With the increasing complexity of power systems, communication networks are taking on more and more tasks. They not only need to support conventional power dispatching, control and data transmission, but also need to cope with multi-dimensional communication needs such as power load forecasting, equipment monitoring, fault detection, and system optimization. The communication demand of power services has significant multi-time and space scale distribution characteristics. In terms of time and space scale, the communication load is not only affected by the time period and geographical location, but also highly coupled with factors such as changes in power load, weather changes, and equipment operating status. This complex and changeable characteristic makes the power communication demand show significant time-varying and spatial heterogeneity. Communication demand not only fluctuates in daily operation, but also surges sharply when special events (such as fault handling, load dispatching, disaster emergency, etc.) occur.

[0069] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0070] Reference Figure 1 , Figure 1 It is a schematic diagram of the structure of a new type of power system satellite-ground fusion communication load modeling and situation awareness equipment in the hardware operating environment involved in the embodiment of the present invention.

The memory 1005 may also be a storage system independent of the aforementioned processor 1001.

[0072] Those skilled in the art will understand that Figure 1 The structure shown in the figure does not constitute a limitation on the new power system satellite-ground fusion communication load modeling and situational awareness equipment, and may include more or less components than shown in the figure, or combine certain components, or arrange the components differently.

[0073] like Figure 1 As shown, the memory 1005 as a computer-readable storage medium may include an operating system, a network communication module, a user interface module, and a new power system satellite-ground fusion communication load modeling and situation awareness program.

[0074] exist Figure 1 In the new type of power system satellite-ground fusion communication load modeling and situation awareness device shown, the network interface 1004 is mainly used for data communication with the network server; the user interface 1003 is mainly used for data interaction with the user; the processor 1001 and the memory 1005 in the new type of power system satellite-ground fusion communication load modeling and situation awareness device of the present invention can be set in the new type of power system satellite-ground fusion communication load modeling and situation awareness device, and the new type of power system satellite-ground fusion communication load modeling and situation awareness device calls the new type of power system satellite-ground fusion communication load modeling and situation awareness program stored in the memory 1005 through the processor 1001, and executes the new type of power system satellite-ground fusion communication load modeling and situation awareness method provided in the embodiment of the present invention.

[0075] The embodiment of the present invention provides a novel power system satellite-ground fusion communication load modeling and situation awareness method, referring to Figure 2 , Figure 2 It is a flow chart of the first embodiment of the novel power system satellite-ground fusion communication load modeling and situation awareness method of the present invention.

[0076] In this embodiment, the novel power system satellite-ground fusion communication load modeling and situation awareness method includes the following steps:

[0077] Step S10: classifying the communication loads of each communication node in the satellite-ground integrated new power system based on the load characteristic information of the communication loads, and obtaining load classification results.

[0078] It should be noted that the execution subject of this embodiment may be a computing service device with data processing, network communication and program running functions, such as a computer, etc., or a terminal electronic device capable of realizing the above functions, etc. The following takes a new type of power system satellite-ground fusion communication load modeling and situation awareness device (referred to as the awareness device) as an example to illustrate this embodiment and the following embodiments.

[0079] It should be noted that the load characteristic information may include demand response characteristics, timeliness characteristics, communication mode characteristics and urgency characteristics of the communication load.

[0080] In some embodiments, the sensing device may classify the communication load from multiple dimensions, for example, according to demand response, it may be classified into basic communication load, reducible communication load, shiftable communication load, and transferable communication load.

[0081] The above basic communication loads can be the core and uninterruptible communication requirements in the power system. They usually need to ensure connection and stable transmission at all times in any situation of the satellite-ground fusion network, and have high priority. Even in the case of tight load or high network latency, the load requirements of these communications cannot be reduced. For example, real-time control information in the power dispatching system and the status and fault alarm data transmission of generator sets and substations.

[0082] The above-mentioned communication load that can be reduced can be those communication flows that can be partially interrupted or reduced in load usage when necessary. This type of load has a certain degree of flexibility and can be partially or completely reduced when the load demand is high. Usually, this type of load can tolerate interruption or reduced transmission rate, but it will have a certain impact on the efficiency of the system or user experience. Its reduction will be dynamically adjusted according to the supply and demand of load resources. For example, the resolution of a video conference can be adjusted to reduce load occupancy.

[0083] The above-mentioned shiftable communication load can be that the load power supply time can be changed according to the plan, the load needs to be shifted as a whole, and the power consumption time spans multiple scheduling periods. For drone inspections, some data transmission tasks can be performed within a fixed time, but the data volume cannot be interrupted or adjusted. The transmission of data can only be adjusted according to the plan, but the size or flow of the transmission content cannot be adjusted.

