Abstract
As the integrated energy system (IES) develops rapidly, multiple advanced components has been put into use in the smart power distribution system (SPDS). Facing challenges brought by massive heterogeneous data, complex information interaction and usage of diversified intelligent devices, how to allocate the limited resources of the communication network efficiently to fulfill the application demand is becoming an urgent issue. In this paper, the performance of the communication network during the SPDS operation is analyzed. Firstly, a communication network architecture based on the internet of things (IoT) technology was introduced and its applications and quality of service (QoS) requirements in SPDS are characterized. Followed by a proposed bandwidth model based on queueing theory, through which the predicted bandwidth scheme for data acquisition application considering QoS is obtained. Finally, a smart distribution station is taken as an example, where the network performance is analyzed considering three typical scenarios. The OPNET-based simulations are conducted to verify the rationality and effectiveness of the proposed method.
