The Role of Smart Grids in Modern Power Systems
Smart grids mark a significant evolution in how electricity is distributed and managed. By integrating advanced information technology, communication tools, and data analytics, these systems enable real-time monitoring and optimization of energy usage. This boosts efficiency and strengthens grid resilience—especially when it comes to incorporating renewable energy sources.
The International Energy Agency (IEA) estimates that digitalization within smart grids could reduce renewable energy curtailment by over 25% by 2030, resulting in more efficient and cost-effective energy systems.
Recent advancements in smart grid technology, such as advanced monitoring sensors and artificial intelligence, further propel this transformation, leading to improved grid reliability, enhanced energy efficiency, and greater integration of renewable energy sources.1,2
Enhanced Grid Monitoring with Thermal and Visual Sensors
A key development in smart grid technology is the integration of thermal and visual sensors into grid infrastructure, enhancing monitoring and control of critical systems. These sensors facilitate real-time fault detection, improving operational efficiency.
Recently, Noralarm, a Norwegian security company, installed these sensors in Lyse Energy's electrical substation in Stavanger, Norway. These sensors enable utilities to detect anomalies that signal potential failures, leading to a 20% reduction in breakdowns and annual savings exceeding $9 million.

These sensors enhance security at electrical substations, reducing risks associated with vandalism and wear-related failures.
This proactive monitoring enables utilities to shift from reactive to predictive maintenance strategies, significantly reducing downtime and enhancing overall grid performance.3
AI and Machine Learning in Smart Grid Technologies
Artificial intelligence (AI) and machine learning play a significant role in advancing smart grid technologies.
Real-time energy consumption forecasting
A recent study published in Frontiers in Energy Research combined temporal convolutional network (TCN), bidirectional gated recurrent unit (BiGRU), and attention mechanisms to enhance energy demand prediction and management in large-scale buildings and sports venues.
This model accurately forecasts energy consumption patterns for lighting, cooling, and heating, allowing real-time optimization, cost reduction, and energy conservation. In addition, the attention mechanism enables more precise energy allocation based on regional and temporal needs, ensuring efficient use during peak times and reduced wastage during off-peak periods.
This model improves energy efficiency and reduces energy wastage, contributing to more sustainable energy management strategies.4
AI-powered self-healing grids
Another notable development is the AI-powered self-healing grids designed by University of Texas researchers. These grids autonomously detect and repair electrical grid issues, significantly reducing energy loss during outages.
The technology employs graph reinforcement learning to model the grid network, optimizing power flow and minimizing disruptions during outages. In multiple network configuration tests, the AI system demonstrated real-time fault detection and repair with response times in milliseconds, a substantial improvement over conventional systems that typically take minutes to hours to respond.
As this technology matures, it has the potential to transform grid management, leading to more robust, efficient, and reliable power networks.5
Gridspertise's Medium Voltage Grid Automation Module
Electrical grids over 40 years old often struggle to meet modern energy demands, and traditional manual fault detection results in costly, prolonged outages.
Gridspertise recently introduced a new universal module for medium-voltage grid automation that enhances fault detection and grid reliability. The module can integrate with any supervisory control and data acquisition (SCADA) system, upgrading legacy capabilities with smart fault selection and advanced fault location, isolation, and service restoration (FLISR) and achieving recovery times of less than a second.
This comprehensive approach empowers DSOs to proactively manage faults, optimize resources, and enhance customer satisfaction through improved control and reduced response times.6
Cybersecurity in Smart Grids
Cybersecurity has become a critical concern as smart grids become more interconnected and reliant on digital systems. A new smart grid laboratory at Thales' UK Cyber Resilience Lab in Ebbw Vale, South Wales, developed in collaboration with Schweitzer Engineering Laboratories (SEL), aims to address this need.
This facility will provide tailored cybersecurity solutions for the UK energy market, including training and workshops for utilities focused on system hardening, vulnerability assessments, and intrusion detection. In addition, it will support research on secure-by-design solutions and facilitate test-and-learn demonstrations for electrical utilities.
Facilities like this are vital for safeguarding the future of energy supplies, ensuring that security vulnerabilities do not compromise the benefits of smart grid technologies.7
Global Smart Grid Projects
Several large-scale smart grid projects are underway, showcasing the global commitment to grid modernization.
A prominent example is Canada's Sault Smart Grid, the country's first community-wide smart grid. This $34 million project is transforming Sault Ste. Marie's energy distribution system by enhancing reliability and reducing greenhouse gas emissions. It integrates various smart grid technologies, such as distributed automation, voltage management, and real-time operational awareness, to facilitate the seamless adoption of distributed energy resources (DERs), including solar panels and electric vehicles.
The project's impact is already evident, with a 2.7% reduction in energy consumption, resulting in $2.3 million in annual savings. Furthermore, it has reduced carbon dioxide emissions by over 2804 tons annually, demonstrating the environmental benefits of smart grid technologies.8,9
Conclusion
These technological developments, from grid automation modules to AI-powered self-healing grids, reflect the growing emphasis on resilience, efficiency, and sustainability in the energy sector.
As the world transitions toward a cleaner and more efficient energy future, these smart grid technologies will be essential for adapting energy systems to climate change and rising demand.
