Description

Integrated power operation system and method for public facilities and electric vehicles

[0001] The present invention relates to a power integration operation system and method for public facilities and electric vehicles.

[0002]

[0003] Smart distribution panels are emerging as useful devices for optimizing and stabilizing power consumption and generation.

[0004] Looking at its application areas, various distributed energy resources, such as solar power, wind power, and energy storage systems, can be integrated into smart distribution panels to ensure a stable power supply and optimize energy consumption. Furthermore, IoT technology enables the visualization of power data, enabling data analysis to improve power grid efficiency.

[0005] Applying these smart technologies to distribution panels has the advantage of optimizing power consumption and extending the life of equipment.

[0006] Meanwhile, with the recent increase in electric vehicles, efficient power management and improved safety of electric vehicle charging infrastructure are emerging as important issues for expanding electric vehicle charging infrastructure.

[0007] As the spread of electric vehicles increases, the need to actively control the power supplied to vehicles to ensure grid stability is increasing.

[0008]

[0009] The technical problem to be solved by the present invention is to provide an operating system and method for load power of a public facility and charging power for electric vehicles, which can stabilize the power grid of the facility by mutually adjusting the required power between the load power of the public facility and the charging power for electric vehicles.

[0010]

[0011] In order to solve the above technical problem, an integrated power operation method for a public facility and an electric vehicle according to an embodiment of the present invention may include a step of setting power transaction conditions; a step of predicting the power demand of public facility loads and the charging demand of electric vehicles, respectively; a step of operating a power distribution operation to meet the required power by trading the public facility load power used by a first user and the charging power of an electric vehicle used by a second user; and a step of determining whether to add or deduct points for the first user and the second user related to the transaction.

[0012] In one embodiment of the present invention, the step of setting the power trading conditions for the first user includes the steps of: determining essential loads and non-essential loads; determining priorities among the non-essential loads; and determining trading conditions for each load power; wherein the trading conditions for each load power may be any one of the following conditions: unconditional for non-essential loads, time-dependent for essential loads, time-dependent for non-essential loads, and conditional for relationships with other loads.

[0013] In one embodiment of the present invention, the step of setting the power transaction conditions for the second user includes the step of receiving charging request information; and the step of determining charging power transaction conditions; wherein the charging power transaction conditions may be any one of conditions related to a charging amount and conditions related to a charging time.

[0014] In one embodiment of the present invention, the power distribution operation step includes a step of determining whether the power demand of the common building load exceeds or is predicted to exceed the target power; a step of checking the charging state of the energy storage device; and a step of selecting an additional power supply source according to the charging state of the energy storage device and the required power amount; wherein the additional power supply source may be at least one of the charging power and the power stored in the energy storage device.

[0015] In one embodiment of the present invention, if the additional supply source is charging power, the step of compensating for the charging power may be further included.

[0016] In one embodiment of the present invention, the power distribution operation step includes a step of determining whether the power demand of the charging power exceeds or is predicted to exceed the allowable power; a step of checking the charging state of the energy storage device; and a step of selecting an additional power supply source according to the charging state of the energy storage device and the required power amount; wherein the additional power supply source may be at least one of the load power and the power stored in the energy storage device.

[0017] In one embodiment of the present invention, the method may further include: a step of determining the necessity of power distribution despite the power distribution operation step; a step of requesting power distribution to at least one of a first user terminal and a second user terminal; a step of determining whether to cooperate with the power distribution request; and a step of generating point information for a user who cooperated with the power distribution request.

[0018] In one embodiment of the present invention, if the power of the load used by the first user decreases within a preset time after the transmission of the power distribution request, the first user can be identified as the first user who cooperated with the power distribution request.

[0019] In one embodiment of the present invention, after transmitting the distribution request, the average usage amount of the first user over a certain period of time is compared with the past usage amount of the same user over the same time period before the distribution request, the current usage amount of another user, or the past usage amount of another user over the same time period before the distribution request. If the usage amount is lower than a preset reference value, the first user can be identified as having cooperated with the power distribution request.

