] The purpose of the present invention is to provide a method and system for visualizing energy progress on a multi-energy object in which various types of energy are operated, thereby enabling a user to intuitively understand and manage the energy flow.

[0007] Furthermore, the present invention aims to minimize carbon emissions through efficient energy management, with a particular goal of dramatically reducing carbon emissions through sector coupling. For example, in transportation, the use of electric vehicles can be replaced with electricity to reduce carbon emissions. In heating and cooling, the use of heat pumps can be replaced with electricity to dramatically reduce carbon emissions. Furthermore, in this process, reducing carbon emissions may take precedence over improving energy efficiency.

[0008] The technical problems of the present invention are not limited to the technical problems mentioned above, and other technical problems not mentioned will be clearly understood by those skilled in the art from the description below.

[0009] The present invention is to solve the above technical problem, and a method for visualizing energy flow between a plurality of energy objects that are integratedly operated based on sector coupling according to the present invention comprises: (a) a first step of receiving a plurality of energy objects, wherein the energy objects are objects that can produce and supply energy or consume supplied energy, and creating and displaying objects for the energy objects; (b) after the first step, the system analyzes the relationships between the energy objects input in the first step, creates an energy system model, which is a model that defines the relationships between the energy objects by connecting the energy objects to each node, and creates and displays the energy system model including objects for the energy objects and graphics for the nodes; (c) a third step of receiving additions, changes, and deletions for energy objects or nodes in the energy system model, and creates and displays a changed energy system model; (d) a fourth step of generating energy operation scenario data, which is data for a scenario in which each energy object of the energy system model produces or consumes energy and supplies energy through nodes connected between energy objects; And (e) a fifth step of generating and displaying a simulation image in which the energy system model performs the energy operation scenario based on the energy operation scenario data;

[0010] In addition, in the above method, the energy object may be classified by type as a production object or a demand object, the production object may be classified by type as a controllable production object or a variable production object, and the demand object may be classified by type as a controllable demand object or a variable demand object.

[0011] In addition, in the above method, one energy object can be characterized in that it can produce one or more types of energy among hydrogen, heat, and electricity by consuming one or more types of energy among hydrogen, heat, and electricity, and can consume one or more types of energy among hydrogen, heat, and electricity supplied from another energy object.

[0012] In addition, in the above method, the first step may be characterized by receiving a plurality of energy objects including at least one controllable generation object or controllable demand object.

[0013] In addition, in the method, the first step may be characterized by receiving a plurality of energy objects, including at least one energy conversion object, wherein the energy conversion object is an energy object that consumes electrical energy to produce one or more types of energy other than electricity, and is classified as a controllable production object.

[0014] The present invention has the effect of visualizing the energy progress on a multi-energy object in which various types of energy are operated, thereby enabling a user to intuitively understand and manage the energy flow.

[0015] In addition, according to the present invention, there is an effect of drastically reducing carbon emissions, and in particular, one of the purposes is to drastically reduce carbon generation through sector coupling.

[0016] The effects of the present invention are not limited to the effects mentioned above, and other effects not mentioned will be clearly understood by those skilled in the art from the description below.

The advantages and features of the present invention, and methods for achieving them, will become clearer with reference to the embodiments described in detail below together with the attached drawings. However, the present invention is not limited to the embodiments disclosed below and may be implemented in various different forms. These embodiments are provided only to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the invention, and the present invention is defined solely by the scope of the claims.

Unless otherwise defined, all terms (including technical and scientific terms) used herein may be used in their common sense to those of ordinary skill in the art to which the present invention pertains.

[0024] Figure 1 is a drawing showing the overall configuration included in a sector coupling-based multi-energy object integrated operation modeling system (100, hereinafter referred to as “system”).

[0025] However, this is only a preferred embodiment for achieving the purpose of the present invention, and some components may be added or deleted as needed, and the role performed by one component may be performed by another component as well.

[0026] Referring to FIG. 1, a sector coupling-based multi-energy object integrated operation modeling system (100) according to one embodiment of the present invention may include a processor (10), a network interface (20), a memory (30), a storage (40), and a data bus (50) connecting them, and it will be understood that it may further include additional components required to achieve the purpose of the present invention.

