Sharing the Ride of Power: Understanding Transactive Energy in the Ecosystem of Energy Economics |
IEEE PES |
Advocates of Transactive Energy (TE) make arguments for the integration of distributed energy resources (DERs) into a market environment from the standpoint of overall energy economics, customer choice, facilitating technology adoption, and encouraging innovation. At a very high level, this is reasonable given the rapid development and adoption of personalized transactions via the web and mobile computing in many domains and the equally rapid proliferation of DERs, at least in some geographic areas. |

Energy Storage Primer |
IEEE PES |
Energy storage continues to emerge as one of "non-conventional alternatives" to mitigate the effects of renewable variability, optimize the utilization of existing grid infrastructure, and improve resilience and reliability by providing end users with the ability to self-supply during outages. Energy storage is a flexible resource for grid operators that can deliver a range of grid services quickly and efficiently. Unfortunately, the cost of many of these services still exceeds their value, compared to conventional solutions. As energy storage technology becomes more cost-effective, a wider range of applications will become accessible. The purpose of this Primer is to provide a fundamental understanding of the roles of energy storage in the electric grid and explain why it is more complex than simply inserting a battery into a phone, requiring careful engineering design expertise.

Smart Meters and Grid Modernization: A Guide to a Successful AMI Implementation |
A Quanta Technology White Paper |
The demands on the power grid in the 21st century are rapidly changing. Many utilities are looking to grid modernization plans to meet these challenges. Grid modernization is not a series of individual technologies but a prioritization of investments that create a portfolio of technologies to meet the utility’s vision. These technologies may require integration as well as new processes and trained staff to manage them. A major component of many plans is smart meters that make up an advanced metering infrastructure (AMI) system. To be a successful component of a plan, care must be taken in the planning, process development, implementation, and integration of the AMI system to ensure the utility’s goals and vision are met.

Accidental Islanding of Distribution Systems with Multiple Distributed Generation Units of Various Technologies |
CIGRE |
The system response to accidental islanding and effect on anti-islanding detection of distribution
feeders with multiple distributed generation (DG) technologies (synchronous machine and inverterbased units) is one major utility concern associated with increasing penetration of DG. Studies have
been conducted to evaluate the performance of anti-islanding detection through use of conventional
voltage and frequency protection elements, and a non-detection zone (NDZ) defined in terms of real
and reactive power mismatch scenarios. However, this NDZ applies to only synchronous generator
DG technology, and efforts to characterize system behaviour and performance of anti-islanding
detection for systems with mixed inverter and machine units have been limited. This paper
investigates the effect of adding inverter-based DG to the system under various real and reactive
power mismatch scenarios. |

Design for Distributed Energy Resources |
IEEE |
The blackout experiences have demonstrated the vulnerability of the interconnected electric power system to grid failure caused by natural disasters and unexpected phenomena. Changes in customer needs, additional stress due to liberalized electricity markets, and a high degree of dependency of today's society on sophisticated technological services also intensify the burden on traditional electric systems and demand for a more reliable and resilient power delivery infrastructure. This paper discusses the design of a restructured electric distribution network that employs a large number of small distributed energy resources (DER) units, which can improve the level of system reliability and provide service differentiations. |

Hardware and Software Model Evaluation of a Dynamic Load Balancer for Mitigation of Current Unbalance in Distribution Circuits |
IEEE |
Current unbalance conditions are a concern to utilities and can negatively affect power quality and safe and reliable system operation if left untreated. Conventional solutions involve physical re-configuration and are typically challenging and less effective as these changes are temporary and will change as circuit and customer load habits evolve. As alternative, power electronic-based devices are promising solutions to mitigating current unbalance. This paper introduces the control theory behind one such power electronics-based Dynamic Load Balancer (DLB) and details the development of a transient software-based simulation model to allow for mitigation planning and performance evaluation in distribution circuits. The physical and software model for DLB were tested under a range of system conditions as verification of model accuracy and also evaluation of the device capabilities and performance. |

Microgrid Protection: An Overview of Protection Strategies in North American Microgrid Projects |
IEEE |
Microgrids have been proposed as an attractive solution to harness the benefits offered by distributed energy resources (DERs). However, despite their advantages, microgrids introduce new challenges to electric grids. In particular, they can impact conventional protection practices in distribution systems. This is mainly due to the presence of DERs, different microgrid operational modes, as well as various network configurations. This paper will provide an up-to-date overview and analysis of the protection schemes that have been designed and/or implemented in major North American microgrid projects. A brief overview of the microgrid protection issues and potential solutions are also presented in the paper to help designers with defining protection requirements for practical microgrids.

