[0023] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the drawings of the specification. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should be within the scope of protection of the present application.
[0024] Embodiment 1, refer to Figure 1 For an embodiment of the present application, an electric vehicle ordered charging strategy optimization method is provided, which comprises: S1: based on the cooperative analysis of electric vehicle user charging behavior data and charging pile dynamic operation parameters, a dynamic cost optimization model under the multi-time period electricity price response mechanism is constructed.
[0025] It should be noted that the implementation purpose is to construct the charging strategy objective function with the lowest electricity purchase cost as the target, which is an important factor of the charging optimization strategy, and realizes the overall electricity purchase cost reduction.
[0026] The optimization objective function is to minimize the electricity purchase cost, and the electricity purchase cost optimization objective function is represented as: , wherein, represents the electricity purchase cost of the vth electric vehicle, represents the number of charging periods, represents the duration of the charging period; represents the time-of-use electricity price of the tth charging period power spot market, published by the market trading platform, represents the charging power in the tth charging period.
[0027] The electricity purchase strategy optimization constraints include charging power constraints and charging time constraints.
[0028] It should be noted that the implementation aims to build electricity purchase strategy optimization constraints as constraint items of the charging optimization strategy to meet the operation requirements.
[0029] The charging power constraints include that the charging power cannot exceed the charging pile and the electric vehicle charging power limit range, and the charging power corresponding to the charging capacity should meet the customer's expected charging capacity requirements, represented as: , , wherein, represents the charging power limit determined by the electric vehicle itself, represents the charging power limit determined by the charging pile device itself, represents the expected charging capacity of the vth electric vehicle customer, represents the number of charging periods.
[0030] The charging time constraints include that the charging time cannot exceed the customer's expected charging time limit, i.e., the optimization of charging power cannot result in excessively long charging time, which in turn affects the normal use of customers. Also, the charging time cannot exceed the expected loss of charging pile operator resource occupation, represented as: , , wherein, represents the customer's expected charging time limit, set by the electric vehicle charging user, represents the number of charging periods, represents the expected loss of charging pile operator resource occupation time limit, represents the duration of the charging period.
[0031] In summary, by double power constraint (user equipment end + charging pile end) to avoid overload risk, while ensuring user charging capacity demand rigid satisfaction; Introducing the expected loss of resource occupation time limit, while reducing the cost of electricity purchase, prevent excessive extension of charging time leading to user loss or operator revenue loss; Time-of-use pricing mechanism design makes the model dynamic response to power market fluctuations, laying the foundation for subsequent real-time optimization.
[0032] S2: Adopting dynamic programming algorithm and charging resource occupation risk prediction closed-loop feedback mechanism, through the interaction iteration of real-time electricity price signal and charging pile state monitoring data, solving the asymmetric charging power allocation scheme that meets the spatial and temporal distribution characteristics of charging demand.
[0033] The charging strategy optimization model takes the lowest electricity purchase cost as the optimization objective, and considers the charging power and charging time constraints, which is represented as: , Among them, The electricity purchase cost of the vth electric vehicle is represented as v, and the Cplex solver is used to solve the charging strategy with the lowest electricity purchase cost as the optimization objective.
[0034] In summary, by dynamic programming algorithm to deal with the space-time imbalance of charging demand, generate "asymmetric allocation scheme" (such as concentrated charging in low valley period and reduced power in peak period), which significantly improves the grid load rate; Charging resource occupation risk prediction module real-time evaluation pile group state (such as congestion probability), avoid local resource overload leading to optimization failure; Using Cplex solver to process high-dimensional nonlinear constraints, while ensuring global optimal solution, meet the real-time calculation demand (second-level response) of large-scale electric vehicle group control.
[0035] S3: Establish a double-layer convergence criterion based on charging load transfer elasticity evaluation, by quantifying the dynamic game relationship between user economic benefits generated by charging strategy optimization and opportunity cost of charging facility resource occupation, implement the economic-resource utilization Pareto optimal boundary judgment of charging strategy, when the user cost reduction brought by strategy optimization exceeds the service capacity damage threshold of charging pile, output the optimal orderly charging strategy that meets the dynamic balance of the system.
[0036] It should be noted that the purpose of implementation is to evaluate the economic loss that may be caused by the optimization strategy according to the charging time of electric vehicles. The evaluation idea is to measure the expected economic loss caused by the time extension caused by the optimization of charging strategy according to the number of electric vehicles charging at the same period in history.
[0037] The delay of optimization strategy is the difference between the charging time after adopting the charging strategy optimization method and the traditional constant power charging time with maximum charging power, which is represented as: , wherein, denotes the optimization strategy delay, denotes the number of charging periods, denotes the duration of the charging period, denotes the expected charging amount of the vth electric vehicle customer, denotes the charging power limit determined by the electric vehicle itself setting, is the ratio of the customer's expected charging amount to the maximum charging power.
[0038] The statistical contemporaneous charging frequency is represented as: , wherein, denotes the contemporaneous charging frequency, denotes the number of electric vehicles charged by the historical contemporaneous charging pile within the charging time corresponding to the optimization charging strategy, if the evaluation object is a charging station, it is the average number of electric vehicles charged corresponding to each charging pile.
[0039] The expected loss of charging resource occupation is calculated and represented as: , wherein, denotes the expected loss of charging resource occupation, denotes the contemporaneous charging frequency, denotes the average charging service fee income of the charging pile operator during the charging of the electric vehicle, is the optimization strategy delay.
