Description

Technical Field

[0001] The present application relates to the field of power trading, and specifically to a power trading simulation method, device and medium based on power system operation constraints. Background Art

[0002] The physical grid of the power system is the carrier of power transactions. Without the physical system, transactions will not be possible. The commodity transmission speed of the power system is much higher than that of other commodity markets. The transaction and delivery calculation process and results of the power market are highly correlated, real-time and interactive with the power system operation flow. However, on the one hand, this correlation is invisible. On the other hand, market mechanisms and trading behaviors that do not consider the laws of system operation will destroy the system balance and significantly increase the possibility of system collapse and blackouts.

[0003] The production, transmission and consumption of the power system must be balanced at all times, and the real-time requirements are extremely strict. As a basic industry, its product electricity is closely related to all aspects of the national economy. Once the system load fluctuates or the equipment exceeds the limit, it may cause power outages, system crashes, and cause a series of serious consequences such as equipment damage, economic losses and casualties. The system operation is dangerous, unreachable and irreversible.

[0004] There is no possibility to build and conduct physical experiments in colleges and universities, and students cannot participate in actual transactions. This leads to the fact that the staff who have just entered the industry have strong theoretical ability but poor practical ability. If destructive experiments are conducted using actual systems, the experimental results will destroy the stable operation of the system. System outages not only make it impossible to conduct market electricity transactions, but also cause power outages in the entire region, causing very bad social and economic impacts.

[0005] Therefore, there is an urgent need for a power trading simulation method based on power system operation constraints to fill the gap in the power trading simulation system in the existing technology and enhance the practical operation ability of the staff. Summary of the invention

[0006] In order to solve the above problems, the present application proposes a method, device and medium for simulating power trading based on power system operation constraints, wherein the method includes:

[0007] Based on the role identity and transaction mode selected by the user, a corresponding type of power transaction model is provided to the user; the role identity includes at least one of a power transaction center, a power generation enterprise, a power sales company and a power user; by monitoring the power transaction operation of the user, the transaction data of the user in the current transaction stage is obtained; the operation constraints of the power transaction model are determined, and the operation constraints include system constraints, unit constraints and network constraints; based on the transaction data, the operation constraints and the bidding algorithm, the transaction operations of other roles in the power transaction model in the current transaction stage are simulated to obtain transaction results; the transaction results are returned to the user so that the user can interact with the power transaction model based on the transaction results.

[0008] In one example, based on the transaction data, the operating constraints and the bidding algorithm, the transaction operations of other roles in the power trading model in the current transaction stage are simulated, specifically including: determining that the user is a power trading center role; creating a transaction based on the transaction-related information sent by the user, and the transaction-related information includes transaction number, transaction name, transaction type, transaction start time and transaction end time; after initiating the transaction, obtaining the declared electricity and declared price of other roles from a preset database; based on the bidding algorithm, clearing the declared electricity and declared price of other roles to obtain the winning bid information of the other roles; based on the winning bid information and the operating constraints, performing a security check on the transaction, and the transaction ends after the check passes.

[0010] In one example, before obtaining the transaction data of the user in the current transaction stage by monitoring the user's electricity trading operations, the method also includes: determining that the role identity selected by the user is a power generation enterprise or a power sales company; sending the power generation cost corresponding to the role identity to the user, so that the user can perform electricity trading operations based on the power generation cost; after obtaining the transaction data of the user in the current transaction stage by monitoring the user's electricity trading operations, the method also includes: determining that there are other users whose role identities are power generation enterprises or power sales companies; obtaining the historical clearing prices of all users in the simulation process, and processing the historical clearing prices to obtain the historical clearing price range; obtaining the current declared prices of all users, and determining the average declared price of the current transaction based on the current declared prices; determining malicious bidding users among the other users based on the average declared price and the historical clearing price range; and clearing the current declared prices corresponding to the malicious bidding users from the transaction data.

[0011] In one example, returning the transaction result to the user specifically includes: determining the winning power generation enterprise role, power sales company role and power user role based on the transaction result; respectively obtaining the declared electricity volume and declared price corresponding to the power generation enterprise role, the power sales company role and the power user role; based on the declared electricity volume and declared price corresponding to the power generation enterprise role, the power sales company role and the power user role, generating clearing data and clearing curves; and sending the clearing data and the clearing curves to the user.

