[0030] Embodiment 1:

[0031] As urban mobility undergoes a transformation phase of automation, electrification, and shared mobility integration, the shared autonomous electric vehicle industry has great potential as a pioneer of future smart city transportation systems. The operating process of the autonomous electric shared vehicle system discussed in this application is as follows: Figure 1As shown, it can be seen from the figure that the user sends travel information to the system control center through the mobile application, and the system will allocate a nearby idle autonomous electric shared car to pick up the user. For the sake of convenience of description, hereinafter the autonomous electric shared car will be simply referred to as the vehicle.

[0032] The departure place and destination of User 1 are in different regions. After Vehicle 1 picks up User 1, it first arrives at the starting point of the link connecting the two regions, passes through the link to the end point of the link in the destination region, and finally delivers to the destination. The destination of User 2 is a certain place within the departure region, and Vehicle 2 can directly send the user to the destination without passing through the link. For users whose ride demands have been met, they will exit the autonomous electric shared car system after arriving at the destination, such as Figure 1 User 1 and User 2 in Figure 1 . However, when the user's waiting willingness is exceeded but there is still no matching vehicle, the user will also leave the system, such as

[0033] User 4 in Figure 1 . When the vehicle sends the user to the destination, it will automatically judge the charging situation. If the battery power does not meet the charging lower limit of the current region, it needs to go to the charging station in the current region for charging, such as Figure 1 Car 2 in

[0034] . If the vehicle's battery is fully charged, it will enter the waiting matching sequence, such as Figure 1 Car 3 in

[0034] After the car in the waiting sequence receives a new order, it will pick up the user according to the address on the order. For example, after Car 1 in the figure sends User 1 to the destination and receives the order of User 3, it will go to the departure place of User 3. If the car in the waiting sequence does not receive any order, it needs to wait in place all the time.

[0035] This embodiment provides an optimization method for the charging strategy of the charging station and the trip pricing strategy.

[0036] Referring to Figure 2 , the figure shows that this method includes Step S10, Step S20, Step S30 and Step S40.

[0037] Step S10. Obtain the charging strategy of the station and the pricing strategy of the region, and determine a plurality of basic parameters. The charging strategy of the station is used to characterize the charging upper and lower limits of the vehicle at different charging stations, and the pricing strategy of the region is used to characterize the operating price setting of the vehicle in different operating regions;

[0038] Specifically, the charging strategy for stations dynamically adjusts the charging upper and lower limits for different regions at different time periods. After each vehicle completes an order-taking task, it needs to conduct a charging assessment, that is, compare the relationship between the current battery level and the currently set charging lower limit in the region where it is located. Only vehicles with a battery level exceeding this lower limit can enter the order waiting queue. If the battery level is lower than this lower limit, the vehicle will be guided to a charging station for charging.

[0039] The regional pricing strategy dynamically adjusts the operating unit price for different regions at different time periods. During certain time periods, the supply and demand of vehicles are unbalanced, which will seriously affect the operating stability of the autonomous electric shared vehicle system. Therefore, by increasing or decreasing the operating profit and the number of vehicles in the fleet, the problem of supply and demand imbalance can be properly addressed to ensure the efficient travel of users.

[0040] Step S20. Construct an optimization model based on multiple basic parameters to obtain a target programming model;

[0041] Specifically, the target programming model aims to maximize the net profit during the operating cycle under the dynamic pricing and charging threshold strategies.

[0042] Specifically, step S20 specifically includes step S21, step S22, and step S23:

[0043] Step S21. Construct an objective function based on vehicle operating income, charging station operating costs, and charging station fixed costs;

[0044] Specifically, the objective function is:

[0045]

[0046] Specifically, Z is the operating net profit; C op is the charging station operating cost; C fix is the charging station fixed cost; p u is the payment fee of user u; u is the user index; U is the set of users.

[0047] Specifically, step S21 specifically includes step S211, step S212, step S213, step S214, step S215, step S216, step S217, step S218, step S219, step S2110, step S2111, step S2112, and step S2113:

[0048] Step S211. Obtain the charging time, charging location, and corresponding charging amount of the vehicle during operation;

[0049] Step S212. Determine the charging unit price of the charging station where the vehicle is located based on the charging time and charging location;

[0050] Specifically, based on the charging location and charging time during vehicle operation, the charging station where the vehicle is located and the corresponding charging unit price at the time of charging are determined.