[0084] The above-mentioned transferable communication load can be a flexible adjustment of the power consumption in each time period, but the total load of the entire cycle after the transfer must remain unchanged from that before the transfer. For example, during the peak communication period, some low-priority data flows can be suspended or the transmission rate can be reduced, and they can be transferred to the off-peak period for uploading, thereby optimizing the use of load resources.

[0085] In some embodiments, the sensing device can be divided into real-time communication load, quasi-real-time communication load and non-real-time communication load according to timeliness.

[0086] The above-mentioned real-time communication loads can be those with extremely high latency requirements, requiring the network to be able to transmit data with the lowest latency. Although the latency of satellite links is large, real-time performance is still crucial for specific critical tasks, especially when there are multiple communication links in the network, and seamless switching between satellite and ground networks must be ensured. For example, emergency dispatch commands and real-time data transmission in power systems.

[0087] The above-mentioned quasi-real-time communication load can be a load that has a certain tolerance for delay but still needs to be transmitted in a relatively short time, mainly transferable communication load and shiftable communication load. It is suitable for applications that do not require instantaneous response but still need to respond in time. For example, the status update of power equipment usually transmits data once a minute or hour.

[0088] The above non-real-time communication loads may have low latency requirements and can tolerate longer delays, mainly transferable communication loads and translatable communication loads. They are usually used for tasks such as batch processing, file transfer or data archiving, such as the backup and transmission of some power big data.

[0089] In some embodiments, the sensing devices can be divided into satellite communication load, ground communication load and hybrid communication load according to the communication mode.

[0090] The satellite communication loads mentioned above may be communications that are usually conducted via satellite links, which have large delays and load limitations and are usually very important in remote areas and disaster situations, such as power data acquisition and control in remote areas.

[0091] The above-mentioned ground communication load can be mainly transmitted through the ground network. This type of load has a lower latency and a higher load, and is therefore usually used for daily power system operation and management, such as power dispatching data within a city or region.

[0092] The above hybrid communication load can be a load that requires the use of satellite and ground communication links at the same time. It is usually used for applications that require wide coverage and high reliability. For example, emergency communications in the post-disaster recovery phase, satellite and ground networks work together.

[0093] In some embodiments, the sensing equipment can be divided into emergency communication load and normal communication load according to the degree of urgency.

[0094] The above-mentioned normal communication load may be the communication demand that needs to be met during daily and normal operations, which is mainly ground communication load, and also includes satellite communication load and hybrid communication load.

[0095] The above emergency communication load can be the communication demand that needs to be responded quickly in the event of a disaster or other emergency, mainly satellite communication load. Since satellite networks have the advantages of global coverage and independence from ground networks, satellite links are usually used as backup communication means when disasters occur, and can continue to provide services independently of ground networks. Satellite communications will become a key means of emergency communications.

[0096] Step S20: constructing a communication load model corresponding to each load type according to the load classification result.

[0097] It should be noted that the communication load model can be a multi-time and space scale electric power business satellite-ground integrated communication load mathematical model.

[0098] In the specific implementation, the sensing equipment can design a load analysis framework for multi-scale space-time fusion, analyze the distribution characteristics and evolution laws of the satellite-ground fusion communication load of the power business at multiple space-time scales, combine the dynamic evolution characteristics of multiple loads, and establish a mathematical model of the satellite-ground fusion communication load of the power business at multiple space-time scales, providing a theoretical basis for the aggregation of power business communication loads.

[0099] Furthermore, in order to accurately construct the communication load model and provide an accurate theoretical basis for the aggregation of power business communication load, Figure 3 , Figure 3 This is a flow chart of building a communication load model in an embodiment of the present invention. The above step S20 may include:

[0100] Step S201: Obtain the load demand data volume, time demand information and space demand information of each load type;

[0101] Step S202: generating load distribution constraint conditions corresponding to each load type according to the load demand data volume, time demand information and space demand information;

[0102] Step S203: constructing a communication load model corresponding to each load type based on the load distribution constraint condition.

[0103] It should be noted that the load classification result includes the demand response classification result, the load types in the demand response classification result include shiftable communication load, transferable communication load and reducible communication load, and the communication load model includes a shiftable communication load model, a transferable communication load model and a reducible communication load model. The load distribution constraint condition includes a data volume constraint condition, a distribution time constraint condition and a distribution space constraint condition.

