[0047] The following further elaborates on the detailed embodiments of the present invention with reference to the accompanying drawings.

[0048] In the existing dispatching system, the grid physical model and the market economic model in the medium- and long-term power trading system are independent of each other, and there is no strict correlation between the two models. Power spot trading needs to be based on the grid physical model and introduce the power trading economic model, so that the power trading results based on the economic model can truly reflect the constraints of the grid physical characteristics and ensure that the trading results are implemented in the grid dispatching operation. The spot economic model synchronization method applicable to power spot trading proposed by the present invention can establish a spot economic model applicable to spot trading according to the medium- and long-term economic model and the grid physical model, support the comparison, update, maintenance, and modification of the model, and ensure the establishment of the data mapping relationship between the two types of models.

[0049] Embodiment 1:

[0050] A schematic flow chart of a method applicable to power spot trading data provided by the present invention is as Figure 1 shown, including:

[0051] Step 1: Synchronize the spot economic model based on the grid physical model obtained from the dispatching system on the dispatching side;

[0052] Step 2: Obtain the medium- and long-term economic model based on the medium- and long-term power trading system on the trading side;

[0053] Step 3: Compare the spot economic model and the medium- and long-term economic model to obtain the records to be edited;

[0054] Step 4: Update the spot economic model based on the records to be edited.

[0055] The specific mechanism of an economic model data synchronization method applicable to electricity spot trading is as follows:

[0056] Step 101: Obtain the grid physical model from the dispatching system on the dispatching side, including physical unit models, physical load models, transformer models, and line models;

[0057] Step 102: Generate spot load node models based on physical load orientation, line orientation, and transformer models, with their numbers automatically generated according to the physical numbers of the corresponding devices, and generate spot tie-line models based on line models, with their numbers automatically generated according to the physical numbers of the corresponding lines;

[0058] In this embodiment, "generate" means first emptying all target model tables and obtaining records from the outside to form a new model; that is, in Step 102, when performing data synchronization, the spot load node model is regenerated.

[0059] Step 103: Obtain the medium- and long-term economic model except for economic units from the medium- and long-term power trading system on the trading side, including power plant models, power generation group models, and power user models, and update the power plant, power user, and power generation group models in the spot; among them, the power plant models, power generation group models, and power user models in the medium- and long-term economic model can also be called power plant information, power generation group information, and power user information, respectively;

[0060] In this embodiment, "update" means not emptying the original model, comparing the target model table with external data, adding new records, deleting records that need to be deleted, and updating local information for the same records. Specifically, for the generation of the initial model, it is equivalent to all records being new.

[0061] Step 104: Obtain the medium- and long-term economic unit model from the medium- and long-term power trading system on the trading side, compare and analyze it with the spot economic unit model, check whether the parameter changes are reasonable and whether there are new units, etc., and update the spot economic unit model;

[0062] Step 104 uses a model comparison module to read the medium- and long-term trading economic model and the spot economic model, obtain information on economic units, power plants, power generation groups, and power users, and compare, based on the spot model, which records are newly added, which records are deleted, and which record field values are modified in the medium- and long-term economic model. The specific steps are as follows:

[0063] Step 104-1: Read the corresponding table contents in the medium- and long-term model and the spot model in sequence according to the configured table names to be compared;

[0064] Step 104-2: Read the keyword information of the corresponding table in the spot model to form a spot model record index. Similarly, read the keyword information of the corresponding table in the medium- and long-term model to form a medium- and long-term model record index;

[0065] Step 104-3: Read and compare the record index of the medium- and long-term model according to the spot model record index to obtain the records that need to be added and the records that need to be deleted, and display the comparison results on the interface;

[0066] Step 104-4: For the records with the same index, the results of the records need to be parsed, and the changes in the field values of each field are compared, and the field value comparison results are displayed on the interface.

[0067] In steps 103 and 104, when updating the spot economic model, the model update module obtains the medium- and long-term economic model from the trading side and the grid physical model from the dispatching side, and integrates the two models into the spot economic model used by the spot trading technical support system. The main update process is as follows:

[0068] 1) Read the comparison result table of the model comparison module, obtain the records that need to be added, deleted, and modified in each model table, and generate corresponding execution statements;

[0069] 2) Read the grid physical load, line, and transformer models. Determine whether it belongs to a load node according to the endpoints at both ends of the device, and generate a spot load node model update statement with the endpoints that can be equivalent to the load node. Its economic number is automatically generated according to the physical number of the corresponding device;

[0070] 3) Read the grid line model. Determine whether it belongs to an inter-provincial or inter-regional tie line according to the geographical regions to which the endpoints at both ends of the line belong, and generate a spot tie line model update statement with the line endpoints that belong to the tie line. Its economic number is automatically generated according to the physical numbers of the endpoints of the corresponding line;

[0071] 4) Execute the spot model update statements formed in the above steps in the corresponding database. If the execution of the updated statement fails, report an error and let professionals troubleshoot. The updated data is cancelled and not committed and does not take effect.

