Description

Technical Field

[0001] The present invention relates to technical fields such as new power systems and smart grids, and particularly relates to a method and system for information interaction in power grid operation management. Background Art

[0002] The power grid dispatching agency and dispatching objects (power plants, users, etc.) achieve grid-source coordination by exchanging data such as equipment maintenance information, generation plans, and power outage information, which is a key link to ensure the safe operation and reliable power supply of the power grid. In the existing technical solutions, the power grid dispatching management information system (OMS, Operation Management System, see patent CN110866708B "A power grid dispatching management system and its application method") is used as the core interaction platform, and the remote terminal login method is adopted to realize the information interaction between the dispatching object and the OMS: the dispatching object manually completes operations such as declaring maintenance plans and receiving dispatching instructions through the terminal interface, and the data involved needs to be manually exported from its own digital system to the OMS, while the received dispatching information also needs to be manually entered into the own system again.

[0003] With the increasing proportion of new energy, the power grid shows two significant technological evolutions: Resource form transformation: Distributed resources such as distributed photovoltaics are highly penetrated, forming a distributed resource aggregation control form represented by virtual power plants; Expansion of architecture levels: The system architecture evolves from the traditional "power grid dispatching - power plant" mode to a three-level system of "power grid dispatching - centralized control center - power plant (distributed resources)".

[0004] Under this background, the traditional OMS interaction mode exposes the following technical defects: a) Low interaction efficiency: The manual operation process (data export, terminal login, information entry) leads to an overly long operation chain and poor user experience; b) Insufficient real-time performance: The dynamic response requirement of distributed resources reaches the second level, but there is a minute-level delay in manual interaction, which cannot meet the real-time dispatching requirements of the new power grid; c) Risk of data inaccuracy: Manual transfer is prone to introduce data misalignment, format deviation, and abnormal values, affecting the reliability of dispatching decisions. Summary of the Invention

[0005] The present invention provides a method and system for operation management information interaction, aiming to solve the problems of low interaction efficiency, poor real-time performance, and insufficient accuracy caused by heterogeneity and manual operation between the existing power grid dispatching management system (OMS) and the dispatching object's own digital system, and overcome the technical barriers of information security and protocol compatibility faced by cross-system interconnection.

[0006] The method includes: establishing a mapping relationship between the physical system and the virtual service module in the interaction device, and realizing the automatic routing and secure transmission of data between heterogeneous systems by encapsulating the original service data into a standardized information object containing a classification identification field and a data payload field. Through the above technical solution, the efficiency of scheduling information interaction can be significantly improved, the dynamic service expansion under the multi-level architecture of the new power system can be supported, and the integrity and real-time performance of data transmission can be guaranteed.

[0007] The above-mentioned heterogeneous systems are systems with different technical standards or communication protocols.

[0008] In a specific implementation of the present invention, the heterogeneous systems include the grid dispatching operation management system (DOMS) and the dispatching object operation management system (AOMS).

[0009] Furthermore, the classification identification field is the Info_Operation field, which is used to store the virtual service module name; the data payload field is the Info_body field, which is used to store the original service data payload. By defining a standardized field structure, the unified design of the interaction interface is realized, the differences of the underlying systems are shielded, and at the same time, the flexible expansion ability of the service data is retained.

[0010] Furthermore, the standardized information object also includes the following fields: Info_objectType field: Identifies the object type of the service data, which is used for the receiving end to achieve fast classification processing without parsing the data payload; Info_objectID field: Identifies the object instance of the service data, which supports precise data distribution for specific devices or sites; Info_format field: Declares the format of the data payload field, which is customized by the end system and does not need to be parsed by the interaction device, so as to support the plug-and-play of new service formats.

[0011] Furthermore, the mapping relationship is stored in the form of a mapping table, which includes the service module name, the physical system identifier, and the routing path field. Through the structured mapping table design, the system maintenance complexity is reduced, and the dynamic addition and deletion of the physical system and the online update of the service module are supported.

