5G Wireless Networks Bring Improved Operations, Security, and Performance to Aging Electrical Power Substations ENABLE POWER SUBSTATION EFFICIENCY WITH 5G TECHNOLOGY THE CHALLENGE For years, electric power systems around the world have relied on a hub-and-spoke model with large-scale generators at the center, distributing to millions of end users. At the edge of the grid, many existing power substations are operating with equipment that is more than 40 years old on average, and in some cases may have been designed and installed before World War II. These large, complex systems have improved tremendously thanks to advances in protection and control system technology, but the evolution toward renewable energy sources calls for a more adaptable, resilient model that can contend with dramatic fluctuations in electricity supply and demand in real time. How can utility engineers modernize communication and control technologies at the substation level while simultaneously improving efficiency and resiliency? THE APPROACH The industry is increasingly recognizing the benefits of digital substations, particu- larly when linked with 5G communication networks. A slate of rapidly evolving digi- tal technologies is transforming the energy sector, and telecommunications service providers that offer 5G cellular communications networks are supporting this shift. These advances unlock opportunities for efficient energy distribution, new business services, actionable data analytics, and the ultra-low latency response times that are essential to real-time operations across regional power distribution systems. Traditional copper-run electric substations are saddled with obsolete control equip- ment that boosts maintenance expenses and makes it difficult to assess the health and safety status of the equipment. Grid operators are often tasked with physically visiting the substations to detect issues and identify problems. Digital technologies and high-speed communications using 5G can improve the reliability of the grid, enhance worker safety, and minimize interruptions in power. Replacing copper signal wires with fiber-optic and 5G connectivity enables auto- mated and on-demand operations through Internet of Things (IoT), virtualization, ENERGY SECTOR CHALLENGES • To keep pace with the rapid evolution of communication and control technologies, decades-old electric power substations are overdue for a digital upgrade to boost resiliency and efficiency.
