Specifically, similar technical solutions are given in the invention patent applications CN202211087275.4 "A multi-regional power system distributed frequency modulation method considering communication network optimization" and CN202410433626.5 "A power system control method and device considering 5G communication random delay". However, the above technical solutions all ignore the following technical problems:
[0003] When generating dispatch instructions, there are certain differences in the power supply topology and power distribution of power systems in different regions, and there are certain differences in the changes in power load of power users in power systems in different regions. This leads to large differences in the load dispatch requirements and processing complexity of power systems in different regions. Therefore, if a communication network is used for unified optimization and dispatch management, the generation and processing efficiency of dispatch instructions may be slow and unable to meet the requirements of power system operation reliability.
[0004] In view of the above technical problems, the present invention provides a power system control method and system based on a communication network. Summary of the invention

In the present invention, the historical delay data of the communication network of different load scheduling targets is used to determine whether the response delay of the scheduling instructions of the scheduling sub-area can meet the requirements, thereby achieving accurate evaluation of the response delay of the scheduling instructions of the scheduling sub-area from the perspective of the scheduling delay of different load scheduling targets, avoiding the technical problem that the generation and processing efficiency of the scheduling strategy does not meet the requirements due to the response delay, and improving the scheduling control efficiency and operation stability of the scheduling sub-area.
[0013] 2. In the present invention, the dispatching control of the power system is carried out according to the dispatching sub-nodes and the dispatching center, which not only realizes the efficiency and accuracy of the dispatching processing of part of the dispatching sub-areas through the dispatching sub-nodes, but also ensures the systematic and holistic nature of the dispatching processing of the power system by further combining with the dispatching center, thereby improving the stability of the operation of the overall power system.
[0014] A further technical solution is that the dispatching sub-areas of the power system are divided according to preset areas or cities.

[0019] Based on the number of the delayed scheduling targets, it is determined whether the response delay of the scheduling instruction of the scheduling sub-area can meet the requirement.
[0020] A further technical solution is that the difficulty of generating and processing the scheduling instructions of the scheduling sub-area ranges from 0 to 1, wherein the greater the difficulty of generating and processing the scheduling instructions of the scheduling sub-area, the greater the difficulty of generating and processing the scheduling instructions of the scheduling sub-area.

[0031] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.
[0032] The terms "a", "an", "the", and "said" are used to indicate the presence of one or more elements / components / etc.; the terms "comprising" and "having" are used to express an open-ended inclusive meaning and mean that additional elements / components / etc. may be present in addition to the listed elements / components / etc.
[0033] When generating dispatch instructions, due to the differences in power supply topology and power distribution of power systems in different regions, as well as the differences in changes in power load of power users in power systems in different regions, it is necessary to determine whether to use the setting of dispatch sub-nodes according to the needs of different regions, so as to improve the efficiency and reliability of load dispatch processing.
[0034] Specifically, in the present application, the scheduling sub-area that needs to be set up for the scheduling sub-node is determined by the response delay of the scheduling instructions of different scheduling sub-areas, the difficulty of generating and processing the scheduling quality, etc., the scheduling sub-area is controlled according to the scheduling sub-node, and the communication network is used to realize unified scheduling control processing of different scheduling sub-nodes and the unified scheduling management platform.
[0035] Response delay: It is determined based on the average value of historical delays. When the response delay of a scheduling sub-area is greater than 30s, it is determined that the response delay cannot meet the requirements, and it is determined to be a scheduling sub-area that needs to construct a scheduling sub-node.
[0036] Generation processing difficulty: It is determined based on the distribution data of different types of load scheduling targets in the power supply topology. Specifically, the generation processing difficulty is determined by multiplying the number of load scheduling targets by a preset proportional factor. For example, when the number of load scheduling targets is 30, the generation processing difficulty is 30 multiplied by 0.1, which is 3.
[0037] The scheduling sub-region constructed by the scheduling sub-node that needs to issue scheduling instructions is determined based on the product of the duration of historical load balancing deviations and the difficulty of generating and processing scheduling instructions. When the duration of historical load balancing deviations is 0.1 and the generation and processing difficulty is 0.3, the product is 0.03. When it is greater than 0.02, it is a scheduling sub-region constructed by the scheduling sub-node that needs to issue scheduling instructions.

[0054] S11 determines the communication delays of different load dispatching targets at different load dispatching times according to the historical delay data of the communication network of different load dispatching targets, and judges whether there is a load dispatching target whose communication delay is greater than the preset delay threshold in different load dispatching times. If not, proceed to the next step. If yes, proceed to step S13.

If so, proceed to the next step. If not, determine that the response delay of the dispatching instruction of the dispatching sub-area cannot meet the requirements.
