[0027] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0028] In this embodiment, a method for scheduling a mobile energy storage system is provided. This embodiment uses the method applied to a computer device as an example for illustration. It is understandable that the method can also be applied to a server, and can also be applied to a system including a computer device and a server, and is implemented through the interaction between the computer device and the server.

[0029] The mobile energy storage system in this embodiment includes units such as vehicles, phase change cold storage materials, heat pumps, and fans. The phase change materials in the mobile energy storage system have the characteristic of releasing a large amount of cold energy at the phase change temperature point. By utilizing this characteristic and combining it with the space transfer of the vehicles of the mobile energy storage system, the cold energy needs of different locations can be met. The power side of the mobile energy storage system obtains electrical energy and converts the electrical energy into cold energy for refrigeration by controlling the heat pump on its power side, so that the phase change material can store energy and store cold; the thermal side of the mobile energy storage system can flexibly adjust the fan speed to speed up the release of cold from the phase change material, thereby meeting the cold energy needs of the location.

[0030] Figure 1 A flow chart of a mobile energy storage system scheduling method provided in an embodiment of the present application is provided. The method is applied to a computer device or a server. In one embodiment, Figure 1 As shown, the following steps are included:

[0031] S101, obtaining cooling and electricity data corresponding to different locations.

[0032] In this embodiment, the cooling power data may be cooling load data for different buildings, and the cooling load data is determined based on the intermittent cooling demand at multiple different locations, such as the locations of multiple different buildings. Alternatively, when the cooling power data is a predicted value of wind power abandonment at a distributed wind turbine, and the cooling power data is a predicted value of wind power abandonment at a distributed wind turbine, the location in S101 refers to the wind abandonment location, such as the location of the distributed wind turbine. Alternatively, when the cooling power data is a predicted value of solar power abandonment at a photovoltaic owner, and the cooling power data is a predicted value of solar power abandonment at a photovoltaic owner, the location in S101 refers to the solar abandonment location, such as the location of the photovoltaic owner.

[0033] It should be noted that the intermittent cooling demand of multiple different buildings can be investigated to analyze and determine the cooling load data of different buildings. At the same time, the predicted values of abandoned wind power and abandoned solar power are obtained from the owners of distributed wind turbines and photovoltaics. The cooling power data formula (1) at location i is defined as D i :

[0034]

[0035] Wherein, i is an integer greater than zero; T is a preset scheduling period, for example, T can be set to 24 hours; t is an integer greater than or equal to 1 and less than or equal to 24 within the preset scheduling period; and They represent the cooling load power, wind curtailment power and solar curtailment power at location i in time period t respectively; D i At least and In one of the columns, the same location may have both wind power and solar power curtailment.

[0036] For example, if location 1 is a building with cooling energy demand, then:

[0037]

[0038] S102: Constructing constraints for the mobile energy storage system based on the cold power data corresponding to different locations.

[0039] In this embodiment, the constraints of the mobile energy storage system may include some or all of the following: spatial transfer constraints, energy storage constraints, consumption constraints, and cooling energy constraints. It should be noted that other constraints may be employed or added to construct the constraints of the mobile energy storage system, and this embodiment does not limit the specific constraints.

[0040] S103: Construct a mobile energy storage scheduling model based on the constraints.

[0041] In this embodiment, a mobile energy storage scheduling model is constructed, and the mobile energy storage scheduling model is shown in formulas (2) to (4). Among them, formula (2) represents the scheduling target of the mobile energy storage system, that is, minimizing the daily power supply cost, formula (3) indicates that the spatial location of the mobile energy storage system must return to the initial location at the end of scheduling, and formula (4) indicates that the energy storage of the mobile energy storage system must return to the initial energy storage at the end of scheduling.

