SPEAKERS Michael Mazzola, PhD University of North Carolina at Charlotte Duke Energy Distinguished Professor Director, Energy Production and Infrastructure Center (EPIC) A Conversation about Grid Modernization and Resilience in North Carolina Abstract In this presentation, two trends driving new realities on the electric grid in North Carolina are described that in many ways reflect the larger change occurring on the North American electric grid. The first trend is the closing of central generation assets, especially coal-fired stations, and the resulting changes to grid power flows. The second trend is the emerging field of microgrids and their deployment in communities that may not have enjoyed the same high reliability that most electricity customers enjoy. The presentation finishes with some recommendations for staying ahead of these trends and countering with responses that bolster grid resiliency.

Biography Dr. Michael S. Mazzola received his PhD from Old Dominion University in 1990. In July of 2017 he was appointed executive director of the Energy Production and Infrastructure Center (EPIC) at UNC Charlotte and the Duke Energy Distinguished Chair in Power Engineering Systems. Prior

Neal Clements, PhD and Marc Aiello – Siemens Industry R&D Specialist Engineers Advances in Motor Drive Technology at Siemens, New Kensington: High Powered AC Drives Abstract M2C Development In 1994, Pete Hammond of Robicon introduced a new concept in Medium Voltage Drive technology based on what would be called Cascaded H Bridge (CCH). Siemens would later introduce this as the GH180 product family. This technology would ultimately be copied worldwide as the most widely used and accepted MV Drive topology.

The presentation will discuss the various protection functions and how they were modified to better perform in the variable frequency environment. The fault detection capability of a Perfect Harmony drive with the advanced motor protection functions will be compared with an open neutral differential protection (6 current sensor) approach.

Biography Neal D. Clements, PhD, is a graduate of the University of Toledo (BS), the University of Cincinnati (MS), and the University of Wisconsin (MS and PhD).

Ten years later, in 2003, Rainer Marquardt of Siemens and the University of Munich would introduce a bridge-based version of modular cells for High-Voltage DC applications, which would be called Modular Multilevel Converter (M2C). Siemens would later introduce this for Large Drive Applications as the GH150 product family. This technology is just beginning to penetrate the Large Drives arena.

Subhashish Bhattacharya, PhD – North Carolina State University Duke Energy Distinguished Professor NSF FREEDM Center Core Founder

With the emergence of upstream natural gas production, GH150 is gaining much interest due to its unique features over traditional voltage source bridge and multi-level topologies for high power applications.

High Power, Medium Voltage Power Converters and Applications – Opportunities and Challenges Offered by HV SiC Power Devices

With the expected boom in electro-mechanical renewable energy within the next 10-20 years, such as wind and tidal, many consider M2C to be well aligned as a key component for bulk energy harvesting and control of power to the AC and upcoming DC grid of the future.

Abstract The opportunities for HV SiC devices for MV and high power converters and utility applications and the challenges to apply HV SiC devices successfully will be presented in-depth for SiC 1200V to 1700V MOSFETs, and SiC 10 kV - 15 kV MOSFETs, JBS diodes, and 15 kV SiC IGBTs. The potential and challenges of the SiC 10-15 kV devices to enable MV power conversion systems, including MV motor drives, FACTS and MVDC grids will be explored with demonstrated application examples of SST, MV SiC power converters for grid tied solar applications, MV motor drives, and MV DC grids. Magnetics for High Power Converters with the latest advances in magnetic material qualification and characterization will be discussed.

Advanced Motor Protection Development Motor drives are often employed with an output motor protection relay. The protection relay provides various protection functions in accordance with IEEE std C37.2. Updated software functions have been developed and added to the drive to provide equivalent protection. The new protection functions have been adapted to operate in the variable frequency environment of the Siemens Perfect Harmony motor drive.

The isolated output of the drive affects the strategy for protection as well as the variable operating frequency.

Arash Khoshkbar-Sadigh, PhD ­– Penn State University Assistant Professor, Department of Electrical & Computer Engineering Dual Flying Capacitor Multilevel Inverter Abstract Nowadays, multilevel inverters are considered as the most cost-effective solutions and the state-of-the art power conversion systems in the medium-voltage and high-power applications. These converters are particularly designed to be employed in energy and power conversion areas requiring high efficiency at higher switching frequencies, high power demand, and augmented power quality.