[0012] Furthermore, the interaction device performs end-to-end encryption, generates a transmission message containing a message sequence number and a time stamp, and ensures data integrity through the receiving end verification mechanism. Specifically, it includes: End-to-end encryption: Adopts the mechanism of encryption at the sending end and decryption at the receiving end to prevent the leakage of sensitive information in the transmission link; Message sequence number and time stamp: Detects data loss or duplication through a globally unique incrementing sequence number, and realizes real-time transmission monitoring by combining the time stamp delay threshold determination; Digital signature verification: Verify the legitimacy of the data source and the integrity of the content, preventing data tampering and repudiation.

[0013] Furthermore, the time stamp delay threshold is a fixed value predefined by the receiving end. For example, it is set to 5 seconds. Exceeding this threshold triggers an alarm and marks the delay status, providing a clear basis for anomaly handling for operation and maintenance personnel.

[0014] To implement the above method, the present invention also provides an operation management information interaction system, including: Mapping module: Maintain the mapping relationship between the physical system and the virtual service module, supporting dynamic configuration and multi-version compatibility; Encapsulation module: Encapsulate the original service data into a standard information object, retaining the original format and semantics of the service data; Transmission control module: Implement intelligent routing based on the classification identification field, and integrate functions such as encryption, sequence number generation, and protocol conversion; Verification module: Ensure the credibility and reliability of the interaction process by parsing the continuity of the sequence number, the time stamp delay threshold, and the validity of the digital signature.

[0015] Furthermore, the encapsulation module does not parse the data payload field (Info_body), but only transparently transmits it according to the format declared by the Info_format field. This design enables the interaction device to not need to understand the specific content of the service data, reducing both the system processing burden and the security risks caused by parsing sensitive data.

[0016] Furthermore, the transmission control module establishes a VPN channel through a firewall or an Internet security isolation device to meet the security protection regulations of the power monitoring system (such as "security zoning, network specialization, horizontal isolation, and vertical authentication"), ensuring the compliance and security of cross-system interaction.

[0017] Furthermore, the interaction device is a general server or an embedded system, and the hardware form can be flexibly selected according to the deployment scenario. For example, a high-availability server cluster is adopted on the dispatching master station side, and a low-power embedded device is adopted on the distributed resource side to achieve optimized resource configuration and cost control.

[0018] And, an electronic device, including a memory, a processor, and a computer program stored on the memory and executable on the processor, characterized in that when the processor executes the program, it implements the steps of the power grid operation management information interaction method as described above.

[0019] A non-transitory computer-readable storage medium, on which a computer program is stored, characterized in that when the computer program is executed by a processor, it implements the steps of the power grid operation management information interaction method as described above.

[0020] Compared with the prior art, the present invention and its preferred solutions have at least the following beneficial effects: Efficiency improvement: Eliminate manual data transfer operations and significantly shorten the interactive response time; Dynamic expansion ability: Through the design of standardized information objects and mapping tables, support the online access of new business modules without modifying the core code of the interactive device; Enhanced security: End-to-end encryption and digital signature mechanisms effectively resist the risks of data leakage and tampering; Compatibility guarantee: The virtualization mapping mechanism is compatible with OMS and scheduling object systems with different technical standards.

[0021] Based on the solution architecture provided by the present invention, it can also be applied to the information interaction between two systems in other industries. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] In the following, specific embodiments of the present application will be described in detail with reference to the drawings. According to these detailed descriptions, those skilled in the art can clearly understand the present application and can implement the present application. Without departing from the principle of the present application, the features in different embodiments can be combined to obtain new embodiments, or some features in certain embodiments can be replaced to obtain other preferred embodiments.

