Problems solved by technology

If you replace the power system computing equipment one by one, it will take a lot of manpower and financial resources; but adding cloud servers and offloading the computing load to cloud servers only needs to increase the cost of cloud servers, so this method is widely used

specific Embodiment 1

[0040] The power system load unloading method of this embodiment, the flowchart is as follows figure 1 shown. The uninstallation method includes the following steps:

[0041] Step a. Calculate the load of each power system;

[0042] Step b, carry out naturalization processing to all the calculation results obtained in step a;

[0043] Step c, perform parameterization processing on the naturalization processing result obtained in step b;

[0044] Step d, according to the parameterization processing result obtained in step c, determine the priority of each power system, and unload to the cloud server in descending order of priority.

specific Embodiment 2

[0045] On the basis of the specific embodiment 1, the method for unloading the load of the power system in the present embodiment further defines step a as specifically:

[0046] Step a1. There are m tasks in the ith power system, and the importance of each task is scored. The scores of these tasks are: r 1 , r 2 , …, r m , the higher the score, the higher the task priority;

[0047] Step a2: Perform weighted superposition on all tasks to obtain the task score:

[0048] A=k 1 r 1 +k 2 r 2 +…+k m r m

[0049] where k j is the weight of the jth task, and the final result of the task score of the ith power system is recorded as A i .

[0050] This embodiment not only obtains the overall score of a power system, but also records the priority of each task in each power system according to the weight. On the cloud server side, the execution order of each task can be refined to improve the cloud The computational efficiency of the server.

specific Embodiment 3

[0051] On the basis of the specific embodiment 1, the method for unloading the load of the power system in this embodiment further defines step b as specifically:

[0052] Judgment max[A 1 , A 2 , …, A n ] is greater than 2 35 -1 if:

[0053] Yes, then B i =A i

[0054] otherwise

[0055] The final normalized result of the task score of the i-th power system is recorded as B i .

[0056] This embodiment provides a specific algorithm for the normalization operation.

Abstract

A load unloading method for a power system of the present invention relates to electric power technology, and specifically relates to a load unloading algorithm; the method first calculates the load of each power system, then performs naturalization processing on all calculation results obtained, and then naturalizes The processing results are parameterized, and finally according to the parameterized processing results, the priority of each power system is judged, and the order of priority from large to small is unloaded to the cloud server; the power system load unloading method of the present invention can calculate and obtain each power system The system calculates the priority of the load, and then obtains the order of unloading to the cloud server to ensure that the calculation load of each power system is carried out in an orderly manner.

Description

technical field [0001] The present invention relates to a load unloading method for a power system, which relates to power technology, in particular to a load unloading algorithm. Background technique [0002] As power systems become more complex, their computational tasks increase exponentially. If the power system computing equipment is replaced one by one, it will cost a lot of human and financial resources; while adding a cloud server, offloading the computing load to the cloud server, only needs to increase the cost of the cloud server, so this method is widely used. [0003] Since there are many power systems that need to perform load shedding, arranging the priorities of these power systems has become a key technical problem to be solved urgently in the art. SUMMARY OF THE INVENTION [0004] In view of the above technical requirements, the present invention discloses a load unloading method for a power system. The method can calculate the priority of each power sys...
