[0055] In order to make the purpose, technical scheme and advantages of the present application clearer, the present application is further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.
[0056] In remote areas, in order to meet the living requirements of local residents, the electricity demand and heat demand of local residents need to be met.
[0057] Considering the small electricity demand, large investment cost of laying lines and other problems, some remote areas (such as grasslands or plateaus) in China are not connected to the large power grid. The local villages will use diesel generators to generate electricity, but the cost of power generation is relatively high.
[0058] For the heat demand of residents, an air conditioning system is usually configured to provide heat, and a diesel generator system is also needed to provide power to ensure the operation of the air conditioning system.
[0059] However, the above-mentioned use of diesel engine power generation to support the user's electricity demand and the normal operation of the air conditioner has high energy supply consumption cost.
[0060] Therefore, the embodiment of the present application provides a mobile energy storage system scheduling method, which can reduce the energy supply consumption cost.
[0061] It should be noted that the mobile energy storage system scheduling method provided by the embodiment of the present application can be a mobile energy storage system scheduling device, which can be implemented by software, hardware or a combination of software and hardware to become part or all of the terminal.
[0062] In the following method embodiment, the terminal is taken as an example to be executed, wherein the terminal can be a personal computer, a notebook computer, a media player, a smart television, a smart phone, a tablet computer and a portable wearable device, etc. It can be understood that the method can also be applied to a server, and can also be applied to a system including a terminal and a server, and is realized through the interaction of the terminal and the server.
[0063] Please refer to Figure 1 which shows a flowchart of a mobile energy storage system scheduling method provided by the embodiment of the present application. As Figure 1 shown, the mobile energy storage system scheduling method can include the following steps:
[0064] Step 101, obtaining demand prediction data corresponding to a plurality of target time points in a preset time period respectively.
[0065] The demand prediction data includes an electric load power demand prediction value, a thermal load power demand prediction value and a mobile energy storage system position transfer time prediction value.
[0066] The mobile energy storage system needs to complete the round trip between the grid side and the village site in the preset time period. The position transfer time prediction value corresponding to a target time point refers to the driving time required from the starting site to the target site starting from the target time point. Optionally, the position transfer time prediction value of the mobile energy storage system includes the driving time prediction value from the grid side site to the village site and the driving time prediction value from the village site to the grid side site.
[0067] Optionally, the length of the preset time period is 1 day or 1 week. The preset time period is divided into a plurality of target time points according to a preset time length, wherein the preset time length can be 1 hour, several hours, several minutes or several tens of minutes, etc. For example, when the length of the preset time period is 1 day, the preset time period is divided into 24 target time points according to 1 hour as the preset time length.
[0068] Optionally, the demand prediction data D is represented as follows:
[0069]
[0070] wherein T is a preset time period, i.e., a scheduling period, and is 24 hours; and respectively represent an electric load power demand prediction value and a thermal load power demand prediction value at a tth target moment, wherein t = 1, 2, … T; and respectively represent a position transition time prediction value of the mobile energy storage system from the power distribution network to the village and from the village to the power distribution network at the tth target moment.
[0071] In step 102, the constraint condition and the scheduling model corresponding to the mobile energy storage system are obtained.
[0072] The constraint condition at least includes a power supply operation constraint condition and a heat supply operation constraint condition of the mobile energy storage system, and the scheduling model is used to represent a scheduling target of the mobile energy storage system in the preset time period.
[0073] Optionally, the power supply operation constraint condition at least includes a charging constraint condition and a discharging constraint condition, etc. The heat supply operation constraint condition at least includes a heat storage constraint condition and a heat release constraint condition, etc.
[0074] Optionally, the scheduling target of the scheduling model is to minimize the length of time for which the diesel engine power generation system is used to generate power in the preset time period. The scheduling model includes an objective function and a constraint condition corresponding to the objective function, and correspondingly, the objective function is a function corresponding to the minimum length of time for which the diesel engine power generation system is used to generate power in the preset time period.
[0075] In step 103, when the demand prediction data and the constraint condition both satisfy the scheduling target, the supply data corresponding to the demand prediction data is determined according to the demand prediction data and the scheduling model.
[0076] The supply data includes the power generation power of the diesel engine corresponding to each target moment, the actual discharging power and the actual charging power of the mobile energy storage system, and the actual heat storage power and the actual heat release power of the mobile energy storage system, etc.
[0077] Optionally, the terminal inputs the demand prediction data and the constraint condition into the scheduling model, solves the calling model, and obtains the supply data. For example, the terminal calls a Gurobi solver to solve the calling model.
[0078] In the aforementioned method for dispatching the mobile energy storage system, demand forecast data corresponding to multiple preset target times, along with the corresponding constraints and dispatch model of the mobile energy storage system, are acquired. When both the demand forecast data and constraints meet the dispatch objectives, the supply data corresponding to the demand forecast data is determined based on the demand forecast data and dispatch model. The demand forecast data includes predicted values for electrical load power demand, thermal load power demand, and the predicted location transfer time of the mobile energy storage system. The constraints include at least power supply and heating operation constraints for the mobile energy storage system. Since a mobile energy storage system is used to meet residents' electricity and heating needs, its consumption cost is lower than that of diesel generators, reducing the cost of meeting energy supply requirements. By determining the final supply data corresponding to the demand forecast data based on the predicted values for electrical load power demand, thermal load power demand, and thermal load power demand, and considering both user electricity and heating needs, the joint dispatch of power supply and heating from the mobile energy storage system is achieved, realizing reasonable dispatch of the mobile energy storage system and significantly reducing operating costs. In addition, the location transfer time prediction value of the mobile energy storage system was also used when determining the supply data corresponding to the final demand forecast data. This fully takes into account the spatial transfer uncertainty of the mobile energy storage system and improves the reliability and accuracy of the scheduling results.