[0024] Given that the interconnection and interoperability of digital systems have currently become a commonly adopted technical means, they have not been adopted in the power grid dispatching operation management system and the digital system of the dispatching object itself for a long time. The main reasons are as follows: Information security issues: The power grid operation management system involves a large amount of sensitive information and key data. The interconnection and interoperability of the system may bring information security risks, such as data leakage, malicious attacks, etc.

[0025] There is no effective solution: The data and services are complex, and different systems and devices may adopt different technical standards and protocols, resulting in difficulty in achieving seamless connection and data sharing between systems.

[0026] The interactive system and method proposed in the embodiment of the present invention abstract complex business data to achieve simple, efficient and secure interaction.

[0027] 1. System Composition and Information Interaction Requirements The overall system composition is as Figure 1 shown Figure 1 In the figure, the power grid operation management system of the power grid dispatching agency (abbreviated as DOMS) and the operation management system of the dispatching object (abbreviated as AOMS) are the application ends of the information interaction system, and there can be one or more DOMS and AOMS. Among them, the security device is configured according to the security protection intensity of DOMS according to the network adopted, and generally uses a firewall or an Internet security isolation device. The security device and the wide area network provide a secure network channel (VPN) for the interaction device. The information interaction device involved in the present invention can be a general server or an embedded system, and provides transparent data interaction services for DOMS and AOMS.

[0028] For the end systems DOMS and AOMS of information interaction, each party has diversified and complex services. Generally, the end system contains a set of integrated systems or multiple business-oriented information subsystems. The number of subsystems included in each end system and the services of each subsystem may be inconsistent, and the interaction device needs to be able to adapt to this complex situation.

[0029] For DOMS and AOMS, the content of information interaction is also extremely complex. Generally, dispatching management includes: power grid, relay protection, dispatching automation, dispatching control of communication systems, equipment maintenance, dispatching plans, market-based operations, etc., covering the operation management of the entire life cycle of the power grid and power generation system from construction, operation to retirement. Moreover, with the continuous deepening of power grid digitization, the content of information interaction will continue to increase and change. The interaction system must adapt to this situation, not only support complex services, but also be able to flexibly expand the interaction content without modifying the interaction system.

[0030] 2. Implementation Scheme According to the interaction requirements, the system must first solve the following difficulties and problems: a) The interaction device needs to be able to adapt to the problem that the number of subsystems included in each end system and the services of each subsystem may be inconsistent; b) It can not only support complex services, but also be able to flexibly expand the interaction content without modifying the interaction system; c) Solve the information security problem, and must achieve end-to-end security of the application. There should be no information leakage problem in the interaction system; d) Solve the reliability problem, and must ensure that the information can be reliably delivered and is unique.

[0031] Among them: a) and b) are unique problems of DOMS and AOMS information interaction.

[0032] (1) Solution to Problem a) Regarding the inconsistency problem between the end - system DOMS and AOMS for information interaction, the solution provided by the embodiments of the present invention is based on services. The end - system is abstracted into an integrated virtual management system composed of a series of service (Operation) modules. A mapping relationship table from the physical system to the virtual system is established at both ends of the interaction. Different physical systems are mapped to unified service modules, and interactions are carried out in the form of modules as Figure 2 shown.

[0033] Among them, the mapping table includes a list of information such as the service module name and the physical system where the service module is located. When the information interaction device receives the corresponding service information, it routes it to the corresponding system according to the mapping table information.

[0034] This solution realizes the unified alignment of DOMS and AOMS built by different methods by maintaining different mapping relationships in the information interaction device.

[0035] (2)Solution to problem b) Since there is a large amount of interaction content between DOMS and AOMS, and the formats are different. To support complex services and achieve the expansion of interaction content without modifying the interaction system, a general information - bearing method is needed.

[0036] In DOMS and AOMS, it is difficult to express the information of all types of services in a unified format. Forcing the use of a unified format will cause additional processing burdens. This system adopts the method of having the service modules agree on the information format by themselves, and the information interaction system encapsulates the data to be transmitted into abstract information objects to achieve this.

