Description

Technical Field

[0001] The present application relates to the technical field of power systems, and in particular to a method and device for splitting a power business system. Background Art

[0002] With the development of the power Internet of Things, the new power system presents multi-source heterogeneous bottlenecks and a surge in power grid data. The increasing demand for diversified and ecological power business applications derived from data value has posed severe challenges to the existing power terminal information system.

[0003] After the traditional power terminal information system is put into use, it is usually continuously maintained and upgraded as the business needs change. A large part of the reason for the change in demand after the system is put into use comes from the continuous access and transformation of new energy services and the increase in user needs. In order to adapt to the application changes caused by changes in scenarios, the business can be decomposed in the business design stage of terminal processing. However, the business organizational structure of the traditional power terminal information system generally adopts a monolithic architecture. Once the business scale expands, due to the complexity of business functions and the tight coupling between businesses, after changing business needs, it is necessary to modify most of the business parts while modifying a few business functions, and it is impossible to accurately provide organizational structure expansion for a specific business service. Therefore, there are limitations in business expansion and change. Summary of the invention

[0056] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0057] The power business system splitting method provided in the embodiment of the present application can be applied to the application environment shown in Figure 1. Among them, the terminal 102 communicates with the server 104 through the network. The data storage system can store the data that the server 104 needs to process. The data storage system can be integrated on the server 104, or it can be placed on the cloud or other network servers. This embodiment uses the method applied to the terminal 102 as an example. It can be understood that the method can also be applied to the server, and can also be applied to the system including the terminal and the server, and is implemented through the interaction between the terminal and the server. The terminal 102 obtains multiple business function characteristics and multiple splitting strategies of the power business system; for each splitting strategy, based on the current splitting strategy and multiple business function characteristics, multiple functional components corresponding to the power business system under the current splitting strategy are determined; the component type corresponding to each functional component is determined, and based on the number of occurrences of multiple functional components and multiple component types in the use cases of the power business system under the current splitting strategy, the splitting constraint index corresponding to the current splitting strategy is determined; based on the number of internal interactions and external interactions corresponding to each of the multiple functional components under the current splitting strategy, the splitting evaluation index corresponding to the current splitting strategy is determined; based on the splitting constraint index and splitting evaluation index corresponding to each of the multiple splitting strategies, a target splitting strategy is determined in the multiple splitting strategies, and the target splitting strategy is used to split the power business system. Among them, the terminal 102 can be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, Internet of Things devices and portable wearable devices, and the Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, smart car devices, projection devices, etc. Portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. The head mounted device may be a virtual reality (VR) device, an augmented reality (AR) device, smart glasses, etc. The server 104 may be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud computing services.

[0058] In an exemplary embodiment, as shown in FIG2 , a method for splitting a power business system is provided, which is described by taking the method applied to the terminal 102 in FIG1 as an example, and includes the following steps 202 to 206. Among them:

[0059] Step 202: Acquire various business function characteristics and various splitting strategies of the electric power business system.

[0060] The power business system refers to the power terminal system used to process power business. The business function characteristics refer to the business function types provided by the power business system. For example, the business function characteristics include protection type, demand response type, power quality type, etc. The split strategy refers to the pre-set strategy for splitting the power business system.

[0061] Step 204, for each splitting strategy, based on the current splitting strategy and multiple business function characteristics, determine multiple functional components corresponding to the power business system under the current splitting strategy; determine the component type corresponding to each functional component, and based on the number of occurrences of each of the multiple functional components and the multiple component types in the use cases of the power business system under the current splitting strategy, determine the splitting constraint index corresponding to the current splitting strategy; based on the number of internal interactions and external interactions corresponding to each of the multiple functional components under the current splitting strategy, determine the splitting evaluation index corresponding to the current splitting strategy.

[0062] Among them, the use of multiple splitting strategies can split the power business system into multiple different functional component combinations. Under each functional component combination, the coupling between the functional components is different. Therefore, for each splitting strategy, the corresponding splitting constraint indicators and splitting evaluation indicators are determined respectively, so as to constrain and evaluate the multiple splitting strategies.