[0012] In one example, before providing the user with a corresponding type of electricity trading model based on the role identity and trading mode selected by the user, the method also includes: sending simulation prerequisite knowledge and electricity test questions to the user; when the user's test question score is higher than a preset threshold, sending a simulation interface to the user to obtain the role identity and trading mode selected by the user.

[0013] In one example, providing the user with a corresponding type of electricity trading model based on the role identity and transaction mode selected by the user specifically includes: simultaneously acquiring the role identities of multiple users under the same transaction mode; providing the multiple users with corresponding types of electricity trading models based on the role identities of the multiple users; acquiring initial data corresponding to the role identities of the multiple users in a preset database; and sending the initial data to the multiple users so that the multiple users can conduct electricity transactions based on the initial data.

[0014] In one example, the transaction mode type of the electricity transaction model includes at least one of medium- and long-term transactions, spot transactions, day-ahead transactions, and pre-time transactions.

[0015] The present application also provides an electric power trading simulation device based on electric power system operation constraints, comprising: at least one processor; and a memory communicatively connected to the at least one processor; wherein the memory stores instructions executable by the at least one processor, and the instructions are executed by the at least one processor so that the at least one processor can execute: based on the role identity and trading mode selected by the user, providing the user with a corresponding type of electric power trading model; the role identity includes at least one of an electric power trading center, a power generation enterprise, a power sales company and an electric power user; by monitoring the electric power trading operations of the user, obtaining the trading data of the user in the current trading stage; determining the operating constraints of the electric power trading model, the operating constraints include system constraints, unit constraints and network constraints; based on the trading data, the operating constraints and the bidding algorithm, simulating the trading operations of other roles in the electric power trading model in the current trading stage to obtain trading results; returning the trading results to the user so that the user can interact with the electric power trading model based on the trading results.

[0021] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0022] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0023] Figure 1 A flowchart of a method for simulating power trading based on power system operation constraints provided in one or more embodiments of this specification. The process can be executed by a computing device in the corresponding field (e.g., a risk control server or smart mobile terminal corresponding to a payment service), and some input parameters or intermediate results in the process allow manual intervention and adjustment to help improve accuracy.

[0024] The analysis method involved in the embodiments of the present application can be implemented by a terminal device or a server, and the present application does not impose any special restrictions on this. For the convenience of understanding and description, the following embodiments are described in detail by taking a server as an example.

[0025] It should be noted that the server can be a single device or a system composed of multiple devices, that is, a distributed server, and this application does not make any specific limitations on this.

[0026] like Figure 1 As shown, the embodiment of the present application provides a power transaction simulation method based on power system operation constraints, including:

[0027] S101: Based on the role identity and transaction mode selected by the user, provide the user with a corresponding type of electricity transaction model.

[0028] First, the user will select the role identity to be played or simulated from a variety of role identities, and select the corresponding transaction mode. After the selection, the role identity and transaction mode will be sent to the server. The server will select the corresponding power transaction model from the pre-stored power transaction models based on the user's selection and send it to the user, so that the user can simulate power transactions based on the power transaction model.

[0029] It should be noted that the roles here include power trading centers, power generation companies, power sales companies, and power users. Trading modes include medium- and long-term trading, spot trading, day-ahead trading, pre-hour trading, and real-time trading. Among them, medium- and long-term trading mainly refers to power trading for more than a day, such as multi-year, annual, quarterly, monthly, and weekly, carried out by market trading entities such as power generation companies, power sales companies, power users, and independent ancillary service providers that meet the access conditions through market-oriented methods such as autonomous negotiation and centralized bidding. Medium- and long-term trading varieties include direct power trading, inter-provincial and inter-regional trading, contracted power transfer trading, and ancillary service compensation (trading) mechanism. Spot trading refers to power trading conducted one day in advance of real-time operation, that is, within 24 hours. Spot trading generally determines the quantity and price of power trading through bidding. Spot trading includes day-ahead trading, pre-hour trading, and real-time trading. The main purpose of power spot trading is to balance the deviation between contract trading and actual load, and to improve the competitive efficiency of the power market. Day-ahead trading refers to the 24-hour electricity trading of the next day that is conducted one day ahead of the real-time operation (in order to distinguish it from the spot trading that specifically refers to day-ahead trading, it is generally also called day-ahead spot trading). Day-ahead trading is also called hour-ahead trading, daytime trading or adjustment trading, which refers to the electricity trading conducted in a certain period after day-ahead trading and before real-time trading. Real-time trading refers to the electricity trading conducted 1 hour ahead of the real-time operation. Generally speaking, the main purpose of real-time trading is to ensure the real-time balance of power supply and demand.