[0040] It should be noted that the purpose of judging the convergence condition is to compare the change in electricity purchase cost generated by the optimization strategy with the expected loss of charging resource occupation, and to adjust the charging pile operator's resource occupation expected loss time limit for scenarios that do not meet the convergence condition.
[0041] The convergence condition is that the decrease in electricity purchase cost generated by the optimization strategy is greater than the charging pile service capacity loss threshold, i.e., the expected loss of charging resource occupation, which can be represented as: , wherein, denotes the expected loss of charging resource occupation, denotes the electricity purchase cost of the vth electric vehicle, is the electricity purchase cost under the traditional maximum charging power constant power mode, which can be represented as: , wherein, denotes the time-of-use electricity price of the power spot market in the charging period t, denotes the number of charging times under the traditional maximum charging power constant power mode, denotes the duration of the charging period, represents a charging power limit determined by the electric vehicle itself setting.
[0042] If the convergence condition is met, the convergence requirement is met, indicating that the optimized charging strategy meets the convergence condition, and the charging strategy is output.
[0043] If the convergence condition is not met, the charging pile operator resource occupation expected loss time limit is reduced.
[0044] In summary, through the economic-resource utilization Pareto boundary determination, the single pursuit of reducing electricity purchase is avoided, and the operator's interests are sacrificed (such as excessive time extension leading to a decrease in charging pile turnover rate); the charging load transfer elasticity concept (user tolerance to charging time extension and sensitivity to economic benefits) is introduced, making the strategy more in line with real user behavior; when the user cost reduction does not exceed the service capacity loss threshold, the resource occupation time limit is automatically reduced and re-optimized, ensuring that the strategy always converges within the system's bearable boundary.
[0045] Embodiment 2, refer to Figure 3 As an embodiment of the present application, the embodiment provides an electric vehicle orderly charging strategy optimization system, comprising a model construction module, a solving module and a convergence module.
[0046] The model construction module constructs a charging strategy objective function with the lowest electricity purchase as the target based on the charging demand of electric vehicle customers and the operating state of charging piles, and constructs the electricity purchase strategy optimization constraint condition.
[0047] The solving module constructs a charging strategy optimization model and solves it according to the target function and constraint condition.
[0048] The convergence module establishes a double-layer convergence criterion based on charging load transfer elasticity evaluation, implements economic-resource utilization Pareto optimal boundary determination of charging strategy, and outputs the optimal orderly charging strategy that meets the system dynamic balance.
[0049] The embodiment also provides an electronic device suitable for the case of an electric vehicle orderly charging strategy optimization method, comprising a memory and a processor; the memory is used to store computer executable instructions, and the processor is used to execute the computer executable instructions to realize an electric vehicle orderly charging strategy optimization method as proposed in the above embodiment.
[0050] The embodiment also provides a storage medium having a computer program stored thereon, which is executed by a processor to realize an electric vehicle orderly charging strategy optimization method as proposed in the above embodiment.
[0051] The storage medium provided in the embodiment belongs to the same inventive concept as the method for optimizing an orderly charging strategy of an electric vehicle provided in the above embodiment, and the technical details not described in detail in the embodiment can be seen from the above embodiment, and the embodiment has the same beneficial effects as the above embodiment.
[0052] Through the above description of the embodiments, those skilled in the art can clearly understand that the present application can be realized by means of software and necessary general hardware, and of course can also be realized by hardware, but in many cases the former is a better embodiment. Based on such understanding, the technical solutions of the present application can be embodied in the form of a software product, which can be stored in a computer readable storage medium, such as a floppy disk, a read-only memory (ROM), a random access memory (RAM), a FLASH, a hard disk or an optical disk, etc., including a number of instructions to make a computer device (which can be a personal computer, a server, or a network device, etc.) execute the methods of various embodiments of the present application.
[0053] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting, and although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced by equivalents without departing from the spirit and scope of the present application, and all should be covered in the scope of the claims of the present application Embodiment 3, refer to Figure 2 For an embodiment of the present application, a method, system, device and medium for optimizing an orderly charging strategy of an electric vehicle are provided, and in order to verify the beneficial effects of the present application, scientific demonstration is carried out through simulation experiments.
[0054] As Figure 2 shown, it is the time-of-use price of a certain charging station power spot market. Taking an electric vehicle charging before 08:00 as an example, the maximum charging power of the charging station is 10 kW, and the electric vehicle charging demand is 30 kWh.
[0055] According to the constant power charging strategy based on the maximum charging power, the charging station will charge the electric vehicle at a power of 10 kW, and it is expected to be fully charged at 11:00, and the charging cost is 9.63 yuan.
[0056] With the method, the optimal charging time period is 10:00-13:00, and the corresponding charging cost is 6.80 yuan. However, if only the minimum charging cost is considered, the electric vehicle may occupy the charging station parking space for a long time, affecting the charging of other electric vehicles. Therefore, the expected loss of charging resource occupation is evaluated by the method of step four. After evaluation, the convergence requirement is met by considering the expected loss of occupation.
[0057] Table 1 compares the constant power charging strategy based on the maximum charging power and the charging strategy of the method. It can be seen that the method proposed in the application will reduce the charging cost by 29.40% for the case.

Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced by equivalents without departing from the spirit and scope of the present application, which should be covered by the scope of the claims of the present application.
