Connecting the Grid: How 5G Enhances Electrical Substation Operations

Challenges

Electric substations play a crucial role in the power distribution infrastructure. Energy suppliers operate across various fields and locations, frequently managing assets in remote areas lacking onsite personnel. Improved security and monitoring at the edge are critical in the energy and utilities sector for multiple reasons, including facilitating real-time monitoring, reduced latency, and better security measures. However, they face several challenges that can impact their efficiency and reliability.

To address these challenges and implement 5G Network in an Electrical Substation Operations, energy suppliers could leverage edge computing technologies that enhance real-time surveillance, reduce latency, and improve security. These advancements are critical for maintaining the reliability and efficiency of energy
management systems.

COVERATE AND CONNECTIVITY

Due to geographical distribution, often in remote areas , electric substations face the
challenge of maintaining robust connectivity. This is essential for facilitating communication and real-time data transmission across the power distribution infrastructure, which is critical for monitoring and control of the electrical grid maintaining reliability and efficiency of the power distribution network.

OPPERATIONAL INEFFICIENCY AND AGEING INFRASTRUCTURE

Traditional electric substations, often hampered by outdated copper-based control systems that are prone to failures and increase maintenance costs. In addition outdated infrastructure poses challenges in monitoring the health and safety of equipment. Typically, grid operators must conduct physical inspections to identify and resolve issues.

CENTRAL VISIBILITY & MANAGEMENT

Due to the remote & dispersed nature of substation, it is difficult for providers to have a
centralised view and control over operations on a per-site basis.This may lead to issues such as lack of real-time data, inconsistent operations, poor visibility of complex asset management and resource-intensive operations.

PRIVACY & SECURITY

The increasing connectivity of substations exposes them to cyber threats that can disrupt
operations. Data privacy is crucial for security, compliance, and efficient collaboration among substations within a network. As the substations are interconnected within a larger network, central management becomes necessary to maintain visibility and control across the networks.

SCALABILITY

Cloud-based solutions may face scalability limitations when dealing with thousands of
distributed electric substations.

OPERATIONAL COSTS

Transmitting large amounts of data to the cloud can be costly in terms of bandwidth and
resources. Additionally, the cloud is not always the best option for applications requiring low latency.

RESPONSE TIME

Decisions in substations must be made quickly to prevent failures or interruptions in the power supply. Latency in data transmission negatively affects swift decisions on operational management, lack of real-time data increases response time which impacts the reliability of the grid and potential safety hazards.

The implementation of 5G Private Network (5G PN) in an electrical substation is complex and requires specific tools to manage and automate the various infrastructures, network functions and applications. To make a viable solution, a robust and easy-to-use private cloud-native core is paired with a flexible and scalable solution that can orchestrate everything from a single site all the way to a widely distributed network, preferably from a single interface.
This document illustrates how to implement a 5G PN in an electrical substation and enable the following use cases: video analytics and drone inspection with Raemis™, Druid Software’s 5G core, & NearbyOne’s automation platform

Druid’s RAEMIS™ 5G core network platform

Raemis™ is a set of cellular software assets optimised for business critical use cases. The platform harnesses 5G, 4G, 3G, 2G and Wifi radios from any vendor to implement standalone cellular core network solutions. It also integrates with mobile network operators using standard interfaces giving access to all of the radio resources of these operators. The Raemis™ platform adheres to 3GPP standards and stands out for its flexibility, slicing capabilities, interoperability, and simplified deployment and testing options, making it a compelling choice for private network deployments. Druid’s technology enables organisations to deploy private networks on-premises, in the cloud, or at the edge with enhanced connectivity, robust security, exceptional reliability and cost-efficiency.

The automation platform, NearbyOne

Will deploy Druid’s core in different environments, from any hyperscaler infrastructure to private clouds and onpremises, ensuring a fully streamlined Day-0 deployment and automated lifecycle management, saving up to 90% of operation time and minimising operation costs. In addition, NearbyOne orchestrates Druid’s core slicing allowing multiple network slices to be created on top of a common physical infrastructure. Each slice can be allocated based on the specific needs of the applications, use case, or customer. Furthemore, thanks to the automation, services on the MPN can be exposed, or not, to specific slices automatically. That is, when a new slice is added, the orchestrator will ensure to expose all those services bound to all slices plus those bound to the new slice. Finally, Druid’s core, UPF, and slices can all be managed from the same dashboard used to manage services and infrastructure; providing a single-pane of glass to manage the entire MPN.

Value proposition

R The joint solution between Druid Software and NearbyOne offers the most complete, flexible, economic and reliable 5G private connectivity, giving access to edge computing application management in minutes.

R By deploying Druid’s 5G Core with NearbyOne orchestration platform, enterprises can significantly reduce costs through automation which helps to complete tasks in minutes significantly reducing required resources. This partnership gives end-users numerous advantages including Druid’s streamlined Day-0 deployment and NearbyOne’s automated lifecycle management. Together these features result in up to a 90% reduction in operation time ensuring swift and automated deployment and management of the 5G Core.

R Due to the nature of the solution, operators can also pivot to provide value-added services from all locations leveraging the 5G private network to communities located around all the distributed sites. These can be for example fixed wireless access services (last mile solutions) integration of smart metering solutions, backhauling services for local authorities, and many other services, allowing operators to generate extra revenue from their existing infrastructure.
