Abstract: The past decade has witnessed a growing interest in electric vehicles (EVs) from both academia and industry. Such an interest is driven by the environmental and economic advantages brought by EVs. A recent study has revealed that the annual operation cost of an EV in the U.S. is $485 on average, while it is $1,117 for a gasoline-fueled vehicle, which represents 57% reduction in annual expenses. Furthermore, recent studies have demonstrated that EVs can significantly reduce the carbon dioxide emissions as they reduce the dependence on fossil fuel. Due to the aforementioned advantages, a recent report has shown that the number of EVs on the U.S. roads has increased over the past decade from a couple of thousands in 2011 to $1.2 million vehicles in 2019. A similar trend has been also observed worldwide. To accommodate the charging demands of such EVs, charging facilities have been deployed across the parking lots at residential and commercial units and at work places. Furthermore, fast charging stations have been allocated to serve EVs traveling on the roads. To cope up with the exponential increase in the number of EVs, additional measures have been adopted including temporal and spatial coordination of EV charging and discharging requests. In order to carry out the aforementioned planning and operational goals, advanced stochastic models and optimization techniques must be employed in order to: (a) model the stochastic nature of arrival and departure of EV charging requests, (b) model regular loads and generation units in the power grid to efficiently balance the total supply and demand, (c) allocate EV charging stations in the most economic manner while accounting for spatial and temporal increase of EV charging demands, and (c) coordinate the charging requests of parked and mobile EVs in the most satisfactory manner. This tutorial will equip the researchers with theoretical background of stochastic models and optimization techniques needed for efficient integration of EVs in smart grids. These tools include: Markov processes, queue models, stochastic geometry, mixed-integer programming, heuristic optimization, and game theory. The application of these tools to design planning and operation algorithms for EV integration in smart grids will be covered. This include optimal static and dynamic allocation of charging stations, optimal design of number of chargers and waiting space in charging station, and temporal and spatial coordination of charging requests from parked and mobile EVs in gridto-vehicle (G2V), vehicle-to-grid (V2G), and vehicle-to-vehicle (V2V) scenarios. Furthermore, the tutorial will present datasets and simulators available for researchers and discuss their application scenarios.
Motivation: Over the last decade, smart grid literature focusing in the integration of EVs has evolved significantly and it is often challenging for graduate students and young researchers to develop the background needed to synthesize theory and practical execution. This is particularly the case for IEEE SmartGridComm audience as it is composed of researchers with diverse backgrounds and often not trained with power systems education and may lack necessary stochastic modelling and optimization background needed to carry out research in integration of EVs. This tutorial will put above said topics and solutions methods into perspective and present wide range of practical case studies and tools needed to address them.

Tutorial 2: Power System Machine Learning Applications: From Physics-informed Learning for Decision Support to Inference at the Edge for Control

Abstract: Electrical power networks are facing unique challenges in their operation and control. With the increasing penetration of variable & intermittent renewable energy sources and limited transmission capabilities, grid operations and control is becoming evermore complex. However, the transition into the “digital utility” is brining unprecedented opportunities to leverage measurement data with conventional analysis methods, that when combined together, can help in achieving the goals for a “green” energy transition. In this context, Artificial Intelligence and Machine Learning are emerging as a cohort of theory, methods and technologies that if applied properly to solve power system problems, may have an invaluable contributions to solve existing and future grid challenges.
This tutorial provides insights from a team of power system specialists on the development of Machine Learning-based for power system applications using both measurements and physics-informed simulation. The scope of the presentation is on how to frame to power system problems and apply ML existing methods and technologies, and not on ML itself.
The tutorial is divided in three parts. First, an overview on today’s hierarchical power system operation and control is given, identifying a few of the potential areas where ML can be be of substantial benefit to power system operations for decision making at the control center to inference at edge devices in control/protection.
Second, on-going research in the development of a “recommender system” for operator decision support will be presented. Such type of predictive application cannot rely on measurement data alone, it has to be complemented with physics-informed models and simulation. In other words, this is a case where both measurement-based and simulation-based ML analytics need to be combined. Hence, this part of the presentation makes a strong emphasis on the careful design of simulation models, algorithms for automated simulation scenario design and software pipelines for automated generation of simulation data. Many challenges were faced when building a toolchain that makes this possible. We illustrate the challenges faced to adopt not only ML methods, but the computing software environments and hardware required in ML workflows so to be able to scale for realistic use cases.
Finally, we illustrate the first results obtained using our proposed approach for classification of power system stability using both traditional data science methods and Deep Learning. Finally, on-going research in the development of “edge” applications in power systems will be presented. The use case is the detection of undesirable sub-synchronous control interactions between the power grid and wind turbines for potential use in control and protection at the “edge”, i.e at the wind-farm location, which would require a ML-based apparatus capable to provide reliable predictions in real-time. We illustrate the challenge of having a reduced measurement data set to train such detection algorithm, and how simulation helps to solve this problem. Furthermore, we illustrate the performance of the developed ML-based solution on three different hardware platforms.

