| With the continuous promotion of the national energy revolution,the continuous optimization and upgrading of the industrial structure,the continuous increase of electricity demand and other factors,the load characteristics of the power grid has also undergone profound changes,showing a significant "peak" characteristics.Under the new power system with new energy as the main body,power demand response(DR)is an important means to strengthen the active load regulation ability and realize the friendly interaction between supply and demand,as well as a key way to promote "carbon peak and carbon neutrality".The flexible implementation of normalized DR Depends on a large number of efficient and reliable information interactions,but limited communication resources can hardly guarantee the reliable transmission of large-scale DR Service data.Based on DR Business information flow characteristics and DR Business process differentiation requirements,this paper optimizes DR Business information transmission process.Specific work is as follows:Firstly,the types and response characteristics of demand side resources are analyzed,the hierarchical architecture and key communication technologies of demand response communication system are studied,and then the demand response information interaction model and typical interaction scenarios are constructed.According to the communication and transmission requirements of different DR Grid services and DR Information interaction services,the service characteristics are analyzed and different service levels are divided to determine the optimization focus of this paper,which provides a theoretical basis for the research of the following chapters.Secondly,according to the typical traffic aggregation characteristics of DR Information flow,an aggregation traffic optimization mechanism for DR Data flow is proposed.Based on the batch merging and redundancy reduction processing of highly concurrent service aggregation data,a convergence traffic optimization mechanism based on time window is designed,which can effectively reduce the amount of data transmission and improve the overall transmission efficiency of demand response service information.Finally,an adaptive transmission strategy for DR Service differentiation is proposed.The precoding technology is used to optimize the reliability of DR Communication transmission.The information interaction characteristic requirements of each period in the implementation of DR And the algorithm performance characteristics of different precoding schemes are analyzed respectively,and the technology matching between different DR Periods and precoding schemes is carried out.This strategy can comprehensively consider the service requirements of different DR Periods,ensuring the quality of key information exchange and efficient utilization of computing resources. |