[0082] The historical demand data includes historical electrical load power demand values, historical thermal load power demand values, and historical location transfer times of mobile energy storage systems.
[0083] Optionally, the length of this historical time period is the same as the length of a preset time period. The historical time period is divided according to the preset time period to obtain multiple historical moments. This historical time period is any time period preceding the preset time period in chronological order. For example, this historical time period is a time period whose end point is the start time of the preset time period in chronological order.
[0084] Optionally, a large amount of historical demand data samples are stored in the terminal, and the data samples include historical demand data and time information corresponding to the historical demand data. The historical demand data samples are processed according to the time information corresponding to the historical demand data, and historical demand data corresponding to each historical time in a historical time period is obtained.
[0085] In step 202, demand prediction data corresponding to each target time is obtained according to the historical demand data corresponding to each historical time and a prediction model.
[0086] Optionally, the prediction model includes one of a long short-term memory (LSTM) model, a temporal convolutional network (TCN) model, and a time graph network (TGNs) model.
[0087] The prediction model can be trained by the terminal itself, or the prediction model can be trained by a server and sent to the terminal after training, so as to save the computing resources of the terminal. The terminal inputs the historical demand data corresponding to each historical time into the trained prediction model, and obtains the demand prediction data corresponding to each target time.
[0088] In this embodiment, the demand prediction data corresponding to each target time is obtained according to the historical demand data corresponding to each historical time and the prediction model, and the demand prediction data corresponding to each target time is obtained by prediction based on historical data, thereby improving the accuracy of the demand prediction data.

[0093] In step 302, for each target time, a Monte Carlo sampling model is used to obtain a plurality of demand prediction data corresponding to the demand prediction initial data.
[0094] Optionally, the demand prediction initial data is predicted according to a demand, an interval to which the demand prediction data belongs is determined, and a plurality of data is determined from the interval as the demand prediction data by using a Monte Carlo sampling model.
[0095] The embodiment acquires a plurality of demand prediction data corresponding to the demand prediction initial data by using the Monte Carlo sampling model, determines a plurality of possible demand prediction data by using a statistical analysis method, and improves the accuracy of the dispatching method.

[0097] In step 401, a normal distribution function satisfied by the demand prediction initial data is acquired.
[0098] Optionally, a formula of the normal distribution function satisfied by the demand prediction initial data is as follows:

[0104] At step 402, the normal distribution function and the demand prediction initial data are input into the Monte Carlo sampling model to obtain a plurality of demand prediction data corresponding to the demand prediction initial data.
[0105] Optionally, according to the normal distribution function and the demand prediction initial data, the Monte Carlo sampling model is used to generate a plurality of demand prediction data for each demand prediction initial data. The number of the demand prediction data can be set according to actual conditions. That is, a plurality of scenarios are generated by using the Monte Carlo sampling method to simulate the demand prediction data that can occur.
