“…Several industry and open-source software platforms exist for capturing and visualizing PMU and SCADA data streams. Real-Time Dynamics Monitoring System [7], or RTDMS, is a platform for realtime grid monitoring that includes many "familiar" views that are standard to domain operators: geographic displays overlaid with the grid topology to show network state and connectivity, line charts for raw PMU data streams, and odometer-inspired radial dials for phase angle separation, voltage sensitivity, oscillation, and grid stress monitoring. Other wide-area monitoring and control systems include Babazadeh et al [3] and Cozby et al [9].…”

“…Event Tracking is Faster with a Tailored View. The experts agreed that the dendrogram panel streamlined PMU selection and analysis for event identification and epicentric propagation tracing, particularly when compared to non-epicentric monitoring interfaces [7], which mimic topological data display for the power grid's network of PMUs. In part, this reflects how custom-designed visualizations can better support data-driven power grid analytic needs, instead of relying on "traditional" techniques, such as the node-link diagrams (which are commonly used in control rooms) that provide top-down perspectives of the grid.…”

The electrical power grid is a critical infrastructure, with disruptions in transmission having severe repercussions on daily activities, across multiple sectors. To identify, prevent, and mitigate such events, power grids are being refurbished as 'smart' systems that include the widespread deployment of GPS-enabled phasor measurement units (PMUs). PMUs provide fast, precise, and time-synchronized measurements of voltage and current, enabling real-time wide-area monitoring and control. However, the potential benefits of PMUs, for analyzing grid events like abnormal power oscillations and load fluctuations, are hindered by the fact that these sensors produce large, concurrent volumes of noisy data. In this paper, we describe working with power grid engineers to investigate how this problem can be addressed from a visual analytics perspective. As a result, we have developed PMU Tracker, an event localization tool that supports power grid operators in visually analyzing and identifying power grid events and tracking their propagation through the power grid's network. As a part of the PMU Tracker interface, we develop a novel visualization technique which we term an epicentric cluster dendrogram, which allows operators to analyze the effects of an event as it propagates outwards from a source location. We robustly validate PMU Tracker with: (1) a usage scenario demonstrating how PMU Tracker can be used to analyze anomalous grid events, and (2) case studies with power grid operators using a real-world interconnection dataset. Our results indicate that PMU Tracker effectively supports the analysis of power grid events; we also demonstrate and discuss how PMU Tracker's visual analytics approach can be generalized to other domains composed of time-varying networks with epicentric event characteristics.

“…Typical power system applications [36][37][38][39] These applications run in parallel at the PMU data speed, which helps improve operators' visibility to system dynamics and events, and assists operators to take actions to improve system reliability. For instance, the Automated Event Analyzer application provides grid operators with information immediately following a system event.…”

State estimation is a critical functionality of energy management system (EMS) to provide power system states in real-time operations. However, problems such as failure to converge, prone to failure during contingencies, and biased estimates while system is under stressed condition occur so that state estimation results may not be reliable. The unreliable results further impact downstream network and market applications, such as contingency analysis, voltage stability analysis, transient stability analysis, system alarming, and unit commitment. Thus, operators may lose the awareness of system condition in EMS. This paper proposes a fully independent and one-of-a-kind system by integrating linear state estimator into situational awareness applications based on real-time synchrophasor data. With guaranteed and accurate state estimation solution and advanced real-time data analytic and monitoring functionalities, the system is capable of assisting operators to assess and diagnose current system conditions for proactive and necessary corrective actions. The architecture, building components, and implementation of the proposed system are explored in detail. Two case studies with simulated data from the subsystems of Electric Reliability Council of Texas (ERCOT) and Los Angeles Department of Water and Power (LADWP) are presented. The test results show the effectiveness and reliability of the system, and its value for realtime power system operations.
