Communication bandwidth prediction based on smart distribution grid service level

Abstract

Aiming at the problem that the bandwidth utilization of current current service bandwidth calculation method is not high, a bandwidth calculation method based on queuing theory is proposed. From the perspective of macro service security level, different levels of bandwidth prediction are performed for services of different security levels. The bandwidth prediction model for different levels of service processing is built. Finally, based on the bandwidth prediction model, the optimal transmission efficiency bandwidth prediction calculation method for the service node queuing theory is proposed, and the example of the typical distribution electric information collection service of the national grid is adopted. Compared with the current elastic coefficient bandwidth prediction method, the effectiveness of the proposed method is verified.
