[0028] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0029] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in a sequence other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0030] According to an embodiment of the present application, a method embodiment of a method for determining the dispatchable capacity of a charging resource is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0031] Figure 1 is a flow chart of a method for determining the dispatchable capacity of charging resources according to an embodiment of the present application, such as Figure 1 As shown, the method includes the following steps:

[0032] Step S102, determining a first function and a second function corresponding to the charging time of the first electric vehicle, wherein the first function is used to characterize the relationship between time and a lower limit of a first power consumption, and the second function is used to characterize the relationship between time and an upper limit of the first power consumption, and the first electric vehicle is an electric vehicle that does not support discharge.

[0033] Electric vehicles that do not support discharge are those that do not store and release energy through the vehicle itself. These vehicles charge their batteries with electricity from an external power source, which then converts the stored energy into mechanical energy to propel the vehicle. These electric vehicles do not support discharge, meaning they cannot release the energy from their batteries or convert the vehicle's kinetic energy into electrical energy for storage.

[0034] Step S104, determining a third function and a fourth function corresponding to the charging and discharging time of the second electric vehicle, wherein the third function is used to characterize the relationship between time and the lower limit of the second power consumption, and the fourth function is used to characterize the relationship between time and the upper limit of the second power consumption, and the second electric vehicle is an electric vehicle that supports discharge.

[0035] Electric vehicles that support discharge, such as those supporting V2G (Vehicle-to-Grid), refer to the use of electric vehicle battery energy for grid services. V2G technology allows for a two-way energy exchange between electric vehicles and the grid. When needed, electric vehicles can release energy stored in their batteries to the grid, providing power to the grid. When the electric vehicle does not need energy, the grid can charge the electric vehicle's batteries to store energy. Through V2G technology, electric vehicles can become part of the grid, participating in power dispatch and energy balancing, improving grid stability and reliability. V2G technology can also provide additional economic benefits for electric vehicle owners. By participating in grid dispatch and energy markets, owners can sell excess electricity to the grid or participate in electricity market transactions.

[0036] Step S106 : determining the dispatchable amount of power of the first electric vehicle at a first target time according to the first function and the second function, wherein the first target time is any time within the charging time.

[0037] Step S108: determining the dispatchable amount of power of the second electric vehicle at a second target time according to the third function and the fourth function, wherein the second target time is any time within the charge and discharge time.

[0038] According to the above steps, the dispatchable power of the electric vehicle at the target time is determined based on the function corresponding to time and power consumption, thereby achieving the purpose of evaluating the power consumption during the charging and discharging process of the electric vehicle, thereby realizing the technical effect of efficiently dispatching the charging resources during the charging and discharging process of the electric vehicle.

[0039] According to some optional embodiments of the present application, determining a first function and a second function corresponding to a first electric vehicle within a charging time includes the following steps: determining the first function based on a first electric power, a second electric power, a first preset minimum charging power, a first rated charging power, a first charging efficiency, a charging start time, and a charging end time of the first electric vehicle, wherein the first electric power is the electric power of the first electric vehicle at the charging start time, and the second electric power is the electric power of the first electric vehicle at the charging end time; determining the second function based on the first rated charging power, the first charging efficiency, the first preset maximum charging power, and the first electric power of the first electric vehicle.

[0040] For When the charging start time arrives, For an electric vehicle that leaves at time (charging end time), when the electric vehicle is not allowed to discharge, the upper and lower bounds of the accumulated power consumption of the electric vehicle over time are as follows: Figure 2 As shown. Figure 2 middle, Indicates the size of the electric vehicle battery capacity (the first preset maximum charging capacity), Indicates the amount of electricity the electric vehicle has when it is connected (the first amount of electricity). represents the minimum amount of electricity (second amount of electricity) that the electric vehicle needs to reach when leaving, η j It is the charging efficiency.

[0041] from Figure 2 It can be seen from the figure that, when only the charging situation is considered, the upper bound of the cumulative power consumption of electric vehicles (the first upper bound of power consumption) is This is in contrast to the fastest electricity consumption trajectory (ABC). On this trajectory, electric vehicles Once connected, it will be charged at rated power until the state of charge reaches the maximum The lower limit of the cumulative power consumption (the first lower limit of power consumption) E j (t) corresponds to another extreme case (ADE): the electric vehicle is not charged after being connected, and when it is close to the time of leaving the electric vehicle When the electric vehicle is charged to the minimum value set by the user at the rated power (First preset minimum charging power).

