摘　　要：考虑到传统配电通信网对新型业务流支撑能力不足,结合运营商公网的跨域融合组网模式被广泛应用。其中,资源预留是提升数据传输确定性的重要技术,但公网通道性能存在不可预知的波动性,对基于有交互模式的资源预留效用影响机理难以量化表征。为此,提出面向海量分布式新能源业务流的通存资源无交互协同预留算法。首先,采用通感算一体化模式,基于业务流特征构建异质资源无交互协同预留系统模型;其次,设计对应无交互协同预留效用函数,并以效用最大化为目标提出对应优化问题;最后,基于块坐标下降法将原问题解耦,结合凸优化理论快速给出最优无交互资源预留方案。仿真结果表明,所提业务流特征评估方法能够合理量化表征通道性能波动性,进而在无交互模式下有效优化异质资源协同预留过程,显著提升海量分布式光伏数据感知确定性。Considering the insufficient support capability of traditional distribution communication networks for new types of service flows,the cross-domain integrated networking model,which combines the public networks of operators,has been widely applied.Among them,resource reservation is an important technique to enhance the certainty of data transmission.However,the performance of public network channels has unpredictable fluctuations,making it difficult to quantify the impact mechanism of the utility of resource reservation based on interactive modes.Therefore,an interaction-free cooperative reservation algorithm of communication-cache resources for massively distributed renewable energy service flow is proposed.Firstly,the passive-sensitive arithmetic integration mode based on service flow characteristics is used to construct an interaction-free cooperative reservation system model for heterogeneous resources.Secondly,a corresponding interaction-free cooperative reservation utility function is designed,and the corresponding optimization problem is proposed with the objective of maximizing utility.Finally,the original problem is decoupled using the block coordinate descent method,and the optimal interaction-free resource reservation scheme is quickly obtained through convex optimization theory.Simulation results demonstrate that the proposed method for assessing service flow characteristics can reasonably quantify the fluctuations of channel performance and effectively optimize the cooperative reservation process of heterogeneous resources in an interaction-free mode,thus significantly enhancing the perception certainty of massively distributed photovoltaic data.