[0051] Step S213. Calculate the product of the charging unit price and the corresponding charging quantity, and perform a summation calculation to obtain the total daytime charging cost.

[0052] Step S214. Calculate the sum of all charging quantities to obtain the total daytime charging quantity.

[0053] Step S215. Obtain the vehicle battery capacity, the battery power at the end of vehicle operation, and the total energy consumption during vehicle night dispatching, and calculate to obtain the total vehicle night charging quantity.

[0054] Specifically, after the vehicle completes daytime operation, all vehicles will return to the charging station in the current area for charging, and the fully charged vehicles will be relocated to the assigned area for daytime operation. To ensure that the large-scale directional movement of vehicles does not cause road congestion, it is selected to be carried out when the traffic flow is lower than a certain condition. Therefore, the total vehicle night charging quantity is the sum of the charging quantity required for the vehicle to return to the charging station after completing the last order and the energy consumed during the night relocation process.

[0055] Specifically, step S215 specifically includes step S2151, step S2152, step S2153, step S2154, step S2155, step S2156, and step S2157:

[0056] Step S2151. Obtain the unit energy consumption cost, battery capacity, and the battery power at the end of vehicle operation for the vehicles migrating at night between operating areas.

[0057] Step S2152. Based on the operating area where the vehicle is located at the end of operation, determine the total number of vehicles that need to be transferred out and the total number of vehicles that need to be received within each operating area, and use them as the first quantity and the second quantity respectively.

[0058] Step S2153. Determine the minimum value from the first quantity and the second quantity as the target quantity.

[0059] Step S2154. Calculate the product of the target quantity and the unit energy consumption cost to obtain the sixth result.

[0060] Step S2155. Calculate the difference between the set threshold and the battery power at the end of vehicle operation to obtain the seventh result.

[0061] Step S2156. Calculate the product of the seventh result and the battery capacity to obtain the eighth result.

[0062] Step S2157. Calculate the sum of the eighth result and the sixth result to obtain the total vehicle night charging quantity.

[0063] Specifically, the formula for the total night charging amount of the vehicle is:

[0064]

[0065] Among them, TC night is the total night charging amount of the vehicle; cb h is the battery capacity of the vehicle h; SOC h (τ end ) is the power of the vehicle h at time t end ; t end is the end time of vehicle operation; TC rel is the total energy consumption cost of the night-shifted vehicles between operating regions; h is the vehicle index; H is the vehicle set;

[0066] In this application, since the vehicles are homogeneous and each vehicle does not have a fixed initial charging station, the night vehicle relocation problem can essentially be regarded as a balanced transportation problem.

[0067] The number of vehicles to be dispatched from region m and the number of vehicles to be received in region n are represented by the following formula:

[0068]

[0069] Among them, a m is the number of vehicles to be dispatched from region m; b n is the number of vehicles that region n needs to receive; is the number of vehicles in region m after the daytime operation period; is the initial number of vehicles in region m; is the number of vehicles in region n after the daytime operation period; is the initial number of vehicles in region n.

[0070] Use x mn to represent the number of vehicles dispatched from region m to region n, and use w mn to represent the energy consumption cost of dispatching from region m to region n. In order to minimize the total energy consumption cost of the night-shifted vehicles, it is necessary to minimize the energy consumption of the night dispatching. The corresponding objective function is:

[0071] minTC rel = w mn *x mn

[0072] Among them, TC rel is the total energy consumption cost of the night-shifted vehicles between operating regions; w mn is the energy consumption cost of dispatching from region m to region n; x mn is the number of vehicles dispatched from region m to region n;

[0073] The corresponding constraint functions include: indicating that the number of vehicles scheduled in area m is equal to the number of vehicles to be transferred out of area m, where Z1 = {a1, a2, a3... a m}, Z1 is the set of areas for re-transfer, and a m is the number of vehicles to be transferred out of area m; indicating that the number of vehicles scheduled to area n is equal to the number of vehicles to be received in area n, where Z2 = {b1, b2, b3... b n}, Z2 is the set of areas to receive vehicles, and b n is the number of vehicles to be received in area n.