Tutorial 3: Accelerating AI on the Grid: A Hands On Tutorial on PMU Data Analysis
Date: Friday, 13 November
Time: 17:50 – 18:10 UTC
Abstract: This tutorial will prepare attendees to analyze PMU (synchrophasor) data for research and practical applications. The tutorial will provide hands-on experience with state-of-the-art tools for digesting and visualizing high-frequency time series data, and for exploring novel applications.
PMU data give empirical evidence of physical phenomena that happen on time scales unobservable to conventional sensor networks. Effective use of PMU measurement data can unlock novel opportunities for using Artificial Intelligence (AI) to extract insights into the condition of the grid. Making these insights accessible to decision makers in real-time has already begun to radically change best practices in grid operations, maintenance, and planning.
This tutorial will provide attendees with the context and skills they need to leverage AI methods to begin using PMU and other high frequency data in their own work. The course will begin by teaching fundamental concepts from power systems engineering, and their relation to PMU measurement data. This talk will provide context necessary for both newcomers and domain experts to begin analyzing and interpreting PMU data. The course will go on to describe the data analytics program at Dominion, where streamlined access to PMU data has unlocked unexpected opportunities to improve decision-making processes related to grid operations, maintenance, and planning. Finally, we describe how companies that are successful at leveraging data and AI have radically changed the way they do business. We discuss examples from other sectors, such as Amazon and Google, and will share an outlook for similar transitions in the energy sector
Attendees will gain hands-on experience working with PMU data and state-of-the-art computational tools designed to facilitate the analysis and interpretation of big data. The hands-on portion of the session will use the National Infrastructure for AI on the Grid (NI4AI) powered by PingThings’ PredictiveGrid TM Platform and will provide real-time support for participants to gain API access to PMU and other data that are publicly hosted on the platform. Talks will include an interactive exercise for participants to familiarize themselves with the visualization capabilities of the platform, and to access the data on their personal computers using the Python API. Talks will include live coding demonstrations of two use cases for PMU data, to examine voltage sag events and explore the relationship between solar generation and voltage or frequency on the grid. Participants are requested to bring personal computers that they may follow along and replicate analytics on their own devices
Motivation: There is growing interest among researchers and utilities to apply AI to extract insights from PMU and other sensor data. Early successes have demonstrated that these data can enable decision-makers to take more effective and more timely actions. Many of these insights were either time-consuming or impossible to access using conventional sensor data. Work to date provides strong evidence that continued advancements in the collection and interpretation of sensor data will fundamentally change the nature of decisions that are made in grid operations and planning. Familiarity with PMU measurement data and tools that can streamline workflows for analysts will become increasingly valuable. These skills are relevant both to researchers seeking to develop new analytic algorithms, and to industry practitioners seeking to improve decision-making processes within their organizations. The tutorial will also familiarize participants with NI4AI, an ARPA-E funded project that makes high-frequency sensor data readily accessible to students, academics and professionals. The platform provides users with access to anonymized sensor data, and can facilitate selected data sharing between academic institutions or with industry partners. Users can easily and efficiently query the data through an API that supports Python, Julia, and other programming languages. Through hands-on experience, participants will be able to more effectively leverage these state-of-the-art tools for grid data analysis in their own work.