[0020] In order to solve the above technical problem, an integrated power operation system for a common facility and an electric vehicle according to an embodiment of the present invention transmits and receives information to and controls an energy storage device, a load management system, and an electric vehicle charging system, respectively, and operates the power for the common facility and the electric vehicle in an integrated manner, wherein the operation system sets power transaction conditions, predicts the power demand of common facility loads and the charging demand of electric vehicles, respectively, and trades the common facility load power used by a first user and the charging power of an electric vehicle used by a second user to meet the required power, and can determine whether to add or deduct points for the first user and the second user related to the transaction.

[0021]

[0022] The present invention has the effect of stabilizing the power grid of a facility by mutually adjusting the required power between the load power of a public facility and the charging power for electric vehicles, and inducing participation by providing appropriate compensation to users who participated in the adjustment.

[0033] The present invention is susceptible to various modifications and embodiments. Specific embodiments are illustrated in the drawings and described in detail in the detailed description. However, this is not intended to limit the present invention to specific embodiments, but rather to encompass all modifications, equivalents, and alternatives falling within the spirit and technical scope of the present invention.

[0034] In describing the present invention, if it is determined that a detailed description of a related known technology may obscure the gist of the present invention, the detailed description is omitted.

[0035] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings.

[0036]

[0037] Figure 1 illustrates an integrated power operation system (100) for public facilities and electric vehicles. Hereinafter, the integrated power operation system (100) for public facilities and electric vehicles is also referred to as an 'operation system (100)'.

[0038] Referring to FIG. 1, the operating system (100) is connected to an energy storage device (200), a load management system (300), and an electric vehicle charging system (400) via a wired / wireless network to transmit and receive information and control them.

[0039] The operating system (100) may be either a server or a cloud server with a built-in processor for information processing, may include multiple physically or logically separated terminals for providing information processing, and may be provided in a form in which it is distributed and installed in multiple locations or uses a cloud service for storing and processing information.

[0040] Although not shown in the drawing, the operating system (100) may include a protocol integration management unit that integrates and manages different protocols between the load management system (300) and the electric vehicle charging system (400).

[0041] An energy storage system (200) stores generated or supplied electricity for use when needed. For buildings, the system may require an energy storage system equivalent to 5% of the contracted power.

[0042] The energy storage device (200) can be connected to both the load management system (300) and the electric vehicle charging system (400) to supply power to both or selectively.

[0043] The energy storage device (200) is not necessarily an essential component in the embodiments of the present invention. However, if the energy storage device (200) is configured, it can more advantageously respond to various power demand situations.

[0044] The load management system (300) may include a smart distribution panel (310), a communication unit (320), a power meter (330), a control unit (340), and a load monitoring device (350) (see FIG. 3).

[0045] The smart distribution panel (310) can distribute the power used for each load.

[0046] The communication unit (320) can report the amount of power measured for each load to the operating system (100) and receive control information from the operating system (100) and provide it to the control unit (340).

[0047] The power meter (330) can collect total power usage information of a group consisting of multiple loads and provide it to the control unit (340).

[0048] The load monitoring device (350) can collect power information used by each load (e.g., refrigerator, washing machine, computer, etc.) and provide it to the control unit (340). All usage information for each load can be provided to the operating system (100).

[0049] A load monitoring device (350) may include an E-tag provided to a circuit breaker that collects and transmits data regarding the circuit breaker's operating status or the amount of power measured by the circuit breaker. The E-tag may detect the circuit breaker's operating status and generate data thereon. The E-tag may collect data regarding the amount of power measured and transmit the data to an external device.

[0050] This tag can be provided to the circuit breaker. This tag can detect the operating status of the circuit breaker and generate data about it. It can also collect data on the amount of power measured by the circuit breaker. Furthermore, this collected data can be transmitted externally. This tag...

[0051] Although not shown in the drawing, the electric vehicle charging system (400) may include a main distribution unit, a sub-distribution unit, a busway, and a charger.

[0052] The main distribution unit may include a leakage circuit breaker, a molded case circuit breaker (MCCB), a power meter, a gateway, and a communications unit.

[0053] The main distribution unit is the main channel for transmitted power to a collection of power demands such as building parking lots, and can play a role in distribution and management within the allowable range of power amount.

[0054] The gateway supports communication with power supply lines and electric vehicle charging lines that allow different protocols and may have built-in distribution algorithms.