[0074] Step S216. Calculate the sum of the preset unit battery degradation cost and the night charging unit price to obtain a first result;

[0075] Step S217. Calculate the product of the first result and the total night charging amount of the vehicle to obtain a second result;

[0076] Step S218. Calculate the product of the unit battery degradation cost and the total day charging amount to obtain a third result;

[0077] Step S219. Calculate the sum of the total day charging cost, the second result, and the third result to obtain the charging station operation cost;

[0078] Specifically, the charging station operation cost calculation formula is:

[0079]

[0080] where C op is the charging station operation cost; TCC i is the total day charging cost of charging station i; c bd is the unit battery degradation cost; TC i is the total day charging amount of charging station i; TC night is the total night charging amount; c nc is the night charging unit price; i is the charging station index; S is the set of charging stations.

[0081] Step S2110. Obtain the number of charging station parking spaces, the number of vehicles, the unit parking space cost, and the unit vehicle cost;

[0082] Step S2111. Calculate the product of the number of charging station parking spaces and the unit parking space cost to obtain a fourth result;

[0083] Step S2112. Calculate the product of the number of vehicles and the unit vehicle cost to obtain a fifth result;

[0084] Step S2113. Calculate the sum of the fourth result and the fifth result to obtain the fixed cost of the charging station;

[0085] Specifically, the calculation formula for the fixed cost of the charging station is:

[0086]

[0087] where, C fix is the fixed cost of the charging station; c fs is the cost per vehicle; FS is the number of vehicles; c cs is the cost per parking space; cs i is the number of parking spaces of charging station i; i is the charging station index; S is the set of charging stations.

[0088] Step S22. Construct constraint functions based on the basic parameters to obtain multiple objective constraint functions;

[0089] Specifically, Step S22 specifically includes Step S221, Step S222, and Step S223:

[0090] Step S221. Construct multiple first constraint functions based on the operation price of the vehicle position and the preset price threshold range of each operation area;

[0091] Step S222. Construct multiple second constraint functions based on the charging upper and lower limits of each charging station and the preset charging range;

[0092] Step S223. Obtain multiple objective constraint functions based on multiple first constraint functions and multiple second constraint functions;

[0093] Specifically, the operation price at any moment needs to be within a certain range, and the corresponding constraint function expression is as follows:

[0094] pr min ≤pr(t)≤pr max

[0095] where, pr(t) is the unit operation price at time t; pr min is the lower limit of the unit operation price; pr max is the upper limit of the unit operation price.

[0096] The upper and lower limits of the charging range should be within a certain range, and the corresponding constraint function expression is as follows:

[0097]

[0098] where, SOC min is the lower limit of battery charging; SOC max is the upper limit of battery charging; is the lower limit of the charging range in area j at time t; is the upper limit of the charging range for area j at time t.

[0099] Under normal circumstances, it is considered that the upper and lower limits of the set charging range are integers, which is convenient for model calculation. The corresponding constraint function expressions are as follows:

[0100]

[0101] Among them, is the lower limit of the charging range for area j at time t; is the upper limit of the charging range for area j at time t; Z + is a positive integer.

[0102] Step S23. Based on the objective function and multiple objective constraint functions, construct an objective optimization model;

[0103] Specifically, the objective function and multiple constraint functions together constitute the objective optimization model.

[0104] Step S30. Based on the constraint functions preset in the goal programming model, adjust the basic parameters to obtain the target parameters, where the target parameters are the parameters that satisfy each constraint function in the goal programming model;

[0105] Step S40. Correspondingly adjust the charging strategy and pricing strategy based on the target parameters;

[0106] Specifically, in this application, the Alternating Synchronous Perturbation Stochastic Approximation Genetic Algorithm (ASPSA-GA) is used to solve the above objective optimization model, the Synchronous Perturbation Stochastic Approximation Algorithm is used to optimize the pricing strategy, and the Genetic Algorithm is used to optimize the charging threshold of the charging station, allowing the two processes to alternate, so as to obtain the optimal strategy in different time periods and maximize the benefits.
