边缘协作与中继辅助联合架构的分布式能源系统信息传输优化方法
Information Transmission Optimization for Distributed Energy Systems via Edge Collaboration and Relay Assistance Joint Architecture
摘要
Abstract
With the surge in data transmission volume from physical terminals in distributed energy systems,the accuracy of data transmission and the rationality of communication task allocation face significant challenges.To address these issues,this paper proposes an optimization method for information transmission in distributed energy systems based on joint edge collaboration and relay assistance architecture.Firstly,a joint edge collaboration and relay-assistance communication network architecture for distributed energy systems is proposed,mitigating communication resource location imbalance by having relay assistance undertake tasks and enabling task collaboration between adjacent energy bodies.Secondly,a five-slot information transmission architecture based on non-orthogonal multiple access(NOMA)technology and an energy consumption cost representation method are proposed to solve the quantification problem of communication costs by modeling the overall transmission process of the five-slot information.Thirdly,a collaboration assistance computing and resource allocation algorithm is proposed to minimize communication costs by optimizing relay power,execution time,and task allocation.Finally,the proposed communication framework and optimization strategy are tested on a distributed energy system in China.The results demonstrate that the proposed approach can effectively promote the reasonable allocation of communication resource and can significantly reduce communication costs.关键词