[0055] The main distribution unit can set and provide the allowable charging current to the sub-distribution units registered through the gateway.

[0056] The sub-distribution unit can be coupled to the busway.

[0057] The sub-distribution unit can be connected to the main distribution unit and the charger, respectively.

[0058] The sub-distribution unit can use or redistribute power distributed from the main distribution unit.

[0059] The sub-distribution unit can be connected to multiple chargers.

[0060] The distribution unit may include a circuit breaker, a communication unit, a power meter, a miniature circuit breaker (MCB), and a magnetic contactor (MC).

[0061] The charger may include a cable that can be connected to a sub-distribution unit and an EV vehicle charging terminal.

[0062] Busway: It has a similar role to bus duct and can refer to a large-scale bus duct that connects between the generator and transformer terminals.

[0063] The busway can be formed as an extension from the main distribution unit and can be installed mainly close to the ceiling side.

[0064] The busway can be designed to withstand the load even when multiple sub-distribution units are installed.

[0065] The busway provides the structural convenience that allows the system to distribute power to multiple electric vehicles.

[0066] Figure 2 shows the relationship between the load power of a public facility and the operation system (100) of charging power for electric vehicles and external devices.

[0067] Referring to FIG. 2, the external device may be any one of the first user terminal (510), the second user terminal (520), and the administrator terminal (600). In addition to those illustrated in FIG. 2, the external device may communicate with the operating system (100) to provide information.

[0068] Although not shown in the drawing, the first user terminal (510) may include a control unit, a communication unit, a storage unit, a display unit, and an input unit.

[0069] The first user terminal (510) can transmit and receive information with the operating system (100) through the communication unit, and can store and execute an application that can be installed on the first user terminal (510) through the storage unit.

[0070] A first user who owns and uses a first user terminal (510) may be someone who uses the load power of a common facility. For example, a resident of an apartment complex may own and use a first user terminal (510) to use the load power of a refrigerator, lights, washing machine, etc.

[0071] The input unit may be configured as an input interface for controlling the first user terminal (510) and may be a keyboard or a touch screen.

[0072] The first user terminal (510) configured in this manner may be, for example, any one of a smartphone, a tablet PC, and a notebook, and even if it is not one of these, it is not limited to the above embodiment as long as it can perform the above functions.

[0073] The description of the second user terminal (520) is the same as that of the first user terminal (510), so it will not be repeated and will be replaced with the description described above.

[0074] However, the second user who owns and uses the second user terminal (520) may be the owner or operator of a vehicle that uses the electric vehicle charging system (400).

[0075] The first user and the second user may be the same person, and thus the first user terminal (510) and the second user terminal (520) may be the same object.

[0076] Although not shown in the drawing, the administrator terminal (600) may include a control unit, a communication unit, a storage unit, a display unit, and an input unit.

[0077] The administrator terminal (600) can transmit and receive information with the operating system (100) through the communication unit, and can store and execute applications that can be installed on the administrator terminal (600) through the storage unit.

[0078] A user who owns and uses an administrator terminal (600) may be an administrator or assistant administrator of the operating system (100). The assistant administrator may share and manage a portion of the operating system (100).

[0079] The input unit may be configured as an input interface for controlling the administrator terminal (600) and may be a keyboard or a touch screen.

[0080] The administrator terminal (600) configured in this manner may be, for example, any one of a smartphone, a tablet PC, and a notebook. Even if it is not one of these, it is not limited to the above embodiment as long as it can perform the above functions.

[0081]

[0082] Figure 3 shows the power transaction relationship between the load power of public facilities and the charging power for electric vehicles.

[0083] Referring to Figure 3, the electric vehicle depicted in the upper right may require 30 kW of power for charging. In this case, the 30 kW of power used by load #3 can be turned off, and the same amount of power can be provided for charging the electric vehicle. In this case, the electric vehicle user may pay an additional fee or receive a deduction of points for charging, while the user of load #3 may receive a discount on their electricity bill or receive an additional point.

[0084] Conversely, load #8 may require 10 kW of power for its usage. In this case, the electric vehicle depicted in the lower right corner can allocate 10 kW of its charging power to load #8 for use. In this case, the user of load #8 can pay an additional fee or receive a deduction of points, while the user of the electric vehicle can receive a discount on the charging fee or receive additional points.