[0027] The processor (10) controls the overall operation of each component. The processor (10) may be any one of a CPU (Central Processing Unit), an MPU (Micro Processor Unit), an MCU (Micro Controller Unit), or a processor of a type widely known in the technical field to which the present invention pertains, and may be implemented as an artificial intelligence model processor, such as a machine learning model processor or a deep learning model processor. In addition, the processor (10) may perform operations for at least one application or program for performing a sector coupling-based multi-energy object integrated operation modeling method according to an embodiment of the present invention.

[0028] The network interface (20) supports wired and wireless communication of the system (100) according to one embodiment of the present invention, and may also support other known communication methods. Accordingly, the network interface (20) may be configured to include a corresponding communication module.

[0029] The memory (30) stores various types of information, commands, and / or information, and can load one or more computer programs (41) from the storage (40) to perform a sector coupling-based multi-energy object integrated operation modeling method according to an embodiment of the present invention. In FIG. 1, RAM is illustrated as one of the memories (30), but it goes without saying that various storage media can be used as the memory (30).

[0030] Storage (40) can non-temporarily store one or more computer programs (41) and large-capacity network information (42). This storage (40) can be any one of non-volatile memory such as Read Only Memory (ROM), Erasable Programmable ROM (EPROM), Electrically Erasable Programmable ROM (EEPROM), flash memory, a hard disk, a removable disk, or any type of computer-readable recording medium widely known in the art to which the present invention pertains.

[0031] A computer program (41) can be loaded into a memory (30) and executes (a) a first step of receiving a plurality of energy objects and generating and displaying graphics for the energy objects, (b) a second step of analyzing the relationships between the energy objects and connecting the energy objects to each node to generate an energy system model, and generating and displaying graphics for the energy system model including graphics for the energy objects and graphics for the nodes, (c) a third step of receiving additions, changes, and deletions for energy objects or nodes for the energy system model, and generating and displaying graphics for the changed energy system model, (d) a fourth step of generating energy operation scenario data, which is data for a scenario in which each energy object of the energy system model produces or consumes energy and supplies energy through nodes connected between energy objects, and (e) a fifth step of generating and displaying a simulation image in which the energy system model performs the energy operation scenario based on the energy operation scenario data.

[0032] The operations performed by the computer program (41) briefly mentioned above can be considered as one function of the computer program (41). Meanwhile, a more detailed description of the operations performed by the computer program (41) described above will be provided later in the description of the method for integrated operation modeling of multiple energy objects based on sector coupling according to an embodiment of the present invention.

[0033] The data bus (50) serves as a path for transferring commands and / or information between the processor (10), network interface (20), memory (30), and storage (40) described above.

[0034] The system (100) according to one embodiment of the present invention, which has been briefly described above, may be in the form of an independent device or a component of another device, and here, the device may be any device that has a CPU corresponding to the processor (10), such as a server that supports wired and wireless communication, is installed and has a network function, and is equipped with a means for a user to input settings, or is connected to an external device through which a user can input settings, and into which user input or settings for performing each step of a sector coupling-based multi-energy object integrated operation modeling method can be input.

[0035] In addition, the system (100) according to one embodiment of the present invention should be viewed as a concept that includes software / applications for implementing the process of the sector coupling-based multi-energy object integrated operation modeling method described below, regardless of hardware, provided that such software / applications are stored in specific physical means / recording media, etc.

[0036] Hereinafter, with reference to FIG. 2, a method for modeling multi-energy object integration operation based on sector coupling according to terrain that can be implemented by the above-described system (100) will be described.

[0037] However, this is only a preferred embodiment for achieving the purpose of the present invention, and it is obvious that some steps may be added or deleted as needed, and one step may be included in another step and performed.

[0038] In addition, each step is assumed to be performed by a server in the form of an implementation of the system (100) according to an embodiment of the present invention, and it is assumed that the settings or user inputs inputted into the system (100) in each step are performed by a user terminal that is connected to the system (100) by wire or wirelessly and has a display to provide a user interface. Here, the user terminal may be any device having a display and network function, more specifically, a smartphone, a smart watch, smart glasses, a laptop computer, a tablet computer, a PDA, a PDP, a PMP, etc., but the following description will be continued on the assumption that the user terminal is a PC.

[0039] FIG. 2 is a flowchart showing representative steps of a sector coupling-based multi-energy object integrated operation modeling method according to one embodiment of the present invention.

[0040] Referring to FIG. 2, first, the system (100) receives a plurality of energy objects, graphically generates objects for the energy objects, and displays them (S100), which is referred to as the first step.