[0063] Functional components refer to functional components under the microservice architecture. The microservice architecture is used to split the power business system. The power business system has a simple organizational structure, which is conducive to reducing the frequency of information exchange between multiple functional components and reducing the degree of coupling. In some embodiments, the current splitting strategy indicates that each business functional characteristic can correspond to one functional component, and can also indicate that multiple business functional characteristics correspond to one functional component.

[0064] In other embodiments, the current splitting strategy may indicate that the power business system is split into a single layer according to the business function characteristics to obtain multiple functional components; the current splitting strategy may also indicate that the power business system is split according to the business function characteristics, and then the split results are split to obtain multi-level functional components. As shown in FIG3, a schematic diagram of functional components in an embodiment. After the power business system is split, multiple functional components at the top level are obtained, which are protection type, demand response type, power quality type, energy management type, etc. Then, the multiple functional components at the top level are split respectively to obtain multiple functional components at the second level. Taking the functional components of the power quality type as an example, the functional components of the power quality type can be split into reactive compensation, node parameters, harmonics, power factors, etc. Subsequently, the multiple functional components at the second level are split respectively to obtain multiple functional components at the third level. Taking the harmonic functional components as an example, the harmonic functional components can be split into sampling, Fourier analysis, instruction upshift, instruction downshift, etc.

[0065] In some embodiments, the size of the functional component hierarchy is referred to as hierarchical granularity. FIG4 is a schematic diagram of the hierarchical relationship of functional components in one embodiment. The hierarchical granularity method can be used to characterize the relative size of each functional component and the hierarchical relationship of the business organization process in which it is located.

[0066] The component type refers to the attribute feature type of the functional component. For example, one functional component can correspond to one attribute feature type, and one attribute feature type can correspond to multiple functional components. For example, the component types corresponding to instruction downshift and sampling in the functional component are both control types, and the component types corresponding to Fourier analysis include analysis type and data type.

[0067] In the case where the functional components have multiple levels, the component type may be the attribute feature type corresponding to each of the functional components of the last level.

[0068] Functional components are independent units for constructing the power business system. The overall model of functional components of the power business system can be constructed using the directed acyclic graph method. As shown in Figure 5, it is a schematic diagram of the splitting process of the power business system in one embodiment. The overall model of functional components can be expressed as L=(N,E,K,S), where N={1,2,…,n} represents the set of next-level functional components, n is the number of next-level functional components, K represents the level of the functional component, and S is the component type contained in the functional component. Represents the set of directed edges of dependencies between functional components. , functional component i is the direct predecessor component of functional component j, and functional component j is the direct successor component of functional component i. In addition, each The directed edges and weights of Related, Represents the amount of data transferred from functional component i to functional component j.

[0069] The use case of the power business system refers to the use case of the actual business needs of the power business system, which can be used to describe the actual business demand information. In view of the problem of insufficient analysis of the business information characteristics of the power business system in the overall model of functional components, a problem model is constructed through system and demand analysis, and a relationship diagram containing various functional components and component types is established to characterize the internal connection of the power business system information, quantify the relationship between functional nodes, and assign weights to the edges in the diagram.

[0070] As shown in Figure 6, it is a relationship diagram of functional components and component types in an embodiment. Wherein, P represents the functional component, and DS represents the component type. In some embodiments, a triple G = (A, E, R) is used to represent the relationship diagram, wherein A represents the node set of the component type {a1, a2, a3, ...}; E represents the node set of the functional component {e1, e2, e3, ...}; the correlation between each node is represented by an edge, and R represents a set of edges, which includes two types of edges, namely, the edge R (ai, ej) between the functional component and the component type, and the edge R (ei, ej) between the functional component and the functional component. The relationship diagram of functional components and component types containing two types of nodes can better describe the belonging and parallel relationship between different functional components and component types, and can more comprehensively represent the structural characteristics and information. The expression of the edge between each node is as follows:

[0071]

[0072]

[0073] Each use case may include information about functional components and component types. Therefore, each use case may construct a subgraph of the functional component and component type relationship graph.