Microgrids Management |
IEEE |
The environmental and economical benefits of the microgrid and consequently its acceptability and degree of proliferation in the utility power industry, are primarily determined by the envisioned controller capabilities and the operational features. Depending on the type and depth of penetration of distributed energy resource (DER) units, load characteristics and power quality constraints, and market participation strategies, the required control and operational strategies of a microgrid can be significantly, and even conceptually, different than those of the conventional power systems. |

Predictive-Maintenance Practices: For Operational Safety of Battery Energy Storage Systems |
IEEE Power and Energy Magazine |
Changes in the Demand Profile and a growing role for renewable and distributed generation are leading to rapid evolution in the electric grid. These changes are beginning to considerably strain the transmission and distribution infrastructure. Utilities are increasingly recognizing that the integration of energy storage in the grid infrastructure will help manage intermittency and improve grid reliability. This recognition, coupled with the proliferation of state-level renewable portfolio standards and rapidly declining lithium-ion (Li-ion) battery costs, has led to a surge in the deployment of battery energy storage systems (BESSs). Although BESSs represented less than 1% of grid-scale energy storage in the United States in 2019, they are the preferred technology to meet growing demand because they are modular, scalable, and easy to deploy across diverse use cases and geographic locations.

Resilience Framework, Methods, and Metrics for the Electricity Sector |
IEEE Power & Energy Society Technical Report |
The resilience of the electric grid is the foundational building block for our decarbonized clean energy future. While the concept of resiliency is not new, its application to the electric grid is not as straightforward due to the lack of a consistent definition of resilience or a mature set of metrics by which resilience or its application can be measured. This report provides an overview of resilience definitions, including its relationship with reliability, the existing frameworks for holistically defining resilience planning and implementation process, and the metrics to evaluate and benchmark resilience. It provides recommendations on how to use those frameworks and metrics and evaluates technologies, tools, and methods to improve electrical system resilience. To provide a practical perspective to addressing resilience, the report includes the progress made by electric grid operators in collaboration with regional authorities to strengthen the resilience posturing, including some of the more common practices and use cases to increase system resilience, enhance broader preparedness, and to combat the impacts of the various external impacts to the electric power grid. Those use cases include Southern California Edison, Con Edison, Entergy, Florida utilities, San Diego Gas & Electric, ComEd, Austin Energy, as well as transmission and distribution system hardening practices, wild-fire risk mitigation lessons learned from California, and NERC reliability and cyber-security standards.

Grid Modernization for Public Power and Cooperatives |
Paper Authors: David G. Hart, Julio Romero Agüero, Bob Dumas, Donald Hall, and Mike Longrie |
More than 2,000 communities in the United States are served by public power utilities. These utilities typically provide electric, water, or gas service. Similarly, there are over 900 electric cooperatives that cover more than half of the nation’s landmass and serve more than 40 million people. Both public power utilities and electric cooperatives are vital parts of local economies, as they have a strong focus on serving their communities. Electric power grid and water services are delivery systems that interface to each home and business in a community. Historically, the utilities’ primary concern was the delivery of reliable power and water to its customers. However, the utility landscape is changing due to technical and societal drivers. |

Grid Resilience Assessment during Extreme Fast Charging of Electric Vehicles via Developed Power Hardware-in-the-Loop |
IEEE |
This paper presents a resilience assessment of a microgrid during extreme fast charging events of electric vehicles (EVs) via a power hardware-in-the-loop (P-HIL) testbed. The system under study is replicated in a real-time digital simulator (RTDS) to model its electrical features. Four 350-kW extremely fast chargers (XFC) and one 50-kW fast charger are considered in this test, as a combination of actual hardware and simulated chargers. To achieve a thorough breakdown of the fast-charging impact on the grid’s stability, an electric vehicle simulator, hereinafter known as Regenerative Electric Vehicle Actuation Node (RE-VAN™), is developed which provides numerous testing capabilities such as different charging models and power rating, dissimilar battery characteristics, etc. RE-VAN™ is deployed in the P-HIL testbed to enable the testing of the actual EV chargers in the setup. |