[0085] The above example illustrates the basic transaction concept between load power and charging power in a public facility. However, as illustrated, power need not necessarily be traded on a 1:1 basis or simultaneously. In power transactions, the collection of power-related information and power distribution can be integrated and managed by the operating system (100).

[0086]

[0087] Hereinafter, the operating method of the load power of the public facility and the charging power for electric vehicles will be described, focusing on the operating system (100). Unless otherwise specified, the operating method of the load power of the public facility and the charging power for electric vehicles can be understood as being performed by the operating system (100).

[0088] Figure 4 schematically illustrates the operation method of the load power of a public facility and the charging power for electric vehicles.

[0089] Referring to FIG. 4, in step S100, the operating system (100) sets power transaction conditions.

[0090] The setting information for the power transaction conditions can be set by the first user or the second user, and can be received from the first user terminal (510) or the second user terminal (520).

[0091] At step S200, the operating system (100) predicts the power demand of the loads.

[0092] The power demand of each load can be predicted based on hourly power consumption recorded from power meters (330) installed in each load group or load monitoring devices (350) installed at each load. In the short term, the forecast can be based on yesterday's usage. In the longer term, the forecast can be based on the average usage over the past week. In the longer term, the forecast can be based on usage on the same date last year.

[0093] For prediction, the first user's usage pattern can be analyzed by artificial intelligence machine learning.

[0094] At step S300, the operating system (100) predicts the charging demand of the electric vehicle.

[0095] Predicting the charging demand of electric vehicles can be done more accurately than predicting the demand for load power.

[0096] The charging demand of an electric vehicle can be predicted by receiving reservation information or charging request information in advance from a second user terminal (520) regarding electric vehicle charging.

[0097] The reservation information may include information about the charging time, charging amount, and charging type (which may mean rapid or slow) of the electric vehicle input by the second user through the second user terminal (520) before charging.

[0098] The charging request information may include information about the charging time, charging amount, and charging type (which may mean rapid or slow) of the electric vehicle input by the second user through the second user terminal (520) or the electric vehicle charging system (400) when connecting to the charging terminal.

[0099] If you connect to the charging terminal without entering reservation information or charging request information, the charging schedule may be determined by default.

[0100] If the charging demand forecast for electric vehicles cannot be made using the above-described method, the S200 method can be applied as an auxiliary method.

[0101] At step S400, the operating system (100) operates the distribution of power.

[0102] Power distribution operation can be understood as a concept that includes the distribution of power for each load of a public facility, the distribution of power for each electric vehicle to be charged, and the adjustment and readjustment of the distributed power, such as cutting off or reducing one power and providing it to another.

[0103] At step S500, the operating system (100) operates power distribution.

[0104] Distributed power operation is an activity to stabilize the power grid by distributing power demand in advance by capacity and time zone when the demand for power is expected to be higher than the standard during a specific time zone.

[0105] At step S600, the operating system (100) manages points.

[0106] Point management can be defined as a concept that includes the generation, granting, deduction, use, and settlement of points.

[0107]

[0108] Figure 5 illustrates in detail the power transaction condition setting step (S100).

[0109] The step of setting the power transaction conditions can be divided into steps related to the first user (S110 to S130) and steps related to the second user (S140 to S150).

[0110] In step S110, the operating system (100) sets essential loads and non-essential loads.

[0111] The configuration information for essential and non-essential loads can be set by the first user and received from the first user terminal (510). The first user terminal (510) can be provided with a user interface related to the configuration.

[0112] Critical loads can be defined as loads that must be supplied with power at all times. Examples of critical loads include medical equipment, washing machines, refrigerators, internet routers, and computers.

[0113] Non-essential loads can be defined as loads that can tolerate unannounced power interruptions. Examples of non-essential loads include lighting, air conditioning, and heating appliances.

[0114] Essential and non-essential loads can be defined differently depending on the time of day. For example, lights may be selected as a non-essential load during the day, while lights may be selected as an essential load at night.

[0115] In step S120, the operating system (100) sets priorities among non-essential loads.

[0116] Non-essential load priority information can be set by the first user and received from the first user terminal (510). The first user terminal (510) can be provided with a user interface related to the setting.