[0104] In some embodiments, constructing a translatable communication load model may include: assuming that in multiple regions Data transmission is performed in each area. In time period The load demand is , the total amount of data in each region is , then there exists:

[0105]

[0106] Spatial load translation constraint: Between different regions, the load can be translated in time, but the amount of data in each region remains unchanged. The constraints are:

[0107]

[0108] The load demand of each area cannot be changed: The load demand of each area It can only be adjusted in different time periods and its total demand cannot be changed. Its constraints are:

[0109]

[0110] In some embodiments, constructing a transferable communication load model may include: assuming that the total load demand Can be used in multiple spatial areas and time period Each area In the period The load demand is , the amount of data in each region is , and the total load demand and total data volume remain unchanged during the transfer process, then:

[0111]

[0112] Spatial and temporal load balancing constraints: The load and data volume of each region can be flexibly adjusted in different time periods, but the total load and total data volume remain unchanged. The constraints are:

[0113]

[0114] Flexible adjustment of load and data transmission volume: The load and data volume of each area and time period can be flexibly adjusted to ensure network load balance. The constraints are:

[0115]

[0116] In some embodiments, constructing a model for reducing communication load may include: setting each area In time period The load demand is , the data transmission volume in each period is , and load demand can be reduced in some areas. If the total load demand and data volume remain consistent, then:

[0117]

[0118] The curtailable communication load model may include load curtailment constraints, allowing load demand in certain areas to be curtailed. The load can be reduced in some periods of time. The constraints are:

[0119]

[0120] The curtailable communication load model may include load interruption constraints, where certain tasks may be suspended in certain areas and load demands may be zero.

[0121] Step S30: generating a load demand regulation strategy according to the response characteristic information of the communication load.

[0122] It should be noted that the response characteristic information includes driving characteristics, response period characteristics and response speed characteristics.

[0123] In the specific implementation, the sensing device can analyze the communication load demand response mechanism of the power business based on load characteristics such as communication load driving mode, response period, and response speed, and generate a load demand control strategy for the power business that can be dynamically adjusted during load fluctuation periods.

[0124] In some embodiments, the load demand regulation strategy can be divided into incentive-based demand response and price-based demand response based on the driving mode. For incentive-based demand response, users can be attracted to participate in the communication load reduction project required by the system by adopting incentive policies and compensation methods. For example, during the peak period of communication load, operators can encourage users to adjust their communication behavior or reduce the amount of data transmission through price discounts, point rewards, or cash rewards. Users reduce load demand by adjusting usage time, delaying non-important communication tasks, or using local cache, thereby obtaining "compensation" provided by operators. For price-based demand response, user behavior is guided by dynamically adjusting communication costs. Similar to the peak and valley mechanism of time-of-use electricity prices, operators can use different pricing strategies, such as real-time traffic rates, time-divided data charges, etc., to allow users to adjust their communication behavior in different time periods. For example, during peak load periods, operators increase data transmission fees to encourage users to reduce load usage; while during load trough periods, operators provide lower traffic fees to attract users to increase load demand.

[0125] In some embodiments, the load demand regulation strategy can be divided into peak-shaving demand response and valley-filling demand response based on the response period. For peak-shaving demand response, users are required to reduce load usage during the peak period of communication load. Operators can encourage users to postpone large data transmission or adjust the load occupancy of applications by informing users of the expected peak period in advance or providing relevant incentives during the peak period. Network intelligent scheduling technology can be combined to allow users to automatically adjust data transmission time to avoid occupying a large amount of load resources during peak periods. For valley-filling demand response, users are encouraged to increase data transmission during load trough periods. For example, operators can encourage users to perform non-real-time, low-priority file downloads or data backups during load trough periods (such as late at night or non-peak hours on weekdays). This type of demand response can encourage users to increase load demand during trough periods through price discounts or point rewards, thereby balancing the overall network load.

[0126] In some embodiments, the load demand regulation strategy can be divided into scheduled demand response and real-time demand response based on the response speed. For scheduled demand response, the operator can send communication load demand information to users through the platform (such as SMS, application notification, etc.) in advance to inform users of the communication demand and load requirements for a specific period of time. Users can adjust the data transmission volume independently according to the notification to ensure that the load will not be overloaded during the specified period. Operators can optimize the allocation of load resources based on the timeliness and response volume of user responses. For example, the earlier the user responds, the more likely they are to receive more compensation. For real-time demand response, when an emergency occurs in the network, the operator can send an emergency communication load adjustment instruction to the user within a short time (for example, within 30 minutes or 1 minute), requiring the user to reduce load occupancy or postpone the transmission of non-emergency data. In order to cope with sudden peaks in communication demand, user equipment needs to have a certain degree of flexibility, such as automatically adjusting data traffic or automatically limiting load usage through smart terminals to cooperate with emergency adjustments of the network. The key to real-time communication demand response is to achieve rapid feedback and instant control to ensure that the network load can be quickly reduced in an emergency to avoid network congestion or communication interruption.

[0127] Step S40: Aggregating the communication load based on the communication load model and the load demand regulation strategy to obtain a communication load aggregation result.

[0128] It should be noted that aggregating the communication load may include time aggregation and space aggregation. The communication load aggregation result includes multiple aggregated loads, and the aggregated load includes a time aggregated load and a space aggregated load.