[0074] The number of internal interactions refers to the number of interactions between multiple sub-functional components corresponding to the current functional component. The number of external interactions refers to the number of interactions between functional component i and functional component j.

[0075] The split constraint index is used to characterize the degree of information exchange between functional components and component types. The split evaluation index is used to characterize the split effect of the power business system.

[0076] Step 206 , based on the splitting constraint indicators and splitting evaluation indicators corresponding to the multiple splitting strategies, a target splitting strategy is determined from the multiple splitting strategies, and the target splitting strategy is used to split the power business system.

[0077] Among them, the terminal determines the optimal target splitting strategy among multiple splitting strategies according to the splitting constraint indicators and splitting evaluation indicators, and splits the power business system according to the target splitting strategy, which can reduce the coupling between multiple functional components and is conducive to the flexible expansion and change of the power business system, providing research ideas for the modeling of the power business organizational structure of the new power system and the expansion and change of the business.

[0078] In the above-mentioned power business system splitting method, the power business system is divided into multiple functional components through various business function characteristics of the power business system and each splitting strategy. Different division strategies have different division methods for functional components. For each division strategy, the splitting constraint index can be determined based on the number of occurrences of multiple functional components and multiple component types in the use cases of the power business system under the current splitting strategy, and the splitting evaluation index can be determined based on the number of internal interactions and external interactions corresponding to each of the multiple functional components under the current splitting strategy. Since the splitting constraint index and the splitting evaluation index quantify the association between functional components and component types, the optimal target splitting strategy can be determined according to the splitting constraint index and the splitting evaluation index corresponding to each of the multiple splitting strategies. Splitting the power business system based on the target splitting strategy can reduce the coupling between multiple functional components, which is conducive to the flexible expansion and change of the power business system.

[0079] In an exemplary embodiment, based on the current split strategy and multiple business function characteristics, multiple functional components corresponding to the power business system under the current split strategy are determined, including: based on the current split strategy and multiple business function characteristics, the power business system is divided into multiple levels to obtain multi-level functional components, each level of functional components includes multiple functional components, and the functional components of the current level are obtained by dividing the functional components of the previous level; the multi-level functional components are used as multiple functional components corresponding to the power business system under the current split strategy.

[0080] Among them, multi-level division refers to dividing the power business system according to the current splitting strategy to obtain multiple functional components at the top level, and then dividing each functional component at the top level to obtain multiple functional components at the second level, and so on to obtain multi-level functional components, wherein the functional components at the current level refer to the functional components of the non-top level, and the functional components at the current level are obtained by dividing the functional components of the previous level. For example, referring to Figure 5, the harmonic functional component is obtained by dividing the power quality analysis functional component, and is a sub-functional component of the power quality analysis functional component.

[0081] The terminal uses the final multi-level functional components as multiple functional components corresponding to the power business system under the current splitting strategy.

[0082] In this embodiment, for each current splitting strategy, the power business system is split into multiple levels to obtain multi-level functional components. This multi-level splitting method is conducive to splitting the power business system into multiple functional components according to business functional characteristics. The coupling between multiple functional components is low, and larger complex business objects can be processed in a combined manner, and a business organizational structure based on functional components can be obtained, which is conducive to the flexible expansion and change of the power business system.

[0083] In an exemplary embodiment, based on the number of occurrences of each of multiple functional components and multiple component types in the use cases of the power business system under the current split strategy, a split constraint indicator corresponding to the current split strategy is determined, including: determining the functional component sharing degree based on the number of occurrences of each of multiple functional components in the use cases of the power business system under the current split strategy and the number of use cases of the power business system; determining the component type sharing degree based on the number of occurrences of each of multiple component types in the use cases of the power business system under the current split strategy and the number of use cases of the power business system; determining the information exchange degree between the functional components and the component types based on the functional component sharing degree, the component type sharing degree and the shared use cases between the functional components and the component types; determining the information exchange degree between the multiple component types based on the functional component sharing degree, the component type sharing degree and the shared use cases between the multiple component types; using the functional component sharing degree, the component type sharing degree, the information exchange degree between the functional components and the component types and the information exchange degree between the multiple component types as the split constraint indicator corresponding to the current split strategy.