[0117] The priority among non-essential loads is about which load among non-essential loads will be blocked with the highest priority and which load will be blocked with the lowest priority.

[0118] In step S130, the operating system (100) sets the trading conditions of load power.

[0119] The transaction condition information for the load power can be set by the first user and received from the first user terminal (510). A user interface related to the setting can be provided to the first user terminal (510).

[0120] The terms of the load power transaction may be an expression of willingness to conditionally comply with the load power when it becomes necessary to cut off the load power.

[0121] The trading conditions for load power can be set in various forms, for example, unconditionally for non-essential loads, depending on the time for essential loads, depending on the time for non-essential loads, or depending on the relationship with other loads.

[0122] For example, essential equipment such as an internet router may not be used during sleep hours, so you can set it to be available for trading during those hours.

[0123] For example, if a first light group and a second light group are installed in a space divided into the same room, the second light group can be set to be transacted when the first light group is turned on.

[0124] In step S140, the operating system (100) receives charging request information.

[0125] Charging request information may be set by a second user and received from a second user terminal (520). A user interface related to the setting may be provided to the second user terminal (520).

[0126] The charging request information may include at least one of charging amount, charging time, and charging type.

[0127] In step S150, the operating system (100) sets charging power transaction conditions.

[0128] The charging power transaction condition information can be entered by a second user and received from a second user terminal (520). A user interface related to settings can be provided to the second user terminal (520).

[0129] The terms of the charging power transaction may be an expression of willingness to conditionally comply with the requirement to use all or part of the charging power for a certain load.

[0130] The charging power transaction conditions can be either conditions regarding charging amount or conditions regarding charging time.

[0131] Conditions regarding the charge amount can be conditions regarding the target charge amount, such as a charge of 80% or more. Conditions regarding the charge amount can be conditions within a preset range, such as a charge of 25% or more and 75% or less.

[0132] Conditions regarding charging time can be set to 2 hours or more, 6 hours or more, etc. Conditions regarding charging time can be selected along with the charging type.

[0133] If the set conditions are met, at least some of the allocated charging power can be traded.

[0134]

[0135] Figure 6 illustrates in detail the power distribution operation step (S400).

[0136] The power distribution operation can be broadly divided into a step for supplementing load power (S410 to S415) and a step for supplementing charging power (S420 to S424).

[0137] In step S410, the operating system (100) determines whether the predicted or current load power demand exceeds the target power. If the target power is exceeded, the process proceeds to step S411, and if not, the process proceeds to step S430.

[0138] The target power may be the amount of power that the users or managers of the public facility have decided in advance to use at a certain level.

[0139] For example, setting the target power can prevent excessive charging of electricity rates by lowering the maximum demand power (peak power).

[0140] In step S411, the operating system (100) checks the state of charge (Soc) of the energy storage device (200).

[0141] Checking the charge status can mean determining the current charge level.

[0142] In step S412, the operating system (100) selects an additional supply source for load power according to the charging state of the energy storage device (200).

[0143] The additional supply source may be at least one of the energy storage device (200) and the charging power distributed to the electric vehicle.

[0144] First, when the charging status of the energy storage device (200) is below a set value, the charging power distributed to the electric vehicle can be selected as an additional supply source.

[0145] Second, if the charge status of the energy storage device (200) is higher than the set value and the required power amount is lower than the charge amount of the energy storage device (200), the energy storage device (200) can be selected as an additional power supply source.

[0146] Thirdly, when the charge status of the energy storage device (200) is higher than the set value and the required power amount exceeds the charge amount, both the energy storage device (200) and the charging power distributed to the electric vehicle can be selected as an additional supply source.

[0147] Here, the set value may be the minimum charge amount that the energy storage device (200) must maintain.

[0148] Here, the demanded power may be the excess power when the power demand exceeds the target power.

[0149] In step S413, the operating system (100) supplies power to the power source selected in step S412 according to preset transaction conditions.

[0150] Here, power supply may be provided by limiting the power provided for charging when the selected source is charging power distributed to electric vehicles, and then providing the power requested by the public facility. This explanation is based on the concept of power trading. In practice, power restriction and provision do not necessarily need to occur simultaneously, and power for public facility loads can be provided as requested. However, for transaction management, the secondary user associated with the restricted power and the primary user associated with the provision must be recorded. If it is difficult to identify the primary user, transaction-related information, such as points, can be distributed and applied to all primary users or multiple primary users.