[0042] The above description can be expressed as follows:

[0043]

[0044]

[0045] According to other optional embodiments of the present application, determining the third function and the fourth function corresponding to the second electric vehicle within the charging and discharging time can be achieved by the following method: determining the third function according to the third power, the fourth power, the second preset minimum charging power, the rated discharge power, the second rated charging power, the second charging efficiency, the start time of charging and discharging, and the end time of charging and discharging of the second electric vehicle, wherein the third power is the power of the second electric vehicle at the start time of charging and discharging, and the fourth power is the power of the second electric vehicle at the end time of charging and discharging; determining the fourth function according to the second rated charging power, the second charging efficiency, the second preset maximum charging power and the third power of the second electric vehicle.

[0046] For When the time (charge and discharge start time) arrives, For an electric vehicle that leaves at time (the end of charging and discharging), when the electric vehicle has V2G capability, the upper and lower bounds of the cumulative power consumption of the electric vehicle over time are as follows: Figure 3 As shown by Figure 3 It can be seen that the upper bound of the cumulative power consumption of electric vehicles with V2G capabilities is the same as that of the electric vehicles only considering charging, and the corresponding trajectory is (ABC). However, the lower bound of the cumulative power consumption is different from that of the case of only considering charging, and its corresponding trajectory is (ADEF). On this trajectory, the electric vehicle After the charging and discharging start time is connected, the rated discharge power Discharge until the initial charge (Third power) until it is empty, when it is close to the time to leave At the end of charging and discharging, the electric vehicle is charged at the rated power. (Second rated charging power) Charge the battery to the minimum value set by the user (Second preset minimum charging power). Therefore, the upper and lower bounds of the power and cumulative power consumption obtained above describe the feasible range of the charging and discharging power of electric vehicles with V2G capabilities over time. The above description can be expressed by the following function:

[0047]

[0048]

[0050] As some optional embodiments of the present application, determining a first power boundary of a first electric vehicle within a charging time is achieved by the following method: determining a first power lower boundary as 0; determining a first power upper boundary based on a first rated charging power; determining a second power boundary of a second electric vehicle within a charging and discharging time is achieved by the following method: determining a second power lower boundary as 0; determining a second power upper boundary based on a rated discharge power.

[0051] For Arrival at the time For electric vehicles that leave at any time, if the electric vehicle does not support discharge, the charging power during the docking time can be continuously adjusted from 0 to the rated power. During the non-docking time, the charging power must be strictly 0, so the power boundary Pj (t) and They are:

[0052]

[0053]

[0054] in, is the rated charging power of electric vehicle j.

[0055] For Arrival at the time For an electric vehicle that leaves at any moment, under the condition that the electric vehicle supports discharge, the upper and lower bounds of its power consumption over time can be expressed as:

[0056]

[0057]

[0059] In some optional embodiments of the present application, the charging time of the first electric vehicle is divided into x first preset time periods, and a first function of time and a lower bound of first power consumption and a second function of time and an upper bound of first power consumption are determined for each first preset time period of the x first preset time periods, respectively, where x is a positive integer determined according to a charging resource scheduling system to be connected to the first electric vehicle; the charging and discharging time of the second electric vehicle is divided into y second preset time periods, and a third function of time and a lower bound of second power consumption and a fourth function of time and an upper bound of second power consumption are determined for each second preset time period of the y second preset time periods, respectively, where y is a positive integer determined according to a charging resource scheduling system to be connected to the second electric vehicle; based on the first function and the second function, the dispatchable power of the first electric vehicle at a third target time is determined, respectively, where the third target time is any time within each first preset time period; based on the third function and the fourth function, the dispatchable power of the second electric vehicle at a fourth target time is determined, respectively, where the fourth target time is any time within each second preset time period.

[0060] Optionally, the entire scheduling time window is divided into n1 time periods (x first preset time periods) at a time interval ΔT1, and the charge and discharge adjustable range of an electric vehicle j can be expressed by the power-energy boundary quadruple To express.

[0061] For When the charging start time arrives, For an electric vehicle that leaves at the end of charging, if it does not support discharge, its charging power can be continuously adjusted from 0 to the rated power during the docking time, and its charging power must be strictly 0 during the non-docking time. Therefore, the power boundary P j (t) and They are:

[0062]

[0063]

[0064] For When the charging start time arrives, For an electric vehicle that leaves at time (charging end time), when the electric vehicle is not allowed to discharge, the upper and lower bounds of the accumulated power consumption of the electric vehicle over time are as follows: Figure 2 As shown. Figure 2 middle, Indicates the size of the electric vehicle battery capacity (the first preset maximum charging capacity), Indicates the amount of electricity the electric vehicle has when it is connected (the first amount of electricity). represents the minimum amount of electricity (second amount of electricity) that the electric vehicle needs to reach when leaving, η j It is the charging efficiency.

