摘要:

针对传统的电能质量分析需要在低压侧部署大量的监测站,且对通信通道和计算设备的数据传输能力及计算能力有一定要求,提出一种计及边缘计算任务分配优化的电能质量分析方法。首先构建云边协同模式下的电能质量分析系统框架,将电能质量分析算法希尔伯特-黄变换(HHT)部署于边缘层,从而构建一种基于边缘计算的电能质量分析模型;然后分析电能质量监测的任务分配问题,利用遗传算法对其进行求解,生成最优任务分配策略。以某一台区下的电能数据为例,验证了所提方法的可靠性和准确性,同时将任务分配优化后的结果和现有方法对比,所提方法具有更低的能效代价,可广泛应用于实际工程。

Abstract:

Systematic power quality analysis requires the deployment of a large number of monitoring stations on the low voltage side,and there are certain requirements for the data transmission and computing capabilities of communication channels and computing equipment.To this end,this paper proposed a power quality analysis method that takes into account the optimization of edge computing task allocation.First,it builds a power quality analysis system framework under the cloud-side collaboration mode,deploys the power quality analysis algorithm Hilbert-Huang Transform (HHT) at the edge layer,thereby building a power quality analysis model based on edge computing.Then the task allocation problem of power quality monitor is analyzed,the genetic algorithm is used to solve it,and to generate the optimal task allocation strategy.Taking the electric energy data under a certain area as an example,the reliability and accuracy of the analysis method in this paper are verified.At the same time,the results of task allocation optimization are compared with the existing methods.The optimization method in this paper has a lower energy efficiency cost and can be widely used in actual engineering.