For example, the value is 120 yuan; represents the working power of the heat pump in the mobile energy storage system during time period t; Represents the cooling power of the mobile energy storage system at location i and in time period t; Boolean type B ii,t Refers to the spatial position of the mobile energy storage system in time period t. When its value is 1, it means the vehicle is at location i; B ii,0 Refers to the spatial position of the mobile energy storage system at the beginning of scheduling; B ii,T Refers to the spatial location of the mobile energy storage system at the end of dispatch; Represents the initial energy storage of the mobile energy storage system at the beginning of dispatch; Represents the energy storage of the mobile energy storage system at the end of scheduling.

[0046] S104 , determining a scheduling decision for the mobile energy storage system according to the mobile energy storage scheduling model and the constraint conditions, so as to schedule the mobile energy storage system based on the scheduling decision.

[0047] In this embodiment, some formulas of the mobile energy storage scheduling model require linearization, so the mobile energy storage scheduling model is treated as a classic mixed-integer linear programming problem. This embodiment uses the commercial solver Gurobi to solve the mobile energy storage scheduling model and constraints and output the solution results to determine the scheduling decision of the mobile energy storage system. It should be noted that other solvers or solution methods can also be used, and this embodiment does not limit the solution method.

[0048] The mobile energy storage system scheduling method provided in this embodiment obtains the cold electricity data corresponding to different locations; constructs the constraints of the mobile energy storage system based on the cold electricity data corresponding to different locations, and constructs a mobile energy storage scheduling model based on the constraints, and then determines the scheduling decision of the mobile energy storage system based on the mobile energy storage scheduling model and the constraints, so as to schedule the mobile energy storage system based on the scheduling decision. Since the embodiment of the present application can determine the scheduling decision of the mobile energy storage system based on the mobile energy storage scheduling model and the constraints, so as to schedule the mobile energy storage system based on the scheduling decision, the mobile energy storage system can be fully utilized, so that the mobile energy storage system can release cold energy at different locations where cold energy is needed, without the need to deploy fixed refrigeration tools at different locations, thereby avoiding the waste of fixed refrigeration tools.

[0049] Optionally, the above S102 may be implemented in the following manner:

[0050] Based on the corresponding cold power data of different locations, the spatial transfer constraints, absorption constraints, cold energy constraints and energy storage constraints of the mobile energy storage system are constructed;

[0051] Among them, the constraints include spatial transfer constraints, absorption constraints, cold energy constraints and energy storage constraints.

[0052] In this embodiment, to ensure the smooth operation of the mobile energy storage system, the mobile energy storage system must simultaneously meet spatial transfer constraints, absorption constraints, cooling energy constraints, and energy storage constraints. By establishing the constraints of the mobile energy storage system, a scheduling decision for the mobile energy storage system is determined. The mobile energy storage system is then scheduled based on the scheduling decision, achieving full utilization of the mobile energy storage system and improving its utilization rate.

[0053] Optionally, the above-mentioned spatial transfer constraints can be implemented as follows:

[0054] The spatial transfer constraint conditions include the correspondence between different spatial positions of the mobile energy storage system and different time periods, the first spatial transfer constraint condition, the second spatial transfer constraint condition, and the travel time of the vehicle of the mobile energy storage system on the route segment being greater than or equal to the preset transfer time corresponding to the route segment;

[0055] The first spatial transfer constraint condition includes that when the vehicle is at the first location in the first time period, it is at the first location or heading to the second location in the second time period. The second spatial transfer constraint condition includes that when the vehicle is at the route segment from the first location to the second location in the first time period, the vehicle is on the route segment or arrives at the second location in the second time period. The second time period is the next time period of the first time period.

[0056] In this embodiment, the spatial transfer constraints for constructing the mobile energy storage system are shown in formulas (5) to (8). The first time period is time period t, and the second time period is time period t+1. Formula (5) indicates that the mobile energy storage system has one and only one spatial location in any time period t. Formula (6) indicates that if a vehicle is at location i during time period t, it can only be at location i (i=j) or on its way to location j (i≠j) during the next time period t+1. Formula (7) indicates that if a vehicle is on the road from location i to location j during time period t, it can either still be on the road or arrive at location j during the next time period t+1. Formula (8) indicates that the travel time of a vehicle from location i to location j is greater than or equal to the preset transfer time corresponding to the route segment from location i to location j.

