Next-Generation of Grid Awareness: Machine Learning and PMU Analytics for Secure Power System Operation
This panel presents four complementary perspectives on how PMUs, WAMS, and machine learning techniques are moving towards a new generation of grid awareness. The first topic addresses the short-term voltage instability phenomena, a problem of IBR-dominated weak grids. Here, a novel Maximum Lyapunov Exponent-based algorithm for the detection of this phenomena will be presented. Then, event detection and frequency-dynamics monitoring using real PMU data from the Brazilian Interconnected Power System will be presented. A two-level methodology combining wavelet-based spectral analysis and deep learning enables robust multi-label classification of real disturbances, while a complementary framework quantifies how increasing IBR penetration is degrading both global and regional frequency behaviour. Moreover, a self-healing transmission grid concept for real-time dynamic vulnerability assessment (DVA) leveraging PMU data and long-short term memory neural networks will be discussed. This approach identifies evolving symptoms of system stress, including transient, oscillatory, voltage, and frequency instability, supporting timely activation of adaptive corrective controls and system integrity protection schemes. Finally, a data-driven transient stability assessment (TSA) designed for fast operation in low-inertia grids will be described. The approach is based in PMU measurements and uses the Maximum Lyapunov Exponent (MLE) and machine learning models to provide rapid model-free stability indicators capable of triggering corrective actions to prevent loss of synchronism.

Data-Driven Transient Stability Assessment and Control in Modern Power Systems
The increasing complexity of power systems, driven by renewable integration and reduced inertia, demands fast and reliable methods for transient stability assessment (TSA). Traditional model-based approaches are computationally intensive and unsuitable for real-time operation. Maintaining accurate models and keeping them updated is increasingly challenging in modern grids. This talk presents data-driven TSA techniques that leverage phasor measurement unit (PMU) data and advanced algorithms such as Maximum Lyapunov Exponent (MLE) and machine learning models. We discuss how MLE-based nearest neighbor algorithms enable fast, model-free TSA, and compare their performance with deep learning approaches like Convolutional Neural Networks (CNN). Furthermore, we explore how these assessments can trigger corrective control actions such as braking resistors, fast valving, and reactive power support to prevent loss of synchronism. Case studies on Nordic and IEEE benchmark systems demonstrate that data-driven TSA combined with corrective control significantly enhances system resilience and operational security.

Real-Time AI/ML Application for Data-Driven Power Grid Analytics
The increasing complexity of the modern power grid, driven by inverter-based resources, distributed energy systems, and tighter operational margins, demands real-time, data-driven analytics beyond traditional model-centric approaches. This work presents future research needs for real-time AI/ML application in synchronized grid data analytics that enables fast anomaly detection, event versus bad-data classification, event type identification, spatial localization, and operator decision support under strict latency constraints. The proposed approach leverages streaming machine learning models operating on synchronized measurements from PMUs, µPMUs, and high-speed sensors. Unsupervised and physics-informed learning techniques continuously learn normal system behavior and detect deviations in real time. Advanced classifiers should distinguish grid events, such as faults, asset failure, oscillations, and inverter interactions given measurement errors, communication and timing issues. Spatiotemporal and graph-based learning models can exploit network topology to classify and localize events even with incomplete observability. To meet scalability and latency requirements, edge vs centralized computing need to be analyzed for fast detection and dynamically adjust data reporting rates, enabling event-driven data delivery from affected regions. This talk will also highlight critical future needs in latency-aware AI, physics-informed and trustworthy ML, scalable edge intelligence, and the integration of real-time analytics with operator-centric decision-making, to enable resilient grid operations.

Synchronized measurement technology and its application in disturbance identification for power systems with high penetration of renewable energy
To protect the environment, countries around the world are integrating renewable energy sources into their power grids. However, this rapid growth in renewable energy has brought new safety and stability challenges to power systems, such as transformer failures, deteriorating power quality, and even large-scale power outages caused by cascading fault. Therefore, there is an urgent need for real-time synchronized monitoring technologies to support the safe and stable operation of power systems with high penetration of renewable energy. First, a high-precision dynamic phasor measurement method based on a complex band-pass filter has been proposed, which pioneers the extension of the measurement perspective from the time domain to the frequency domain. This method reduces the amplitude measurement error from 1% to 0.05%, while expanding the measurement frequency band from 45-55 Hz to 20-80 Hz. And a short-time window harmonic measurement method based on spectral line interpolation fitting has been proposed, which, for the first time, achieves a measurement bandwidth covering from 0 Hz-20 Hz and 80 Hz-2500 Hz. This method reduces the amplitude measurement error from 5% to 0.5%, filling a technological gap in the field. Then a transient waveform dictionary generation method based on clustering pruning optimization has been proposed to effectively characterize disturbance characteristics, realizing a root mean square error of less than 1% for disturbance waveforms and achieve a compression ratio of 5.33-8.33. After that, a method for generating time-frequency maps through second-order motif difference field has been proposed to achieve the image-based encoding and extraction of high-dimensional features of disturbance signals. The loss function is optimized based on metric learning, expanding the decision boundary and achieving identification accuracy from 84% to 96%.