[0030] In one embodiment, the power trading model here takes power trading and power system as modeling objects, and uses Maya modeling technology to establish regional power systems and power plants, substations, power trading centers and related main equipment three-dimensional animation scenes and equipment operation according to the actual structure and real data of the target area power system. The power trading model includes the power equipment information corresponding to the target area, and the power equipment information here includes transmission lines, substations, generators, loads and other equipment. At the same time, the power trading model adopts B / S architecture, webGL technology, unity3D engine, and a browser-based framework, including front-end, back-end, and database. Through the B / S architecture, users can access the management platform, view related functions, and start the platform and power trading model.

[0031] S102: Acquire the transaction data of the user in the current transaction phase by monitoring the user's power transaction operation.

[0032] After the power trading model is sent to the user, the user will perform power trading operations in the power trading model. At this time, the power trading model can record the user's power trading operations and send the transaction data in the current trading stage to the server. It should be noted that the transaction created by the power trading center includes the transaction start time and end time. The current trading stage here refers to the entire time within the currently created transaction, that is, from the start time of the current transaction to the end time of the current transaction.

[0033] In one embodiment, before obtaining the transaction data provided by the user, in order to make the simulation process closer to the actual situation, the user needs to know the power generation costs of the power generation enterprise and the power sales company that he simulates, so that the user can provide a more realistic declared price. Therefore, before obtaining the user's transaction data, if it is determined that the role identity selected by the user is a power generation enterprise or a power sales company, the power generation cost corresponding to the role identity is sent to the user, so that the user can perform power trading operations based on the power generation cost.

[0034] At the same time, in order to prevent malicious bidding by users in multiplayer mode, after obtaining the transaction data provided by the user, the user's declared price, which has a large gap with other users, especially a price that is too low, can be determined based on the historical clearing price and the quotations of different users this time, to prevent malicious bidding. Therefore, after obtaining the user's transaction data, if it is determined that there are other users whose role identities are power generation enterprises or power sales companies, the historical clearing prices of all users in the simulation process are obtained, and the historical clearing prices are processed, such as interpolation processing, removing the maximum or minimum value, etc., so as to obtain the historical clearing price range of the price comparison journey. Then, according to the current declared prices of all users obtained, and based on the current declared prices, the average declared price of the current transaction is determined. Then, based on the average declared price and the historical clearing price range, the malicious bidding users among other users can be determined. Specifically, the maximum value of the absolute value of the difference between the two endpoints of the historical clearing price range and the average declared price can be used as the floating price threshold, and then the difference between the average declared price and the current declared price can be used as the actual floating value; if the actual floating value is greater than the product of the preset threshold and the floating price threshold, the corresponding user is regarded as a malicious bidding user. After the malicious bidding user is identified, the declared price corresponding to the malicious bidding user needs to be cleared from the transaction data to prevent the simulation process of other users from being affected by the user.

[0035] S103: Determine operating constraints of the power trading model.

[0036] In real life, power trading needs to consider operating constraints, so it is necessary to incorporate system constraints, unit constraints and network constraints into the modeling process to ensure the feasibility of the trading plan and the stable operation of the market. When formulating a power bidding trading plan, the following constraints must be considered: System constraints: including system total load balance constraints, system static reserve constraints and system spinning reserve constraints. These constraints ensure the stable operation of the power system and the reliability of power supply. Unit constraints: including unit output range constraints, unit output change speed constraints, unit minimum start and stop time constraints, etc. These constraints limit the operating range and flexibility of the unit and ensure the safe and economic operation of the unit. Network constraints: including intra-regional line transmission capacity constraints and inter-regional tie line transmission capacity constraints. These constraints limit the transmission capacity of electricity in the power grid and ensure the stable operation of the power grid and the reliability of power transmission. Once the transaction triggers the output limit of the equipment, the overload animation or overload plot is triggered, which can make the user aware of the possible consequences of the current operation.