[0084] Among them, the functional component sharing degree is used to measure the degree to which a single functional component is read and written by different use cases. The component type sharing degree is used to measure the degree to which a single component type is read and written by different use cases. The information exchange degree between functional components and component types is used to measure the coupling between functional components and component types. The information exchange degree between multiple component types is used to measure the coupling between multiple component types. The more times the current associated node is a functional component that is called by other functional components, the more information is exchanged between vertices. The terminal uses the above four indicators as split constraint indicators corresponding to the current split strategy.

[0085] In some embodiments, the functional component sharing degree The formula is:

[0086]

[0087] Component type sharing The formula is:

[0088]

[0089] The degree of information exchange between functional components and component types The formula is:

[0090]

[0091] The degree of information exchange between multiple component types The formula is:

[0092]

[0093] in, Indicates component type The number of occurrences in the use case, u represents the number of use cases in the power business system, Representing functional components The number of occurrences in the use case, V represents and or and Shared use cases between Indicates the priority of use case t among all use cases. ; m represents the total number of component types included in use case t; n represents the total number of functional components corresponding to the component types included in use case t.

[0094] In this embodiment, four splitting constraint indicators are determined through the number of occurrences of multiple functional components and multiple component types in the use cases of the power business system under the current splitting strategy, the number of use cases of the power business system, and the shared use cases between nodes. They are the functional component sharing degree, the component type sharing degree, the information exchange degree between functional components and component types, and the information exchange degree between multiple component types. This method for determining the splitting constraint indicators quantifies the coupling between functional components and component types from multiple angles, which is conducive to selecting the splitting combination with the lowest coupling.

[0095] In an exemplary embodiment, based on the internal interaction times and external interaction times corresponding to each of the multiple functional components under the current splitting strategy, a splitting evaluation index corresponding to the current splitting strategy is determined, including: determining the quality of the structured module based on the internal interaction times corresponding to each of the multiple functional components under the current splitting strategy, the external interaction times between the multiple functional components, and the number of components of the multiple functional components; determining the operation call ratio based on the number of calls between the multiple functional components under the current splitting strategy; determining the average entropy based on the number of use cases of each functional component and the number of components of the multiple functional components under the current splitting strategy; determining the interface number index based on the number of interfaces of each functional component under the current splitting strategy; and using the structured module quality, the operation call ratio, the average entropy, and the interface number index as the splitting evaluation index corresponding to the current splitting strategy.

[0096] Among them, the quality of the structural module refers to an indicator that measures the modular quality of functional components from a structural perspective. The greater the quality of the structural module, the better the splitting effect of the power business system.

[0097] In some embodiments, the structured module quality The calculation formula is:

[0098]

[0099] in, represents the number of internal interactions of functional component i, represents the number of external interactions between functional component i and functional component j, represents the number of components of functional component i, represents the number of components of functional component j, N is the number of components of multiple functional components, The higher the value, the better the modularity.

[0100] The run call ratio is used to measure the percentage of run time calls that occur between two functional components i and j. The smaller the value of the run call ratio, the better the splitting effect of the power business system.

[0101] In some embodiments, the calculation formula of the running call ratio ICP is:

[0102]

[0103] in, Represents the number of calls between functional component i and functional component j.

[0104] The average entropy represents the average entropy of multiple functional components contained in each level. The smaller the value of the average entropy is, the better the splitting effect of the power business system is.

[0105] In some embodiments, the calculation formula of the average entropy BCP is:

[0106]

[0107] in, Represents the number of use cases of functional component i.