[0041] Here, an energy object refers to a sector that produces or consumes energy in an energy system model, or may refer to an energy producer or consumer included in that sector. For example, an energy object may refer to a group (sector) of entities that produce one or more types of energy among hydrogen, heat, and electricity by consuming one or more types of energy among hydrogen, heat, and electricity, or individual entities within that group, or may refer to a group (sector) of entities that consume one or more types of energy among hydrogen, heat, and electricity supplied from another energy entity, or individual entities within that group.

[0042] Meanwhile, in one embodiment of the present invention, an energy object whose energy production is greater than its energy consumption based on electric energy is classified as a production object, and an object whose energy consumption is greater than its energy production is classified as a demand object. In addition, in one embodiment of the present invention, among production objects, an object capable of controlling the amount of energy produced is classified as a controllable production object, an object capable of producing energy based on an external environment or external factors and thus unable to control the amount of energy produced is classified as a variable production object, and among demand objects, an object capable of controlling the amount of energy demand is classified as a controllable demand object, and an object whose energy demand is determined by an external environment or external factors and thus unable to control the amount of energy demand is classified as a variable demand object.

[0043] Specifically, as described above, in one embodiment of the present invention, in order to intuitively visualize (or model) the energy demand and supply flow of multiple objects for multiple types of energy, energy objects operated based on multiple types of energy are converted to production and demand based on one type of energy, and each energy object is graphically displayed as objects with different volumes according to the amount of energy so that a user can intuitively understand the energy demand and supply of multiple objects.

[0044] In one embodiment of the present invention, when a specific energy object uses electrical energy to produce any type of energy other than electrical energy, the unit amount of electrical energy required to produce the arbitrary type of energy may be converted into an amount of electrical energy demand, thereby calculating the demand or production amount for the arbitrary energy.

[0045] In addition, in one embodiment of the present invention, when a specific energy object uses any type of energy other than electrical energy, and the arbitrary energy can be produced by consuming electrical energy by the specific energy object or another energy object connected to the specific energy object, the demand or production of the arbitrary energy can be calculated by converting the unit amount of electrical energy required for the specific energy object or the other energy object to produce the arbitrary type of energy into the energy demand of the specific energy object.

[0046] For example, a controllable production object can be a Small Modular Reactor (SMR), a variable production object can be a solar power generator, a wind power generator, etc., a controllable demand object can be a heat pump (which generates heat using electrical energy; the heat generation amount decreases as the electrical energy usage decreases and the heat generation amount increases as the electrical energy usage increases), a water electrolysis system (which produces hydrogen by electrolyzing water using electrical energy; the hydrogen production amount decreases as the electrical energy usage decreases and the hydrogen production amount increases as the electrical energy usage increases), a hydrogen fuel cell (which produces and stores hydrogen fuel using electrical energy), etc., and a variable demand object can be an industrial complex, a residential complex, an agricultural complex, etc. A controllable demand object can produce other energy (or energy source) by consuming electrical energy, and a controllable demand object is characterized by being able to adjust the consumption of electrical energy by controlling how much other energy is produced. Meanwhile, variable demand objects are characterized by the fact that the amount of electric energy consumed fluctuates only according to the usage conditions of general electric consumers in industrial complexes, residential complexes, agricultural complexes, etc., and that the amount of electric energy consumed cannot be adjusted.

[0047] Meanwhile, each energy object may include object data, which is data including information about its name, type, kind, identification number, demand, and type of energy produced, etc. For example, the object data may include information about the type of energy produced by the energy object, the type of energy consumed by the energy object, the energy production and consumption pattern of the energy object, the maximum production per unit time of the energy object, the minimum production per unit time of the energy object, the maximum energy consumption per unit time of the energy object, the minimum energy consumption per unit time of the energy object, the average energy production and consumption per unit time of the energy object, and the amount of energy loss per unit time.

[0048] Here, the type of energy object refers to a category distinguished according to the method and purpose of each object producing, converting, storing, or consuming energy. More specifically, in one embodiment of the present invention, the system has pre-stored types for one or more types of energy objects, and the types of energy objects stored in the system may be “nuclear power generation,” “wind power generation,” “solar power generation,” “fuel cell,” “agricultural complex,” “industrial complex,” “building,” “house,” etc. In addition, the type of each energy object may be preset in the object data of the energy object, and in the case of an energy object for which the object type is not specified, one of the types pre-stored in the system may be specified by a user input or the system. For example, a Small Modular Reactor (SMR) may be a controlled production object, and the type of the energy object may be nuclear power generation.