[0037] S104: Based on the transaction data, the operating constraints and the bidding algorithm, simulate the transaction operations of other roles in the power transaction model in the current transaction stage to obtain transaction results.

[0038] After the server obtains the user's transaction data, it can simulate the transaction operations of other roles in the power trading model in the current transaction stage based on the user's transaction data and the fictitious data of other roles pre-stored in the database, as well as the running constraints and bidding algorithm to obtain the transaction results.

[0039] It should be noted that the fictitious data of the above-mentioned other roles can be pre-stored in the storage device of the computer device. When the transaction operation needs to be simulated, the computer device can select the fictitious data of other roles from the storage device. Of course, the computer device can also obtain the fictitious data of the other roles from other external devices. For example, the fictitious data of other roles are stored in the cloud. When the transaction operation needs to be simulated, the computer device can obtain the fictitious data of other roles from the cloud. This embodiment does not limit the way to obtain the fictitious data of other roles. The power trading model is based on the bidding algorithm, SCUC (safety constrained unit combination) and SCED (safety constrained economic dispatch) algorithm. The bidding algorithm realizes the supply and demand balance and price discovery of the power market through the price mechanism; SCUC (safety constrained unit combination) and SCED (safety constrained economic dispatch) algorithms realize the safe and stable operation and economic dispatch of the power system through the optimization model. Simulate the bidding, dispatching and optimization process of the power market, so that users can have a deep understanding of the operation mechanism of the power market.

[0040] In one embodiment, if the role selected by the user is a trading center role, during the simulation process, the server will create a transaction based on the transaction-related information sent by the user, where the transaction-related information includes the transaction number, transaction name, transaction type, transaction start time, and transaction end time. After the user creates a transaction, the user can start the transaction in the power trading model. At this time, the server will obtain the fictitious data corresponding to other roles in the preset database at the current trading stage, where the fictitious data includes the declared power and the declared price. After the server obtains the declared power and the declared price of all roles, it will clear the declared intentions of all roles according to the bidding algorithm, thereby determining the winning role. If it is a multiplayer mode at this time, it is also necessary to conduct a safety check on the declared power declared by the role played by the user (such as the role of a power generation enterprise), that is, whether the power generation exceeds the output range of the generator set. If it exceeds the output range, the consequences that may be caused will be displayed in the power trading model of the corresponding user. After the safety check is passed, the transaction ends. In the safety check stage of the transaction process, the 3D model of the main equipment of the system, boilers, generators, transformers, power line operation status changes, faults and accident scenes is highly simulated, presenting the consequences of trading behaviors that do not conform to the system operation rules.

[0041] In one embodiment, if the user is a power generation enterprise role, a power sales company role or a power user role, in the process of simulating power trading, the declared quantity and declared price sent by the user must first be security checked based on the operating constraints; after the check is passed, the server obtains the declared electricity quantity and declared price of other roles in the preset database; and based on the bidding algorithm, the declared electricity quantity and declared price of other roles are traded and cleared to obtain the winning bid information of all roles; and the winning bid information of all roles is sent to the user.

[0042] Specifically, when determining the winning bid information, it is necessary to determine the seller role and buyer role corresponding to the current exchange based on the transaction information provided by all roles, obtain the seller role's power supply, the seller's power pricing, and the buyer role's power demand, and determine the length of the power transportation line between the seller role and the buyer role and the power loss coefficient. The loss value of electricity during transportation can be determined by the length of the power transportation line and the power loss coefficient corresponding to the line; then the winning seller corresponding to the target transaction can be determined based on factors such as the seller's power supply, power pricing, and the seller's corporate level. The corporate level here can be a corporate portrait that reflects transaction risks, such as the company's credit rating and the company's volume level.

[0043] Specifically, the expected value of the transaction plan corresponding to different sellers can be determined by the following formula:

[0044]

[0045] Among them, I is the expected value of the transaction plan, S is the length of the power transmission line, p is the power loss coefficient of the power transmission line, Q is the seller's power supply, R is the seller's enterprise level, G is the seller's power pricing, and B is a preset constant.