[0072] Step 105: Through the model management module, view the updated spot economic model and adjust the unreasonable parameters;

[0073] Step 106: If new units are added, the corresponding relationship between the economic model and the physical model needs to be maintained. Set the corresponding physical device numbers for the newly added units through the model management module, establish and maintain the mapping relationship between the economic units and the physical units, and set the values of the domains unique to the spot trading;

[0074] Step 107: If a new electricity user is added, the information of the power user's access point is required. The model management module sets the corresponding physical load node number for the newly added electricity user, and establishes and maintains the mapping relationship between the economic electricity user and the grid physical node.

[0075] Embodiment 2:

[0076] Based on the same inventive concept, the present invention also provides a synchronization system applicable to power spot trading data. Since the principles of these devices for solving technical problems are similar to those of the spot economic model synchronization method applicable to power spot trading, the repeated parts will not be elaborated here.

[0077] The system structure is as Figure 3 shown, including: a model comparison module and a model update module; the model comparison module is used to obtain the medium- and long-term economic model based on the medium- and long-term power trading system on the trading side, and compare the spot economic model with the medium- and long-term economic model to obtain the records that need to be edited; the model update module is used to synchronize the spot economic model based on the grid physical model obtained from the dispatching system on the dispatching side, and is also used to update the spot economic model based on the records that need to be edited.

[0078] The model management module is used to view and maintain the spot economic model.

[0079] The functions and operation processes of the three modules will be specifically described below.

[0080] Model comparison module

[0081] The model comparison module reads the medium- and long-term trading economic model and the spot economic model, obtains information on economic units, power plants, power generation groups, and electricity users, and takes the spot model as the benchmark to compare which records are newly added, which records are deleted, and which record field values are modified in the medium- and long-term economic model. The specific steps are as follows:

[0082] Step 201: Read the corresponding table contents in the medium- and long-term model and the spot model in sequence according to the configured table names to be compared;

[0083] Step 202: Read the keyword information of the corresponding table in the spot model to form a spot model record index, and similarly read the keyword information of the corresponding table in the medium- and long-term model to form a medium- and long-term model record index;

[0084] Step 203: Read and compare the record index of the medium- and long-term model according to the spot model record index to obtain which records need to be added and which records need to be deleted, and display the comparison results on the interface;

[0085] Step 204: For records with the same index, it is necessary to parse the results of the records, compare the changes in the field values of each field, and display the field value comparison results on the interface.

[0086] Model update module

[0087] The model update module obtains the medium- and long-term economic model from the trading side and the power grid physical model from the dispatching side, and integrates the two models into the spot economic model used by the spot trading technical support system.

Its economic number is automatically generated according to the physical number of the corresponding device;

[0090] Step 213: Read the power grid line model. Determine whether it belongs to an inter-provincial or inter-regional tie line based on the geographical regions to which the endpoints at both ends of the line belong, and generate a spot tie line model update statement using the line endpoints that belong to the tie line. Its economic number is automatically generated according to the physical numbers of the endpoints of the corresponding line;

[0091] Step 214: Execute the spot model update statements formed in the above steps in the corresponding database. If the execution of the updated statement fails, report an error and let professionals troubleshoot. The updated data is cancelled and not submitted and does not take effect.

[0098] 4) Support fuzzy retrieval of units, loads, and tie lines by Chinese name;

[0099] 5) Support modifying the domain values of a single model record;

[0100] 6) When adding an economic unit, it is necessary to set its physical code through the model management module and maintain the mapping relationship between the economic unit and the physical unit;

[0101] 7) When adding a power user, it is necessary to set the network connection node through the model management module, and establish and maintain the mapping relationship between the power user and the physical load node of the power grid.

[0102] Through the synchronization method for power spot trading data provided by the present invention, multi-dimensional aggregation and display of the spot economic model are realized, and the model records are maintained and managed.
