Enhancing Grid Resilience through DMR Trunking Communication Systems

As the frequency of natural disasters and cyberattacks increases, ensuring the reliability and resilience of power grid communication systems has become a critical concern. This paper explores the integration of Digital Mobile Radio (DMR) trunking communication systems into Supervisory Control and Data Acquisition (SCADA) systems to improve grid resilience during emergencies. The methodology, based on the work of Md. Shahiduzzaman Rabbi, presents an innovative approach for enhancing the reliability and performance of grid communication by incorporating DMR as a fallback mechanism. Through simulations based on a Texas microgrid testbed, this study demonstrates the effectiveness of DMR in reducing grid restoration times, improving command delivery success rates, and ensuring secure and reliable communication during network disruptions. The results highlight the potential of DMR trunking as a cost-effective, scalable solution for enhancing grid resilience in smart grid environments.