[0046] S105: Returning the transaction result to the user, so that the user can interact with the electricity transaction model based on the transaction result.

[0047] After the power trading model obtains the transaction results, the server will return the transaction results to the user. On the one hand, the user can check whether his or her transaction operation has won the bid, and check the bid and declaration data of the winning role. On the other hand, the user can conduct subsequent simulated transactions based on the transaction results.

[0048] In one embodiment, in order to facilitate users to view the transaction results, the transaction results can be visualized. In the process of returning the transaction results to the user, the server can determine the winning power generation enterprise role, power sales company role and power user role based on the transaction results, and obtain the declared electricity and declared prices corresponding to the power generation enterprise role, power sales company role and power user role respectively. Then, based on the declared electricity and declared prices corresponding to the power generation enterprise role, power sales company role and power user role, the clearing data and clearing curve are prepared; and the clearing data and the clearing curve are sent to the user.

[0049] In one embodiment, in order to facilitate users to learn relevant knowledge about power trading and improve the efficiency of power trading simulation, simulation pre-knowledge and power test questions can be sent to users before users use the power trading model, so as to obtain the user's first test score corresponding to the power test questions; and when the user's test question score is higher than the preset threshold, it means that the user has a good grasp of the simulation pre-knowledge. At this time, the simulation interface is sent to the user to obtain the role identity and trading mode selected by the user. If the user's first test score is lower than the preset threshold, a teaching video can be provided to the user, and real-time prompts can be provided to the user in the subsequent power simulation transaction process to increase the user's grasp of the simulation pre-knowledge and assist the user in power trading simulation.

[0050] In addition, during the user's simulated power trading process, the user's simulated operations can be collected, and the user's second test score can be determined based on the simulated operations. When determining the second test score, the second test score can be determined based on the operation time of the user performing various operations. If the user's second test score is lower than the preset threshold, a teaching video is provided to the user to help the user master the power trading simulation process. Users with the same characteristics can also be fitted into a user group corresponding to the same characteristics, for example, all students in a class, all students in a school, all personnel in a company, etc., and the score values ​​corresponding to the user group at each test point are obtained, and the score values ​​corresponding to the user group at each test point are plotted as a score curve, and the score curve is sent to the teaching staff, so that the teaching staff can collectively educate the user group through the score curve.

[0051] In one embodiment, when conducting a power transaction simulation, multiple users can conduct a power transaction simulation at the same time. At this time, multiple users play different types of user roles, and explore and present the complete process of role selection, transaction management, bidding and quotation, transaction summary, and transaction settlement and clearing in power transactions under the two transaction modes of medium- and long-term transactions and spot transactions through a multiplayer game mode. When using the multiplayer mode, when providing power transaction models to different users, it is necessary to obtain the role identities of multiple users at the same time under the same transaction mode; based on the role identities of multiple users, provide corresponding types of power transaction models to multiple users respectively; obtain the initial data corresponding to the role identities of multiple users in the preset database; send the initial data to the multiple users so that the multiple users can conduct power transactions according to the initial data.

[0052] like Figure 2 As shown, the embodiment of the present application also provides a power trading simulation device based on power system operation constraints, including:

[0053] at least one processor; and,

[0054] a memory communicatively connected to the at least one processor; wherein,

[0055] The memory stores instructions executable by the at least one processor, the instructions being executed by the at least one processor to enable the at least one processor to:

[0057] The embodiment of the present application further provides a non-volatile computer storage medium storing computer executable instructions, wherein the computer executable instructions are configured as follows:

[0058] Based on the role identity and transaction mode selected by the user, a corresponding type of power transaction model is provided to the user; the role identity includes at least one of a power transaction center, a power generation enterprise, a power sales company and a power user; by monitoring the power transaction operation of the user, the transaction data of the user in the current transaction stage is obtained; the operation constraints of the power transaction model are determined, and the operation constraints include system constraints, unit constraints and network constraints; based on the transaction data, the operation constraints and the bidding algorithm, the transaction operations of other roles in the power transaction model in the current transaction stage are simulated to obtain transaction results; the transaction results are returned to the user so that the user can interact with the power transaction model based on the transaction results.