[0049] Meanwhile, in the first step to the second step described below according to an embodiment of the present invention, the object for the demand object may be displayed in a block shape whose volume is set in proportion to the average value of the electric energy demand per unit time of the corresponding energy object, and the object for the production object may be displayed in a block shape whose volume is set in proportion to the average value of the electric energy production per unit time of the corresponding energy object.

[0050] After the first step, the system (100) analyzes the relationship between energy objects input in the first step, creates an energy system model which is a model that defines the relationship between energy objects by connecting the energy objects to each node, and creates and displays the energy system model including graphics (objects) for the energy objects and graphics for the nodes (S200), which is referred to as the second step.

[0051] Specifically, in the second step, the system (100) can search for energy objects whose types of energy produced and types of energy consumed correspond to each other and connect them as nodes.

[0052] In addition, each node may include node data, which is data necessary to generate an energy operation scenario to be described later by performing an analysis on energy flow between object data, and as an example, the node data may include at least one or more of information on the type of energy supplied between connected energy objects, the direction in which energy is supplied, the minimum and maximum amounts of energy that can be supplied per unit time, the type of energy supplied, and the energy loss coefficient when supplying energy.

[0053] After the second step, the system (100) can receive input for addition, change, and deletion of energy objects or nodes for the energy system model, and generate and display graphics for the changed energy system model (S300), which is referred to as the third step.

[0054] To be more specific, the third step is a process step of changing / adding / deleting nodes automatically set and connected by the system (100) in the second step on the generated energy system model, or changing / adding / deleting energy objects.

[0055] For example, in the third step, the user may delete a node between two energy objects connected by a system (100) that are theoretically capable of transmitting and receiving energy, if the energy supply between the two energy objects is actually impossible due to external factors or if the amount of energy loss during the energy supply between the two energy objects is so great that the connection is inefficient.

[0056] As another example, a user may create an energy system model to manage actual energy facilities, and when an energy facility to be actually managed is added, the user may additionally input and add an energy object to reflect this in the energy system model.

[0057] Meanwhile, in one embodiment of the present invention, if the user determines that no additional changes to the energy system model generated in the second step are necessary, it is also possible to omit the third step described above.

[0058] After the third step, the system (100) generates energy operation scenario data, which is data for a scenario in which each energy object of the energy system model produces or consumes energy and supplies energy through nodes connected between energy objects (S400), and this is referred to as the fourth step.

[0059] Specifically, in the fourth step, the system (100) can generate energy operation scenario data including information on energy production and demand of each energy object and information on energy supply between energy objects on an energy system model for a specific period of time based on object data for each energy object and node data for each node. Meanwhile, the specific period of time here means a period during which the energy production and consumption patterns of each energy object can be sufficiently repeated so that the energy progress flow according to the characteristics of each energy object can be reflected in the energy operation scenario data.

[0060] To be more specific, as explained above, in the present invention, energy objects are classified into controlled production objects, controlled demand objects, variable production objects, or variable demand objects depending on whether production or demand can be controlled. Accordingly, the energy operation scenario can be understood as a scenario that allows for integrated management of energy of all energy objects in the energy system model by adjusting the production or demand of a controlled production object or a controlled demand object for each time zone in response to a variable demand object.

[0061] Accordingly, if there are no controllable production objects or controllable demand objects in the energy system model, it is impossible to produce an energy operation scenario that adjusts the production or demand amount of the controllable production object or controllable demand object for each time zone to correspond to the variable demand object. Therefore, in the first step according to one embodiment of the present invention, the system (100) receives a plurality of energy objects including at least one controllable production object or controllable demand object.

[0062] In addition, in the first step according to another embodiment of the present invention, the system (100) receives a plurality of energy objects, including at least one energy object designated as a type of nuclear power generation, more precisely, a Small Modular Reactor (SMR). As described above, since the energy system model must include at least one controllable production object or controllable demand object to generate an energy operation scenario that controls the production or demand amount of energy in response to a variable demand object, this is a configuration for generating an energy operation scenario in which energy can be supplied more stably to a demand object by having the energy system model include at least one energy object of the nuclear power generation type that has a relatively higher energy production amount per unit time compared to other types of energy objects.