First, general advantages of multilevel inverter in comparison with twolevel inverter will be discussed. Afterwards, some of the challenges in existing active neutral point clamp (ANPC) inverter will be addressed.

Then, a new configuration of flying capacitor-based multilevel inverter, called dual flying capacitor (DFC) multilevel inverter, will be presented

to alleviate existing challenges in conventional ANPC inverter. The main advantages of the proposed inverter are natural soft switching of line frequency switches, elimination of the transient voltage imbalance between switches connected in series, and better loss distribution between switches. Simulation results and experimental verification of the five-level DFC-ANPC inverter will be presented to validate the performance of the converter as well as the applied modulation technique.

Masoud Barati, PhD – University of Pittsburgh Assistant Professor, Swanson School of Engineering A Suite of Joint Real-time Fault Localization and Optimal Remote Fault Indicator Placement in Power Distribution – Feeders through Deep Convolutional Neural Networks Abstract Different classical fault types, fast re-closures, confused faults like high impedance faults, and unreachable feeders (ungrounded cables) in distribution grids, as well as complicated transient states after a fault event, make real-time fault location in distribution feeder challenging.

The state-of-the-art fault localization techniques rely on simplistic assumptions, such as static loads, or require much higher sampling rates or total measurement availability with more focus on the bulk power system. This talk proposes a distribution faulted feeder localization method based on a Deep Convolutional Neural Network (ConvNet) classifier using node voltages. Unlike prior data-driven methods, the proposed classifier is based on features with physical interpretations that improve the robustness of the fault location performance. The efficiency of our ConvNet based localization tool is demonstrably superior to other conventional classifiers in the literature. To further improve the fault location performance, a joint Remote Fault Indicator (RFI) placement strategy is proposed and validated against other methods. A significant aspect of our methodology is that under very low observability, the algorithm is still able to localize the faulted line to a small neighborhood with high probability. The performance of our scheme is validated through simulations of faults of various types in the IEEE Distribution Test Feeders 37-bus Feeder and 123- bus Feeder under varying uncertain conditions, system observability, and measurement attribute.

Elizabeth Cook – Duquesne Light Company Senior Manager, System Planning Embed Public and Private Clouds into Machine Learning Algorithms for Reconstructing Grid-Edge Topologies for Renewable Integration Abstract While bringing benefits, ongoing deployment of Distributed Energy Resources (DERs) causes significant opportunities to the electric utility industry, especially in the distribution grid. This calls for closer monitoring to be able to operate, plan, and maintain the distribution grid, where an accurate and real-time topology identification is the basis. Past methods are either based on maps or ideal assumption of

an isolated sub network. To solve these problems and other issues on limited measurements and un-scalable algorithms, this presentation proposes hierarchical solutions to combine theoretic analysis, practical challenges, and Geographical Information System (GIS) information to resolve topology reconstruction problems. Preliminary results show highly accurate reconstruction accuracy and fast speed, opening the door for monitoring and control in the secondary distribution grids.

Amy Babay, PhD – University of Pittsburgh Assistant Professor, School of Computing and Information (SCI) Spire: Intrusion-Tolerant SCADA for the Power Grid Abstract As SCADA systems move to use IP networks to take advantage of their cost benefits and implement smart-grid capabilities, the traditional assumptions that these systems are air-gapped and inaccessible to outside attackers no longer hold. While modern fault-tolerant SCADA architectures provide sufficient resilience to overcome benign failures, they are not adequate to cope with the hostile environments that SCADA systems are now being exposed to.

To address this problem, we introduce Spire, the first SCADA system for the power grid that is resilient to both system-level compromises, in which an attacker gains control of part of the system, and sophisticated network-level attacks and compromises. In this talk, I will describe our experience developing the Spire system and the intrusion-tolerance techniques that it uses to maintain correct operation and guaranteed performance even while subject to a successful attack. I will also describe lessons learned from two deployment experiences with the system: a red team experiment conducted at Pacific Northwest National Lab in 2017, and a test deployment with the Hawaiian Electric Company in 2018.
