Modeling and Performance Analysis of Communication Network of Intelligent Power Distribution System
As integrated energy systems(IES)continue to evolve,more and more advanced equipment and components are integrated into smart power distribution system(SPDS),accompanied by the technical challenges brought by diversified information interaction,massive complex data and the use of advanced intelligent equipment.Therefore,how to meet the needs of various applications within the limited communication network resources has become a key problem.Requirements of various applications in the SPDS on the performance of the communication network are first analyzed,then a communication network architecture based on Internet of Things technology is proposed,and its application and quality of service(QoS)requirements in intelligent distribution system are described.Furthermore,a bandwidth pre-diction method for data acquisition applications considering QoS is proposed based on the bandwidth model of queuing theory.Finally,the network performance of three typical application scenarios is analyzed,and the rationality and effectiveness of the proposed method are ver-ified through OPNET simulation.