[0057] Σ ij B ij,t =1 (5)

[0058] Σ j B ij,t+1 ≥B ij,t (6)

[0059]

[0060]

[0061] Where j is an integer greater than or equal to 1; Boolean B ij,t Refers to the spatial location of the mobile energy storage system. When its value is 1, it means that the vehicle is on the road from location i to location j, and when its value is 0, it means that the vehicle is not on the road. ij It represents the time it takes for a vehicle to travel from location i to location j. It is an integer greater than or equal to 1 and less than or equal to 24. When i≠j, T ij =1; the constrained transfer time is the average time it takes for a vehicle to travel from location i to location j, which can be obtained through surveys and other means.

[0062] In this embodiment, the spatial constraint conditions of the mobile energy storage system are established to determine the scheduling decision of the mobile energy storage system, thereby improving resource utilization.

[0063] Optionally, the above-mentioned absorption constraints can be implemented as follows:

[0064] The operating power of the mobile energy storage system in any time period is greater than or equal to zero and less than or equal to the sum of the first predicted value and the second predicted value in the corresponding time period; the operating power of the mobile energy storage system in any time period is greater than or equal to zero and less than or equal to the rated operating power of the mobile energy storage system; the cooling power of the mobile energy storage system in any time period is equal to the operating power of the mobile energy storage system in the corresponding time period multiplied by the cooling efficiency of the mobile energy storage system;

[0065] Among them, the first predicted value is the predicted value of the wind power abandoned at the wind abandonment location, and the second predicted value is the predicted value of the solar power abandoned at the solar power abandonment location. In this embodiment, the vehicle of the mobile energy storage system goes to the wind abandonment location and the solar power abandonment location to consume the electric energy to be discarded. By absorbing this part of the electric energy, the heat pump of the mobile energy storage system is controlled to convert the electric energy into cold energy for refrigeration. Therefore, the absorption constraint conditions of the mobile energy storage system are shown in formulas (9) to (11). Among them, formula (9) indicates that the working power of the heat pump of the mobile energy storage system cannot be greater than the sum of the wind power abandoned and the abandonment rate, formula (10) indicates that the working power of the heat pump of the mobile energy storage system cannot be greater than the rated working power of the mobile energy storage system, and formula (11) represents the cooling power of the heat pump.

[0066]

[0067]

[0068]

[0069] Where, Indicates the rated operating power of the heat pump in the mobile energy storage system. It is set according to the actual situation, for example, it is set to 900kW; represents the cooling power of the mobile energy storage system in time period t; η is the cooling efficiency of the mobile energy storage system, which represents the conversion rate of the heat pump in the mobile energy storage system from the absorbed electrical energy to cooling energy. It is set according to the actual working conditions of the heat pump, for example, to 2.6.

[0070] In this embodiment, by establishing absorption constraints for the mobile energy storage system and then determining the dispatching decision for the mobile energy storage system based on the absorption constraints, the mobile energy storage system of this embodiment can absorb the abandoned wind power at the abandoned wind power location and the abandoned solar power at the abandoned solar power location. This makes use of the previously wasted electric energy resources, thereby improving the utilization rate of the abandoned wind power and abandoned solar power and other electric energy resources. It should be noted that while this embodiment absorbs the wasted electric energy from abandoned wind power and abandoned solar power, it can also absorb other forms of electric energy, such as the wasted electric energy resources from hydropower generation. This embodiment does not limit the specific electric energy resources absorbed.

[0071] Optionally, the above cold energy constraint condition can be achieved by:

[0072] The cooling power of the mobile energy storage system in any time period is greater than or equal to zero and less than or equal to the rated working power of the mobile energy storage system, and the cooling power of the mobile energy storage system in any time period is equal to the cooling load power of the corresponding time period.

