Embodiment 2

[0036] Embodiment 2 of a load balancing method for a power system cloud platform based on fuzzy comprehensive evaluation, comprising:

[0037] S21: Comprehensively consider the performance index that characterizes the server load characteristics, and use it as the evaluation factor of the load situation evaluation to conduct an overall evaluation, and determine the comprehensive evaluation factor set U of the server load situation in the power system cloud platform. U=(u1,u2,...ui...um), where the element ui is the i-th factor affecting the evaluation object.

[0038] In this embodiment, the comprehensive evaluation factor set U=(u1, u2, u3, u4) can be set, where u1 represents the CPU availability of the server, u2 represents the memory availability of the server, and u3 represents the hard disk storage of the server Availability, u4 indicates the bandwidth availability of the server.

[0039] S22: Establish a comprehensive evaluation evaluation set V=(v1,v2,...vj...,vn) acco...

Abstract

The invention discloses an electric power system cloud platform load balancing method based on fuzzy comprehensive evaluation, and the method comprises the steps: comprehensively considering a plurality of performance indexes representing the load characteristics of a server, and taking the performance indexes as a plurality of evaluation factors for load condition evaluation to carry out the overall evaluation; establishing a comprehensive evaluation comment set according to the task allocation requirement; determining a membership function of each factor to the comment set, and obtaining a single-factor evaluation matrix corresponding to the server load according to the membership function; and finally, performing multi-factor comprehensive evaluation on the server load according to theset factor weight vector and the single-factor evaluation matrix, and allocating the current task to the server with the highest relative membership comment according to an evaluation result. According to the method, the performance of the server can be accurately evaluated, the real-time performance is high, each factor of the load performance of the server is effectively considered, and the problem of load balance of a large-scale server cluster can be solved.

Description

technical field [0001] The invention relates to the field of power system analysis cloud computing, in particular to a load balancing method for a power system cloud platform based on fuzzy comprehensive evaluation. Background technique [0002] With the advent of the power Internet of Things, the real-time server load balancing problem of the power cloud platform is becoming more and more prominent. How to realize the real-time response to a large number of clients in the background server network; with the development of automation, when the number of remote switches soars, what they control How to support the back-end service can make the switch control delay unacceptable; and the real-time calculation and analysis of the power grid, etc., all require a real-time server network, and they all need to respond quickly to user requests, that is to say, they all require the back-end Server load balancing. The above servers have common characteristics: the client is huge and m...