[0151] The preset transaction conditions are as described above. For example, if the second user requests 80% charging capacity, 30 kW is allocated for charging, the target charging capacity is set to 50%, and 60% charging has occurred, and the requested power is 10 kW, 10 kW of the allocated 30 kW can be reduced and charging can be performed at 20 kW. For example, if the requested power is 40 kW, charging can be stopped, 30 kW can be diverted to the public facility, and the remaining 10 kW can be supplied by the energy storage device (200).

[0152] If the transaction conditions of multiple second users are met, criteria for priority in selecting a supplier can be set in advance.

[0153] For example, among vehicles that have been charged above the target amount, priority can be determined based on the highest amount charged.

[0154] For example, priority may be given to second-tier users with lower past transaction volume.

[0155] For example, priority may be given to a second user who has a long charging time or a slow charging type.

[0156] In step S414, the operating system (100) compensates for the charging power.

[0157] Compensation for charging power can be defined as the concept of returning the charging power equivalent to the amount used. This compensation can be implemented during times when the load's power demand is relatively low.

[0158] For example, if all of the charging power of a vehicle that was allocated 10 kW of charging power for 8 hours is traded for 2 hours and used as load power, 20 kW of charging power can be allocated for 2 hours out of the remaining 6 hours to meet the charging amount requested by the second user.

[0159] In step S415, the operating system (100) generates first related point information.

[0160] The first related point information may be the point addition and deduction between the first and second users involved in the transaction when the load power is supplemented with charging power. If the load power is supplemented solely by the energy storage device (200), the points may not change.

[0161] For example, points may be added to a second user associated with a vehicle that provided charging power, and points may be deducted from a first user that received supplemental load power.

[0162] The above example illustrates the distribution of allocated charging power, but it's also possible to use electricity already charged in an electric vehicle, i.e., to discharge the electric vehicle's battery. Of course, in this case, obtaining the consent and condition setting information from the second user in advance is necessary. The method for trading power stored in the battery can be implemented using steps S411 to S415. In this case, the charging power may be power stored in the battery.

[0163]

[0164] At step S420, the operating system (100) determines whether the predicted or current charging power demand exceeds the allowable power. If the allowable power is exceeded, the process proceeds to step S421. If the allowable power is not exceeded, the process proceeds to step S430.

[0165] The allowable power may be the maximum power distributed to the charging system. However, this does not necessarily have to be limited to this, and the concept of target power described above may also be applied.

[0166] In step S421, the operating system (100) checks the state of charge (Soc) of the energy storage device (200).

[0167] In step S422, the operating system (100) selects an additional supply source for charging power according to the charging state of the energy storage device (200).

[0168] The additional supply source may be at least one of an energy storage device (200) and a load power source.

[0169] First, when the charge status of the energy storage device (200) is below the set value, the load power can be selected as an additional supply source.

[0170] Second, if the charge status of the energy storage device (200) is higher than the set value and the required power amount is lower than the charge amount of the energy storage device (200), the energy storage device (200) can be selected as an additional power supply source.

[0171] Thirdly, when the charge status of the energy storage device (200) is higher than the set value and the required power amount exceeds the charge amount, both the energy storage device (200) and the load power can be selected as additional supply sources.

[0172] Here, the set value may be the minimum charge amount that the energy storage device (200) must maintain.

[0173] Here, the demanded power may be the excess power when the charging power demand exceeds the allowable power.

[0174] In step S423, the operating system (100) supplies power to the power source selected in step S422 according to preset transaction conditions.

[0175] Here, power supply may involve interrupting the load power, if the selected power source is load power, and then providing the power requested by the charging system. This explanation is based on the concept of power trading. In practice, power interruption and provision do not necessarily need to occur simultaneously; power from the charging system can be provided as requested. However, for transaction management, the primary user associated with the interrupted power and the secondary user associated with the provision must be recorded. If it is difficult to identify the secondary user, transaction-related information, such as points, can be distributed and applied to all secondary users or multiple secondary users.