[0073] In this embodiment, the mobile energy storage system can release stored energy to meet the cooling load energy demand. The corresponding cooling energy constraints are shown in formulas (12) and (13). Formula (12) indicates that the cooling power of the mobile energy storage system must be less than the rated power, and formula (13) indicates that the cooling capacity of the mobile energy storage system must meet the cooling load demand. The cooling power of the mobile energy storage system in any time period is equal to the cooling load power in the corresponding time period.

[0074]

[0075]

[0076] Where, Indicates the rated cooling power of the mobile energy storage system. It is set according to the actual situation, for example, it is set to 900kW.

[0077] In this embodiment, the cold energy constraint condition of the mobile energy storage system is established to determine the scheduling decision of the mobile energy storage system, thereby improving resource utilization.

[0078] Optionally, the above energy storage constraints can be implemented in the following ways:

[0079] The energy storage capacity of the mobile energy storage system in the first time period is determined based on the energy storage capacity of the third time period, the energy storage capacity of the first time period, and the release capacity. The energy storage capacity of the mobile energy storage system in the first time period is greater than or equal to zero and less than or equal to the maximum energy storage capacity of the mobile energy storage system. The third time period is a time period before the first time period.

[0080] In this embodiment, the energy storage constraint conditions for constructing the mobile energy storage system are shown in formulas (14) and (15). Wherein, the third time period is time period t-1. Formula (14) indicates that the energy storage capacity of the mobile energy storage system in time period t is determined by the energy storage capacity in time period t-1 and the storage capacity and release capacity in time period t. Formula (15) indicates the energy storage capacity constraint of the mobile energy storage system. The energy storage capacity of the mobile energy storage system in time period t is greater than or equal to zero and less than or equal to the maximum energy storage capacity of the mobile energy storage system.

[0081]

[0082]

[0083] Where, represents the energy storage of the mobile energy storage system in time period t, Indicates the maximum energy storage capacity of the mobile energy storage system.

[0084] In this embodiment, energy storage constraints of the mobile energy storage system are established to determine the scheduling decision of the mobile energy storage system, thereby improving resource utilization.

[0085] Figure 2 A flow chart of a method for determining a scheduling decision for a mobile energy storage system provided in an embodiment of the present application is provided. Figure 2 This embodiment relates to an optional implementation method for determining the scheduling decision of a mobile energy storage system. Based on the above embodiment, the above S104, based on the mobile energy storage scheduling model and the constraints, determines the scheduling decision of the mobile energy storage system, including the following steps:

[0086] S201. Determine the energy change and spatial position change corresponding to the mobile energy storage system based on the mobile energy storage scheduling model and constraints. The energy change includes the cold energy demand and energy release at different locations during spatial transfer within a preset scheduling period, and the changes in the storage power and release power of the mobile energy storage system during the preset scheduling period. The spatial position change refers to the change in the spatial position of the mobile energy storage system during spatial transfer within the preset scheduling period.

[0087] In this embodiment, formula (8) is linearized into formula (16), and combined with the parameters such as the electricity price, cooling price, and hourly space transfer cost of the mobile energy storage system introduced in the above example, and the commercial solver Gurobi is called to substitute all formulas (1) to (16) except formula (8) for solution.

[0088]

[0089] The solution result is output. For example, the solution result is that the daily operating cost of the mobile energy storage system is -2112 yuan, of which the electricity purchase cost is 1205 yuan, the space transfer cost is 600 yuan, and the cooling income is 3917 yuan. Therefore, the mobile energy storage system of this embodiment can operate well.

