Instructors: Robert Uluski and Stuart Borlase, ESTA International Course Syllabus: For detail information on the course click here. For several decades, electric distribution utilities have been able to achieve significant reliability improvements by quickly isolating faulted feeder sections and restoring power to healthy sections using FLISR on their distribution feeders. The growing penetration of DERs presents new challenges, such as load masking and incorrect fault location due to DER fault current contributions, that may impact the performance of these legacy systems. DER presence also provides opportunities for improved FLISR performance such as freeing capacity to permit load transfers on heavily loaded feeders and supporting islanded microgrids on isolated feeders that lack backup sources. The proposed tutorial will provide basic information on how FLISR works, equipment requirements, reliability improvement benefits obtained, and strategies for addressing the new challenges posed by DER presences and opportunities to leverage DERs for optimal performance. Objectives: At the conclusion of this tutorial students will be familiar with: FLISR operation and benefits Equipment requirements, including medium voltage switches, communication network requirements, and computer hardware and software needed to implement FLISR FLISR design characteristics such as the types of switches to use and optimal quantity of switches to install FLISR switch placement for optimal performance Potential adverse impacts of DERs, and opportunities to leverage DERs to optimize FLISR performance Business case for FLISR deployment.

Instructors: Douglas Houseman, 1898 & Co – Burns & McDonnell This half-day tutorial will address the issues with transformers, the impacts of fleet charging on the grid (e.g., trucks, rental vehicles, buses, taxies, and city vehicles, etc.), and what to think about in terms of grid upgrades and sequencing. The tutorial will draw from several examples and the lessons learned from those examples. Finally, it will take a quick look at how society changes if we shift around activities to make maximum use of solar in transportation. Objective: Understanding of: Fleets and fleet charging of electric vehicles Fleet statistics and in transit use of charging Typical locations of fleet facilities and their grid infrastructure Typical daily schedule and impacts – including sample quick calculations. Impacts on grid planning from the DOE NOPR No regrets grid planning standards and planning actions Impacts on society of maximizing solar use for fleet and EV charging.

Instructor: Avinash Kumar, Virginia Tech Renewable Energy Sources (RESs) are increasingly being implemented in the distribution system and the grid-edge to speed-up decarbonization and mitigate global warming. Conventional synchronous generator (SG) based systems are being replaced with mixed generation sources and resources such as solar photovoltaic (SPV) and wind energy conversion systems (WECS) at such a rate that a grid-edge without the conventional bulk grid is foreseeable in the next few decades. The increasing prevalence of RES and the integration of communication-supported Inverter-Based Resources (IBRs) is creating new stability, protection, and control issues to arise in addition to becoming a considerable threat surface on cyber-physical systems of microgrids networks and the grid- edge. Fast and advanced monitoring technologies are therefore needed for efficient and reliable operation of distribution grids as well as for microgrids they host. This tutorial will provide a comprehensive review of the emerging concepts, devices, and analytical methods for the monitoring of distribution grids under high renewable energy penetration. Specifically, the following aspects will be covered. Review of detailed architecture and functionalities of distribution system monitoring and the role of the distribution system operator. Review of measurement devices for distribution system monitoring including the state-of-the-art measurement devices, such as PMU, MU, DDR, smart meter, and smart inverter sensors. The principle and role of phase-locked loops will also be introduced. Review of centralized state monitoring of distribution grid as well as physics-based and data-driven estimation methods for grid-wise states and model parameters u sing various types of measurements. Introduction of the role and methodology of dynamic state and parameter estimation for online monitoring of internal operating conditions of Inverter-interfaced Distributed Generation (IIDGs) and their controllers. Introduction to measurement-based inertia estimation and emulation techniques for various types of IIDGs. Review of concepts and methodologies for islanding detection and identification. The applications of islanding information on sustainable island formation and generation-load balancing will be discussed. Review of emerging cyber-physical security monitoring and anomaly detection techniques used in the detection, classification, and localization of physical faults and cyber-attacks in distribution grids and IIDGs.