[0063] In addition, in the first step according to another embodiment of the present invention, the system (100) receives a plurality of energy objects, including at least one energy conversion object. Here, the energy conversion object is an energy object that consumes electric energy to produce one or more types of energy other than electricity, and is an energy object classified as a controllable production object. For example, the energy conversion object may be a heat pump that consumes electric energy to produce heat, or a water electrolysis system that consumes electric energy to produce hydrogen, etc. Specifically, as described above, the system (100) of the present invention distinguishes between demand objects and production objects based on electric energy, and defines an energy conversion object that consumes electric energy to produce energy other than electricity as a demand object. Meanwhile, the above-described embodiment is a configuration for generating an energy operation scenario so that the electric energy generated in the energy system model can be stored more efficiently by including an energy conversion object that can convert electric energy into heat or hydrogen, etc. and store it in the energy system model.

[0064] Meanwhile, in one embodiment of the present invention, the system (100) can generate energy operation scenario data in the fourth step, where the energy operation scenario includes one or more conditions or criteria.

[0065] For example, the system (100) may generate energy operation scenario data based on the first condition that no energy object in which the energy demand per unit time is greater than the energy supply per hour occurs in the entire time zone of the energy operation scenario data, and the second condition that the sum of the energy production per unit time of the energy objects is always greater than the sum of the energy demand per unit time of the energy objects and the value of the reserve energy set by the system (100) or the user, and the first and second criteria are satisfied, and the total loss of electric energy is the lowest.

[0066] Meanwhile, in the fourth step described above, the system (100) may use artificial intelligence or an artificial neural network to analyze energy object data and node data on the energy system model and generate an energy operation scenario that satisfies specific conditions or criteria according to an embodiment. Here, there is no limitation on the type of artificial intelligence or an artificial neural network, and any type of known network model may be used.

[0067] After the fourth step, the system (100) generates and displays a simulation image in which the energy model performs the energy operation scenario based on the energy operation scenario data (S500), and this is referred to as the fifth step.

[0068] Additionally, in the fifth step, the graphic for the production object is formed as a block shape whose volume is set in proportion to the electric energy production per unit time of the object in the time of the ongoing simulation, and the graphic for the demand object is formed as a block shape whose volume is set in proportion to the electric energy demand per unit time of the object in the time of the ongoing simulation.

[0069] In addition, in the fifth step according to one embodiment of the present invention, if there is a specific energy object that demands or produces any type of energy other than electric energy in the energy system model, the unit amount of electric energy for producing the energy is converted into the demand amount of electric energy, and the demand or production amount for the arbitrary energy is calculated to set the volume for the specific energy object.

[0070] Meanwhile, in one embodiment of the present invention, after step 5, step 3 may be performed again, thereby repeating steps 3 through 5. This configuration allows the user to reconfigure the energy system model accordingly after confirming the energy operation scenario in step 5.

[0071] Hereinafter, with reference to FIGS. 3 to 6, actions and effects that can be implemented according to each step of the above-described sector coupling-based multi-energy object integrated operation modeling method will be described as examples.

[0072] For reference, each step of FIG. 2 can be executed upon receiving user input through a separate user interface provided to the user. As mentioned above, each energy object or energy sector can be displayed in the form of a block. As can be seen in FIGS. 3 to 6, block-shaped objects are inserted and arranged in the supply channel and demand channel to form the entire energy system model. In the present invention, a user interface is provided to enable such insertion and arrangement, thereby supporting a user to intuitively design the city's energy supply channel and energy demand channel when designing an arbitrary city, especially when planning an eco-friendly, carbon-free energy-based city.