[0037] According to the characteristics of the services, the present invention uniformly abstracts the power grid dispatching information into a data object composed of "OMS service name" + "object type" + "object name" + "information body format" + "information body", as shown in Table 1: Table 1 Attributes of OMS Information Object (OMS_Info)

[0038] Service information Info_Operation: It is the OMS service name, which is equivalent to the service module name in the mapping table in Table 1. The interaction device routes the information object to the corresponding physical system through this information; Information body Info_body: It is the actual payload of the interaction, which is only understood and interpreted by the corresponding software module of the physical system according to the agreement. The interaction device regards it as an unknown data block and keeps it confidential; Information attributes Info_objectType, Info_objectID, Info_format: These are optional. It is agreed by the physical system and business modules whether to use them and how to use them. Information attributes are the information of the information body exposed during the interaction process, providing support for fast processing without parsing the information body status, such as secondary distribution, filtering, parsing, etc. of the system.

[0039] Info_objectType: Typically used to identify different data objects in the same business; Info_objectID: Typically used to identify different management objects, such as a specific substation, equipment, etc.; Info_format: Typically used to identify the data format of the Info_body, and the end system identifies and parses the data. Such as: identifying whether the data is encrypted, the data format, etc.; This solution adopts the method of the business module agreeing on the information format by itself, making the interaction system independent of the interaction information. Therefore, it can adapt to the diverse requirements of different businesses for information formats, support fast processing in the state where the transmission system does not parse the information body, and achieve the maximum degree of confidentiality.

[0040] (3) Solutions to problems c) and d) For the security and confidentiality requirements of information interaction, the design of the interaction system adopts an end-to-end security solution: encrypting by the sending-end application end system and decrypting by the receiving-end application end system, without parsing the data during the intermediate transmission process.

[0041] To achieve the uniqueness, accuracy, and security of information transmission, the interaction system adopts the following measures: The sending end numbers the interaction information: forming a unique sequence number for each interaction to achieve the unique management of information; the receiving end judges message repetition: parses the sequence number, determines whether the sequence number already exists, and if it exists, returns the message repetition status and discards the information; Message loss determination: determines whether the sequence number is the previous number +1. If not, returns the message may be lost status, sets the received number as the current sequence number and continues the subsequent processing. If it is, returns the receive correct status; Real-time determination: The sending end stamps the interaction information with a time mark: records the time of each interaction (the time when the interaction request is received) to track the delay situation of the information; the receiving end extracts the received time and compares it with the current time (subtracts the current time). If it is greater than a certain preset value, it marks that the received information has a too large delay and sends a reminder message, and performs subsequent processing according to the policy; Encrypt the information: According to the data confidentiality requirements, encrypt the information object (OMS_Info) data (optional) (used in occasions with high confidentiality requirements and no self - confidentiality function). The sender performs a digital signature on the data, and the receiver verifies the signature. If the signature verification fails, an error status is returned, and the information is discarded. If the verification passes, subsequent processing is carried out. The signature content includes: signing the interaction information body, number, and time stamp, which solves problems such as the correctness, integrity, identity authentication, and non - repudiation of the information. (4)Information interaction interface primitives For the implementation solution, the system designed a grammar for realizing information interaction between DOMS and AOMS using a single statement. The grammar is as follows: OMS_Msg( / / Operation and management message IN String:sender, / / Sender name IN String:receiver, / / Receiver name IN Number:sequence, / / Message sequence number IN String:time, / / Received time IN String:signature, / / Digital signature IN OMS_Info:info, / / OMS information object OUT String:status) / / Return status The meanings of each attribute are as follows: Sender: The address of the sender information interaction device Receiver: The address of the receiver information interaction device Sequence: Information sequence number, used for information uniqueness control; Time: Time stamp, used for real - time determination Signature: Digital signature Info: Information body OMS_Info, carrying service data This interface primitive can also be used for the end - system to submit tasks to the information interaction system and for information interaction between subsystems within the end - system.