[0090] Figure 3 The changes of cooling load power, wind power abandonment and solar power abandonment at different locations over time in the embodiment of this application are as follows: Figure 4 The changes in the spatial position of the mobile energy storage system and the changes in the energy storage power over time in the embodiment of the present application are as follows: Figure 5 The energy storage power and energy release power of the mobile energy storage system in the embodiment of the present application change over time, such as Figures 3 to 5As shown, the energy storage power is, for example, the cooling power, and the energy release power is, for example, the cooling power. Figure 3 The solid line in the figure represents the cooling load demand at location 1 during the time period t = 3 to 10. Figure 3 The dotted line in the figure represents the cooling load data demand at location 2 during the time period from t 15 to 22. The cooling load data is the cooling load power. Figure 3 The solid line 301 with dots in the graph represents the wind power or solar power curtailment at location 3 during the time period t = 1 to 5. Figure 3 The solid line 302 with dots in the graph represents the wind power or solar power curtailment during the time period t=10-17. Figure 4 The solid line with dots in the figure represents the spatial position of the vehicle of the mobile energy storage system. Figure 3 and Figure 4 It can be seen that the vehicle of the mobile energy storage system is at location 3 during the time period when t is equal to 2 and the time period when t is 11-14. The mobile energy storage system absorbs the abandoned wind power or abandoned solar power at location 3 and controls the heat pump cooling on the power side of the mobile energy storage system so that the phase change material stores energy. When the spatial position of the vehicle of the mobile energy storage system is location 1 and during the time period when t is 4-9, the thermal side of the mobile energy storage system flexibly adjusts the fan speed to accelerate the release of cold from the phase change material and releases cold energy to location 1. When the spatial position of the vehicle of the mobile energy storage system is location 2 and during the time period when t is 16-22, the thermal side of the mobile energy storage system flexibly adjusts the fan speed to accelerate the release of cold from the phase change material and releases cold energy to location 2. Figure 4 The dotted line in the figure shows how the energy storage situation of the mobile energy storage system changes at different times and locations. Figure 5 The dotted line in the figure represents the cold storage power of the mobile energy storage system. The spatial position of the mobile energy storage system vehicle is at location 3 during the time period t = 2 and the time period t = 11-14. Therefore, the mobile energy storage system has cold storage power during the time period t = 2 and the time period t = 11-14, and the cold storage power is in the growth stage. Figure 5 The solid line in the figure represents the cooling power of the mobile energy storage system. The vehicle of the mobile energy storage system is located at location 1 during the time period t 4 to 9 and at location 2 during the time period t 16 to 22. Therefore, the mobile energy storage system performs cooling based on the cooling power of the corresponding time period during the time period t 4 to 9 and the time period t 16 to 22. Figures 3 to 5It can be seen that the mobile energy storage system consumes electricity at location 3 where wind power or solar power is curtailed. The heat pump on the power side uses cooling to store cold in the phase change material. The thermal side of the mobile energy storage system flexibly adjusts the fan speed to accelerate the release of cold from the phase change material, thereby meeting the cooling needs of locations 1 and 2. Only one device can meet the intermittent cooling needs of different locations on a time-sharing basis. The energy storage power, cold storage power, and cold release power of the mobile energy storage system also meet the operating requirements, achieving full utilization of the mobile energy storage system and resources such as curtailed wind power and curtailed solar power, avoiding waste of resources such as curtailed wind power and curtailed solar power.

[0091] S202: Determine a scheduling decision for the mobile energy storage system based on energy changes and spatial position changes corresponding to the mobile energy storage system.

[0092] In this embodiment, based on the above-mentioned solution results, the scheduling decision of the mobile energy storage system can be determined, so as to formulate a scheduling plan for the mobile energy storage system to meet the intermittent cooling demand of different locations and absorb the abandoned wind and solar power. This embodiment determines the energy change and spatial position change corresponding to the mobile energy storage system according to the mobile energy storage scheduling model and constraints, and determines the scheduling decision of the mobile energy storage system according to the energy change and spatial position change corresponding to the mobile energy storage system. Since the mobile energy storage system of this embodiment controls the heat pump cooling on the power side to store energy in the phase change material, and flexibly adjusts the fan speed on the thermal side to accelerate the release of cold from the phase change material to meet the intermittent cooling demand of different locations, only one device can meet the intermittent cooling demand of different locations on a time-sharing basis, and can absorb the abandoned solar and wind power, thereby achieving efficient resource utilization and improving resource utilization.