[0176] The preset transaction conditions are as described above. For example, if a second user requests a charging power of 30 kW and this needs to be partially covered by the load power, the power supplied to the first user's air conditioner can be cut off.

[0177] If the transaction conditions of multiple primary users are met, criteria for priority in selecting a supplier can be set in advance.

[0178] For example, priority may be determined in the order of first users with high non-essential load.

[0179] For example, priority may be determined by the first user with the lowest past transaction volume.

[0180] For example, essential loads may be prioritized to be traded after all non-essential loads have been traded.

[0181] In step S424, the operating system (100) generates second related point information.

[0182] The second related point information may be the point addition and deduction between the first and second users involved in the transaction when charging power is supplemented with load power. If the charging power is supplemented solely by the energy storage device (200), the points may not change.

[0183] For example, points may be added to the first user who provides the load power, and points may be deducted to the second user who receives the charging power.

[0184] At step S430, the operating system (100) operates power in a conventional manner.

[0185] Here, the conventional method may mean a general power supply method that operates without power trading.

[0186]

[0187] Figure 7 illustrates in detail the distributed power operation step (S500).

[0188] Referring to FIG. 7, the operating system (100) determines the necessity of distribution. If distribution is necessary, the process proceeds to step S520, and if not necessary, the process returns to step S400.

[0189] Here, power distribution can mean widely distributing the power distributed to each load and charging vehicle over time. In other words, it reduces the standard deviation of the total power consumption.

[0190] Power distribution may be necessary when the load power demand and charging power demand are concentrated at a specific time period, making it difficult to resolve even with the S400 method.

[0191] In step S520, the operating system (100) transmits power distribution request information to at least one of the first user terminal (510) and the second user terminal (520).

[0192] The first user can verify the distributed request information and, in response, power off one or more of the loads.

[0193] The second user can check the distributed request information and change the charging request information.

[0194] In step S530, the operating system (100) determines whether to respond to the power distribution request.

[0195] For example, if there is a need to distribute power from 6:00 PM to 7:00 PM, and a second user changes the charging time from 6:00 PM to 10:00 PM to 7:00 PM to 11:00 PM, the user can be judged to have cooperated with the power distribution request.

[0196] For example, if there is a need to distribute power from 1:00 PM to 4:00 PM, and the first user turns off the air conditioner from 1:00 PM to 4:00 PM, the user can be judged to have cooperated with the power distribution request.

[0197] However, because the loads and usage patterns of primary users can vary, it can be difficult to identify the primary user who cooperated with the power sharing request. One method for identifying the primary user is to identify a user who powers off the load within a preset time after sending the power sharing request as the primary user who cooperated with the power sharing request.

[0198] Another method is to identify the first user who cooperated with the power sharing request by averaging the usage for a certain period of time, such as weekly, monthly, or yearly, and comparing it with the past usage of the same user at the same time before the power sharing request, the current usage of another user, or the past usage of another user at the same time before the power sharing request. For example, if a power sharing request is sent from 1:00 PM to 4:00 PM on the first weekend of August, if the first user's power usage from 1:00 PM to 4:00 PM on the second week of August has decreased by a preset threshold value compared to the first week of August, that first user can be identified as the first user who cooperated with the power sharing request. The power usage can also be compared with the power usage on the same day last year.

[0199] In step S540, the operating system (100) generates third related point information.

[0200] The third related point information may be information regarding the addition of points to the first and second users who cooperated with the power distribution request, when it is determined that they cooperated. Conversely, the operating system (100) may deduct points from users who actually increased their power usage when a power distribution request is made.

[0201]

[0202] Figure 8 illustrates the point management step (S600) in detail.

[0203] In step S610, the operating system (100) determines where points will be used. Information regarding the determination of where points will be used may be selected and received from the first user terminal (510) or the second user terminal (520).

[0204] Points can be used for any of the following purposes: using the points themselves, converting them to actual money, or reflecting them in management fees.

[0205] At step S620, the operating system (100) converts points into money and deposits them to the user or reflects them in the management fee.

[0206] At step S630, the operating system (100) uses points according to the user's request.

[0207] Points can be used in a variety of ways. For example, they can be used to purchase necessary items related to electric vehicle maintenance or household needs. For example, points can be used to obtain priority access to electric vehicle charging stations.
