How Does 5G Enhance Microgrid Security and Resilience?

In the emergent landscape of modern electricity distribution, the question of how to seamlessly integrate cutting-edge communication technologies with energy systems is of paramount interest. The National Renewable Energy Laboratory (NREL), with funding from the U.S. Department of Defense’s FutureG program, has been scrutinizing the dynamics of 5G technology and its impact on power systems. This is most pertinent for microgrids, which are smaller, localized versions of the larger power grids and are increasingly reliant on sophisticated communication systems to manage their operations effectively—especially in critical scenarios such as military bases.

Revolutionizing Microgrid Performance

NREL’s groundbreaking research delves into the implementation of 5G within a replicated military base microgrid, presenting a unique case study in the resilience and manageability of power distribution networks. The essence of this experimentation lies in the juxtaposition of a microgrid with a 5G communications network. This allowed for uninterrupted interaction between the two technologies under conditions that included grid failures and cyberattacks, providing a real-world sense of their interoperability and robustness.

While assessing the features that 5G could contribute, key findings emerged. The technology’s low latency and advanced capabilities, such as edge computing, network traffic prioritization, and private slicing, were demonstrated to enhance the performance of microgrids materially. However, this leap in efficiency was not without its caveats. While 5G reduced latency substantially, it failed to reach the ultralow benchmark essential for the seamless coordination of power systems during restoration periods. This highlights a gap where further technological advances are imperative.