[0108] The interface quantity indicator is used to measure the number of interfaces in a functional component. The lower the value of the interface quantity indicator, the better the splitting effect of the power business system.

[0109] In some embodiments, the interface quantity indicator is calculated as:

[0110]

[0111] in, is the number of interfaces in functional component i.

[0112] In this embodiment, four splitting evaluation indicators are determined through the internal interaction times and external interaction times corresponding to each functional component under the current splitting strategy, the number of components, the number of calls between multiple functional components, the number of use cases and the number of interfaces of each functional component. They are structured module quality, operation call ratio, average entropy and interface quantity indicators. This method for determining splitting evaluation indicators quantifies the splitting effect of the power business system from multiple angles, which is conducive to selecting the splitting combination with the best splitting effect.

[0113] In an exemplary embodiment, the splitting constraint indicators corresponding to each splitting strategy include the degree of sharing of functional components, the degree of sharing of component types, and the degree of node information exchange; based on the splitting constraint indicators and splitting evaluation indicators corresponding to each of the multiple splitting strategies, a target splitting strategy is determined from the multiple splitting strategies, including: taking the splitting strategies in which the degree of sharing of functional components satisfies the first constraint condition, the degree of sharing of component types satisfies the second constraint condition, and the degree of node information exchange satisfies the third constraint condition as candidate splitting strategies; based on the splitting evaluation indicators, determining the target splitting strategy from the multiple candidate splitting strategies.

[0114] The node information exchange degree includes the information exchange degree between functional components and component types and the information exchange degree between multiple component types.

[0115] In some embodiments, the first constraint may be:

[0116]

[0117] The second constraint can be:

[0118]

[0119] The third constraint can be:

[0120]

[0121]

[0122] The terminal can use the splitting strategies in which the functional component sharing degree satisfies the first constraint condition, the component type sharing degree satisfies the second constraint condition, and the node information exchange degree satisfies the third constraint condition as candidate splitting strategies, and then further select multiple candidate splitting strategies according to the splitting evaluation index to determine the target splitting strategy.

[0123] In this embodiment, by determining whether the functional component sharing degree, component type sharing degree and node information exchange degree of each of the multiple splitting strategies meet the corresponding constraints, the candidate splitting strategy is determined, and then the target splitting strategy is further determined based on the splitting evaluation index, which is conducive to gradually selecting the optimal target splitting strategy, thereby reducing the coupling between business functions.

[0124] In an exemplary embodiment, the splitting evaluation indicators corresponding to each splitting strategy include structured module quality, operation call ratio, average entropy and interface quantity indicators; based on the splitting evaluation indicators, a target splitting strategy is determined from multiple candidate splitting strategies, including: for each candidate splitting strategy, the structured module quality, operation call ratio, average entropy and interface quantity indicators of the current candidate splitting strategy are weighted and summed to obtain an evaluation score corresponding to the current splitting strategy; the candidate splitting strategy with the highest evaluation score among the multiple candidate splitting strategies is used as the target splitting strategy.

[0125] Among them, since multiple split evaluation indicators have different value ranges, the values ​​of all split evaluation indicators can be normalized. The split evaluation indicator value of the current edge is divided by the maximum value of the corresponding split evaluation indicator in all splittable schemes, and the result is used as the value of the final split evaluation indicator. Moreover, according to the needs of specific scenarios, the weights of indicators such as SM, ICP, BCP, IFN, etc. can be set to generate power business system split calculation schemes for distribution substations in different scenarios to adapt to complex power business application scenarios.

[0126] In some embodiments, the evaluation score The calculation formula is:

[0127]

[0128] in, , , , They represent the weights of SM, ICP, BCP and IFN indicators respectively.

[0129] In this embodiment, multiple split evaluation indicators are evaluated by weighted sum calculation, so that the candidate split strategy with the highest evaluation score is used as the target split strategy, which is conducive to determining the target split strategy with the lowest coupling and the best split effect.