[0042] (5)Information interaction process The interface between DOMS and AOMS uses a push - based unidirectional transmission method. When requesting information from the other party, the content to be requested is pushed to the other party, and the receiver pushes the corresponding information to the requester according to the request content.

[0043] The information interaction process is as Figure 3As shown in: Step 1: Abstractly encapsulate the information Since the application side between DOMS and AOMS delivers the information to the information interaction system after encapsulating according to the format of: "OMS service name" + "object type" + "object name" + "information body format" + "information body".

[0044] Step 2: Identify, encrypt, sign, and transmit the information This step is completed by the sending-end interaction device and includes the following links: Number the interaction information: Form a unique sequence number for each interaction to achieve the unique management of the information; Timestamp the interaction information: Record the time of each interaction (the time when the interaction request is received) to track the delay situation of the information; Encrypt the information: Encrypt the information object (OMS_Info) data according to the data confidentiality requirements (optional); Digitally sign the data: Sign the interaction information, number, and timestamp to ensure the correctness and credibility of the information; Send the information to the receiving end through the underlying protocol: Send the sender, receiver, number, timestamp, digital signature, and information object (OMS_Info) to the receiving end according to the underlying protocol determined by the implementation environment. For example, call the following general service protocol interface of the power system: OMS_Msg ( / / Operation management message IN String: sender, / / Name of the sending end IN String: receiver, / / Name of the receiving end IN Number: sequence, / / Message sequence number IN String: time, / / Received time IN String: signature, / / Digital signature IN OMS_Info: info, / / OMS information object OUT String: status) / / Return status Step 3: Verify and route the information This step is completed by the receiving-end interaction device and includes the following links: Verify the signature. If the signature verification fails, return an error status and discard the information. If the verification passes, proceed with the subsequent processing; Message duplication determination: Analyze the sequence number and determine whether the sequence number already exists. If it exists, return the message duplication status and discard the information; Message loss determination: Determine whether the serial number is the previous number + 1. If not, return the message may be lost status, set the received number as the current sequence number, and continue with subsequent processing. If it is, return the received correctly status; Real-time determination: Extract the received time, compare it with the current time (subtract the current time). If it is greater than a certain preset value, mark that the received information has a too large delay, send a reminder message, and perform subsequent processing according to the policy; Data decryption; Decrypt the information object (OMS_Info) Send the data to the receiver: Send it to the corresponding application end according to the Info_Operation in the decrypted information object (OMS_Info); Step 4: The receiving end performs application processing Receiving end data parsing: The receiving end parses the Info_body according to Info_Operation (OMS service name), Info_objectType (object type), Info_objectID (object name), and Info_format (information body format); Receiving end application processing: Perform corresponding processing according to the application's agreement.

[0045] Thus, the core innovation of the embodiments of the present invention is to achieve efficient cross-system interaction through the collaborative design of the following technical features: Business virtualization mapping mechanism: By establishing a mapping table between the physical system and the virtual business module, heterogeneous subsystems of DOMS / AOMS (such as "maintenance plan management", "power generation scheduling", etc.) are abstracted into standardized business modules, shielding the underlying system differences.

[0046] Dynamic encapsulation of OMS_Info object: Use the structure of "Info_Operation (service name) + Info_body (data payload)" to encapsulate data, allow the end system to customize the data format through the Info_format field (such as JSON, XML), and the interaction device only transparently transmits the data payload without parsing or modifying.

[0047] Built-in security transmission mechanism: Uniqueness control: Detect data loss or duplication through a globally incrementing serial number; Real-time monitoring: Determine the transmission delay based on the time stamp at the sending end and the receiving end delay threshold; End-to-end security: Use digital signatures to verify the data source and integrity, and combine optional encryption to ensure privacy.