[0065] from Figure 2 It can be seen that the upper bound of the cumulative power consumption of electric vehicles considering only the charging situation (the first upper bound of power consumption) is This is in contrast to the fastest electricity consumption trajectory (ABC). On this trajectory, electric vehicles Once connected, it will be charged at rated power until the state of charge reaches the maximum The lower limit of the cumulative power consumption (the first lower limit of power consumption) E j (t) corresponds to another extreme case (ADE): the electric vehicle is not charged after being connected, and when it is close to the time of leaving the electric vehicle When the electric vehicle is charged to the minimum value set by the user at the rated power

[0066] The above description can be expressed as follows:

[0067]

[0068]

[0069] Optionally, the entire scheduling time window is divided into n2 time periods at a time interval ΔT2 (the charging and discharging time of the second electric vehicle is divided into y second preset time periods). When the time (charge and discharge start time) arrives, For an electric vehicle that leaves at time (the end of charging and discharging), under the condition that the electric vehicle supports discharge, the upper and lower bounds of its power consumption over time can be expressed as:

[0070]

[0071]

[0072] For When the time (charge and discharge start time) arrives, For an electric vehicle that leaves at time (the end of charging and discharging), when the electric vehicle has V2G capability, the upper and lower bounds of the cumulative power consumption of the electric vehicle over time are as follows: Figure 3 As shown, in Figure 3 In the above example, the upper bound of the cumulative power consumption of electric vehicles with V2G capability is the same as that of the electric vehicles only considering charging, and the corresponding trajectory is (ABC). However, the lower bound of the cumulative power consumption is different from that of the case of only considering charging, and its corresponding trajectory is (ADEF). On this trajectory, electric vehicles After the charging and discharging start time is connected, the rated discharge power Discharge until the initial charge (Third power) until it is empty, when it is close to the time to leave At the end of charging and discharging, the electric vehicle is charged at the rated power. (Second rated charging power) Charge the battery to the minimum value set by the user (First preset minimum charging power). Therefore, the upper and lower bounds of the power and cumulative power consumption obtained above describe the feasible range of the charging and discharging power of electric vehicles with V2G capabilities over time. The above description can be expressed by the following function:

[0073]

[0074]

[0075] As other optional embodiments of the present application, when there are multiple electric vehicles, the power lower bound and power upper bound of each electric vehicle in the multiple electric vehicles are determined separately, and the lower bound and upper bound of power consumption of each electric vehicle are determined separately, wherein the electric vehicle is the first electric vehicle or the second electric vehicle; the power lower bound and the power upper bound of each electric vehicle are summed separately to obtain the total power lower bound and the total power upper bound; the power consumption lower bound and the power consumption upper bound of each electric vehicle are summed separately to obtain the total power consumption lower bound and the total power consumption upper bound; it is determined that the total power to be dispatched of the multiple electric vehicles is between the total power lower bound and the total power upper bound; it is determined that the total power to be dispatched of the multiple electric vehicles is between the total power lower bound and the total power upper bound.

[0076] Based on the dispatchability model of a single electric vehicle flexible resource, for the case of aggregating multiple electric vehicles, the upper and lower bounds of the collective average power and the upper and lower bounds of the cumulative power consumption can be used. To describe.

[0077] Specifically, first, the power energy boundary of a single electric vehicle is constructed based on whether the electric vehicle has V2G capability. Then, the upper and lower bounds of the average power and the upper and lower bounds of the cumulative power consumption of all electric vehicles are summed up, namely:

[0078]

[0079]

[0080] Where: A collection of all electric vehicles.

[0081] The total power P(t) of the electric vehicle cluster should satisfy:

[0082]

[0083]

[0084] This application takes into account the relatively random nature of charging behavior of a single electric vehicle and establishes a dispatchable capacity assessment model for electric vehicle charging and discharging based on charging stations. This model obtains the dispatchable capacity boundary at the station level, prepares the constraint conditions for the algorithm model of the subsequent orderly charging scheduling strategy, and achieves a quantitative description of the upper and lower bounds of charging power and energy at the station throughout the day.