Future Research Needs for Dynamic Operational Security
This presentation will discuss the research needs for securing operational security and give examples from the Nordic power system which is undergoing rapid transformation.

This presentation will highlight opportunities for research and innovation in dynamic stability assessment, real-time operational limits, and cross-border coordination, ensuring that frequency control, balancing, and transmission capacity remain reliable cornerstones of a sustainable and resilient power system.

A Time-Synchronized Adaptive Power Flow Control of Embedded HVDC links in the Brazilian Interconnected Power System
Brazil has historically relied on hydropower to supply over 90% of its annual electricity demand. In recent years, however, this dominance has declined as wind and solar generation have grown significantly. Having a continental size, the Brazilian Interconnected Power System (BIPS) relies heavily on a large network of AC transmission lines, plus 6 HVDC links with a DC transmission capacity of 20 GW in total. The growth of renewable energy with its intermittent characteristics, paired with market-based generation dispatch, has put new demands on the control systems of embedded HVDC links. To mitigate loop power flows in the hybrid AC–DC network, the embedded HVDC link employs a time-synchronized angle difference control scheme between its rectifier and inverter terminals. The study presents the outcomes of this prospective control approach, which adapts DC power flow setpoints in real time according to variations in solar and wind generation dispatch.

Applications of Synchronized Measurements and Analytics in Latin American Power Systems
Wide area monitoring systems (WAMS) are now an important part of the operations in the power systems of Latin America. Some electrical systems in the region form interconnections, such as the Electrical Interconnection System for Central American Countries (SIEPAC), which can be also synchronized with the electrical power system in Mexico. In the case of South America, the possibility of interconnection between electrical systems is even more complex due to geographical challenges and the distances between the different systems. However, there are interconnections, such as Ecuador and Colombia, as well as interconnections between neighboring countries in the Southern Cone. Thanks to synchrophasor measurements, it is possible to monitor the interconnections and disconnect the systems to prevent the propagation of oscillations. The operators in Latin America have been developing different type of applications and in this panel, the experts will share their insights about the experiences in their corresponding region.

Requirements, Testing, and Validation of Large Scale WAMPAC Systems
Modern power systems worldwide are undergoing significant transformations driven by increased interconnection, higher penetration of renewable energy, and growing operational complexity. One critical concern is the potential for non-credible contingencies, such as the simultaneous loss of multiple transmission elements, which can lead to transient instability, system separation, and widespread supply disruptions. To mitigate these risks, system operators increasingly rely on advanced Wide Area Monitoring, Protection, and Control (WAMPAC) systems. These systems leverage synchronized measurements, real-time communication, and coordinated control strategies to enhance situational awareness and enable rapid, automated responses to disturbances. This panel explores the key stages and design considerations involved in deploying large-scale WAMPAC systems for modern power networks, highlighting challenges related to system architecture, communication infrastructure, control strategies, and coordination with existing protection schemes. The discussion also emphasizes the importance of emergency control functions in maintaining stability and minimizing disruption under extreme operating conditions, providing insights applicable to power systems globally.

Testing and commissioning the South Australia Interconnector Trip Remedial Action Scheme
The core components of the South Australia Interconnector Trip Remedial Action Scheme (SAIT RAS) include: Event-Driven Component (EDC): topology-based scheme that monitors weakening or breaks of double circuit transmission corridors. Response-Driven Component (RDC): synchrophasor-based scheme designed to detect complex network events and to limit the need for overcompensation by the EDC. Resource Controller Component (RCC): upstream, it serves as the main interface to ElectraNet's Energy Management System (EMS) and downstream, as the issuer of trip/control signals to resources such as loads, generators and BESSs. SAIT RAS is a complex Wide Area Monitoring, Protection and Control (WAMPAC) scheme that spreads across three Australian states. Its correct operation is critical to maintain system stability not only in South Australia, but also the wider National Electricity Market (NEM). Deploying a complex control scheme of this scale requires layers of testing and significant effort to ensure all scheme components are modelled, validated and documented properly.

Utility Experiences with PMU Applications in Control Room
Over the past decade, many utilities have made significant investments in deploying synchrophasor technologies across their transmission networks. Phasor Measurement Units (PMUs) are now widely installed in substations, providing high-resolution, time-synchronized data with the potential to enhance situational awareness, dynamic monitoring, and real-time decision-making. Despite this progress, the practical use of PMU data in control room operations remains limited at many system operators. In most cases, the challenge is not the availability of data, but the absence of well-defined operational processes, visualization tools, integration with existing Energy Management Systems, and clear roles for operators to act on synchrophasor-based insights. This panel focuses on real-world utility experiences in bringing PMU applications into the control room environment. Drawing on firsthand operational knowledge, panelists will share success stories, lessons learned, and common obstacles encountered when transitioning synchrophasor data from engineering and planning use cases into daily operations. Topics will include organizational and workflow challenges, operator trust and training, application design, and strategies for aligning PMU analytics with operational needs. The discussion aims to provide practical guidance for utilities seeking to move beyond infrastructure deployment toward meaningful operational use of synchrophasor data, helping the audience understand how to overcome barriers and accelerate value realization in the control room.
