摘要
近年来随着电力电子设备的高比例接入
配电系统边缘侧数据规模骤增
自适应压缩感知逐渐成为缓解云边带宽压力的关键技术之一
对应的配电主站需对其合理解压以满足差异化业务时延要求
为此提出一种适应边缘侧动态压缩感知的配电主站算力资源自适应分配方法。首先
建立基于算力资源驱动的配电主站解压系统模型。然后
考虑差异化业务时延要求设计算力资源分配收益函数
据此设计对应优化问题。最后
将原始优化问题解耦为算力资源分配层和时间断面设置层
采用KKT(Karush-Kuhn-Tucker)条件及变步长重分配机制分别求解各层对应子问题
进而实现对原始优化问题的高效求解。仿真分析表明
所提方法可通过独特的变步长重分配机制充分发掘算力资源分配效用
灵活适应边缘侧动态压缩过程
保障配电主站对边缘侧的状态感知能力。
Abstract
In recent years
with the high proportion of power electronic equipment access
the data scale on the edge side of the power distribution system has increased sharply. Adaptive compressed sensing has gradually become one of the key technologies to alleviate the bandwidth pressure on the cloud edge. The corresponding distribution master station needs to reasonably decompress it to meet the delay requirements of differentiated business. Therefore
an adaptive allocation method of computing power resources for distribution master station adapted to the dynamic compressed sensing on the edge side is proposed. Firstly
a distribution master station decompression system model driven by computing power resources is established. Then
considering the differentiated business delay requirements
a computing power resource allocation revenue function is designed
and based on this
the corresponding optimization problem is designed. Finally
the original optimization problem is decoupled into the computing power resource allocation layer and the time section setting layer. The KKT(Karush-Kuhn-Tucker) condition and the variable step size reallocation mechanism are adopted to solve the corresponding sub-problems of each layer respectively
thereby achieving efficient solution of the original optimization problem. Simulation analysis shows that the proposed method can fully explore the utility of computing power resource allocation through a unique variable step size reallocation mechanism
flexibly adapt to the dynamic compression process on the edge side
and ensure the state perception ability of the distribution master station on the edge side.