[0073] In addition, the term "sector coupling" used in this detailed description refers to an energy management method proposed to comprehensively manage electric energy by utilizing the mutually convertible nature of various energy sources such as electricity, heat, and hydrogen, and this sector coupling can be easily explained, in particular, by the object indicated by the reference numeral 3 in FIGS. 3 to 6. The reference numeral 3 in FIGS. 3 to 6 represents a single object, together with the electricity block (Electricity), which is arranged in the demand channel and includes a heat pump (Heat) block that enables heating and cooling using electric energy, and a water electrolysis system (Hydrogen) block that produces hydrogen using electric energy. In order to facilitate understanding of the invention, the above objects will be referred to as coupling objects, and the above coupling objects may include not only heat pumps and water electrolysis systems, but also all types of energy objects that can generate other types of energy using electric energy, such as desalination systems and electric vehicles, i.e., blocks corresponding to the energy conversion objects mentioned above. The above coupling object can be composed of energy conversion objects that produce or consume mutually convertible energy, and such coupling objects can be understood as an important component for improving system efficiency through sector coupling between different energies. For example, a heat pump can generate heat using electrical energy, and when the demand for electrical energy in a city suddenly increases, the operation of the heat pump can be drastically reduced to quickly reduce the demand for electrical energy. In this case, the important fact is that thermal energy has different energy characteristics from electrical energy, and due to these different energy characteristics, the coupling object can flexibly balance the demand and supply sides of electrical energy within the overall energy system model.For an easier example, even if the operation of a heat pump is drastically reduced to rapidly reduce the demand for electric energy, since thermal energy has a long-term fluctuation characteristic (even if the heating in a specific space is stopped, the temperature within the space does not drop sharply but rather gradually), the balancing between the demand side and the supply side of electric energy can be performed quickly compared to the time it takes for the remaining thermal energy to be consumed. It is precisely because of this difference in the characteristics of the energies that the sector coupling in the coupling object enables flexible balancing between the demand side and the supply side within the entire energy system model. That is, the method for modeling the integrated operation of multiple energy objects according to the present invention is characterized by including coupling objects capable of sector coupling in the demand side of the energy system model as essential, thereby utilizing the differences in the energy characteristics of different energies, more precisely, the differences in the variability that energy has on the entire system, to enable flexible balancing between the demand side and the supply side of electric energy.

[0074] Referring back to FIG. 3, in the first step, the user can input multiple energy objects into the system, including at least one energy conversion object and at least one energy object designated as a type of nuclear power generation. At this time, the energy objects input by the user can be arranged in the demand channel area (demand end) or the production channel area (supply end) according to the type classified as a production object or a demand object on the graphic generated by the system (100). As mentioned above, the energy objects can each be displayed as block-shaped objects. For example, objects corresponding to multiple energy objects can be selected and listed on the user interface, and the user can drag an object corresponding to a specific energy object and arrange it on the demand channel area or the production channel area. In this process, the user interface can provide various graphic effects to enable the user to easily match the energy supply and demand of the supply end and the demand end. For example, if a user places a 200MW SMR object in the production channel area (supply end), a hexahedron indicating that a 200MW demand object can be placed is displayed in the demand channel area (demand end), thereby assisting the user in finding objects that can fill the 200MW hexahedron. At this time, if the user selects a demand object that can consume 50MW of electrical energy and drags the corresponding object into the hexahedron, the hexahedron is now expressed with a graphic effect indicating that it can consume 150MW of surplus energy, thereby guiding the user to select the remaining demand objects.

[0075] Referring to FIG. 4, thereafter, in the second step, the system (100) can analyze the relationship between the energy objects to generate an energy system model, and the energy objects can be connected to each node that is linearly displayed according to the relationship between each energy object on the graphic displayed by the system (100). These nodes can be utilized in the process of designing an arbitrary city-wide energy system model to determine that a specific demand object can only receive electric energy from a specific production object, or can be utilized in determining that a specific demand object can only receive electric energy from a plurality of designated production objects. Meanwhile, at this time, the coupling object (3) described above is preferably connected to all production objects (SMR, wind power generation system, solar power generation system, tidal power generation system, etc.) as nodes, thereby increasing the stability of energy supply and demand in the entire energy system model.

[0076] Referring to FIG. 5, in the third step, the user can add, change, or delete energy objects and nodes, and the system (100) can generate graphics reflecting the additions, changes, or deletions made by the user and display them.

[0077] In the fourth step, the system (100) generates an energy operation scenario for the energy system model set by the user.

[0078] Referring to FIG. 6, in the fifth step, the user can visually grasp the flow of energy through the volume of each energy object that changes as the energy operation scenario progresses.

[0079] Meanwhile, the process of the sector coupling-based multi-energy object integrated operation modeling method according to one embodiment of the present invention described above is only a preferred embodiment for achieving the purpose of the present invention, and some steps may be added or deleted as needed, and one step may be included in another step and performed.

[0080] Although embodiments of the present invention have been described with reference to the attached drawings, those skilled in the art will appreciate that the present invention can be implemented in other specific forms without altering the technical concept or essential features thereof. Therefore, the embodiments described above should be understood to be illustrative in all respects and not restrictive.
