Abstract
With the development of smart grids and active distribution networks (ADNs), reliable and low-latency communication is the key to advanced applications such as energy management and situation awareness (SA). However, with the increasing amount of data and location information to be collected, ensuring the real-time transmission of sampling data has become a challenge. In addition, the operating environment of ADNs is complex, and external interference will affect the reliability of transmission. In particular, the occurrence of power emergencies is random, and the high reliability of emergency data transmission caused by emergencies has attracted much attention. Although repeated data transmission in 5G machine-type communication (MTC) can improve the reliability, how to dynamically allocate communication resources according to the transmitted data and external interference remains a problem. To this end, we propose a scheme of repeated data transmission to eliminate the influence of external interference on the outage probability of emergency data transmission. Our scheme is modeled as a dynamic programming problem to maximize the energy efficiency. First, external interference is considered in the calculation of the transmission outage probability of smart meters (SMs), and the number of repeated transmissions of emergency data is placed in the position of the index, which is determined by reaching the target outage probability. Then, to allocate dynamic resource in real time in a changing environment, we propose a deep reinforcement learning method, which has fast computing speed, can more quickly allocate resources and reduce the delay of data transmission. Simulation results have verified the superiority of the proposed scheme.
