Evolution analysis of power wireless private networks for control services

With the in-depth advancement of energy IoT and power IoT, the application of wireless communication technology in the power industry has received more and more attention. Combined with the future new power system control service communication demand, the evolution direction of power wireless private network bearing control service was analyzed. The key technologies of power wireless private network based on its own frequency band and based on unauthorized frequency band were discussed respectively. High-quality service communication and high-efficiency spectrum utilization were taken by the former as the purpose of evolution, and technologies such as low-latency forwarding, interference suppression, and spectrum sharing mechanism needed to be introduced. The edge control network was focused on by the latter, and the emerging IoT technologies for the evolution were integrated, including but not limited to, the terminal pass-through, and narrowband cellular IoT technologies. Finally, the key open propositions of emerging technologies adapted to power wireless private network control services were analyzed, and potential research countermeasures were explored.
