  • Microgrid Controllers: Their Important Role in the System [From the Editor]
    Microgrid meets resiliency and reliability needs by effectively providing an uninterruptible power supply to critical loads. They may also improve environmental performance by facilitating renewable resource generation, such as photovoltaics and combined heat and power plants. Microgrids afford opportunity for economically delivering energy, capacity and ancillary services. As a result of all those and other factors, several policy makers are actively promoting microgrid development.

  • Microgrid Controllers: The Brain, Heart, & Soul of Microgrid Automation [Guest Editorial]
    It should be noted that the work reported in these articles represent only a small sample. Globally, hundreds of projects are occurring with different goals and objectives in mind leading to new concepts such as smart cities, ecocities, smart communities, and rural microgrids. In terms of the future, researchers are already exploring new types of microgrids such as dc microgrids (witnessing a rebirth after more than a century), hybrid microgrids, and others. In terms of hardware, as part of automation devices, we are already witnessing new sensors such as micro phasor measurement units and new digital protective and control devices and systems under the intelligent electronic devices rubric. We are confident that newer architectures for control and protection will also evolve with time. Advanced and adaptive protection is an example of this evolution. The development of new materials and attendant technologies will make the difference for the future. If the recent past is an indicator, the future will be brighter for microgrids and their controllers.

  • Microgrid Controller Initiatives: An Overview of R&D by the U.S. Department of Energy
    The microgrid is a concept for which the controller is the defining and enabling technology. Indeed, the microgrid may be defined as the resources-generation, storage, and loads-within a boundary that are managed by the controller.

  • The Need for Standardization: The Benefits to the Core Functions of the Microgrid Control System
    As the penetration of Distributed Energy resources (DERs) in distribution systems increases, their integration and interconnection to the grid, and their impact on the grid, need to be addressed in a coherent and structured manner. In the case of a large penetration, DER s can be integrated by aggregating the units using a DER energy management system (DERMS) or can form part of the devices constituting a microgrid, in which case they are managed by the microgrid control system. This article stresses the need for standards to facilitate the large-scale deployment of DER in the distribution system within a microgrid.

  • Microgrid Controllers : Expanding Their Role and Evaluating Their Performance
    Microgrids have long been deployed to provide power to customers in remote areas as well as critical industrial and military loads. Today, they are also being proposed as grid-interactive solutions for energy-resilient communities. Such microgrids will spend most of the time operating while synchronized with the surrounding utility grid but will also be capable of separating during contingency periods due to storms or temporary disturbances such as local grid faults. Properly designed and grid-integrated microgrids can provide the flexibility, reliability, and resiliency needs of both the future grid and critical customers. These systems can be an integral part of future power system designs that optimize investments to achieve operational goals, improved reliability, and diversification of energy sources.

  • Microgrid Controller Design, Implementation, and Deployment: A Journey from Conception to Implementation at the Philadelphia Navy Yard
    TNY in Philadelphia offers a diverse composition of load, asset, and customer class leading to multiple categories of microgrid manifestations. This has been one of the most challenging aspects of this project. However, this allowed the project team to innovate a generalized microgrid system and the testing methodologies to address the diverse scenarios required for readiness verification. TNY microgrid system design activity provides novel design constructs that one can leverage at the grid-design level across different classes of microgrids. The development of a hierarchal microgrid management control system allows the monitoring and control schemes at different layers. The architecture and design provide the flexibility and capability to meet the communication and control performance for the next generation of microgrid systems. In addition, a newly developed microgrid test methodology has produced a robust framework for testing the next generation microgrid system. The forward thinking and vision of the PIDC described in TNY energy master plan is the foundation of this work. The project teams combined experience of control room energy management, grid substation automation, and electric market management turned the PIDC's vision into reality. TNY, including the GE hierarchal microgrid management system, is visited by various industry leaders, regulators, and utility representatives across the United States and the world.

  • Networked Microgrids: Exploring the Possibilities of the IIT-Bronzeville Grid
    Bronzeville is a community located in the city of Chicago that features a diverse historic district with essential city services, residential housing, and educational institutions. The Bronzeville neighborhood houses the headquarters of the Chicago Police and Fire Department, De La Salle Institute, Illinois College of Optometry, Boulevard Care Center, Chicago Public Library, Pilgrim Baptist Church, Bronzeville Nursing and Living Center, Chicago Military Academy, Pentecostal Church, Perspectives Math & Science Academy, and other institutions. The area provides an ideal location for the continued refinement and development of advanced electric power services, which can be demonstrated through the implementation of a community microgrid: the Bronzeville community microgrid (BCM). The BCM is the backbone of a planned community of the future, where residents and critical facilities enjoy a sustainable environment and utilize innovative smart grid products. The BCM can serve as a pilot project for demonstrating the merits of instituting Chicago as a smart city. Distribution automation devices capable of fault interruption and sectionalization will be strategically deployed so that a fault would only result in a local outage rather than an interruption to the entire area. The BCM operation will comprise several types of distributed energy resources (DER s). A battery energy storage system (BESS) located in close proximity to photovoltaic panels provides an effective means to mitigate the variability of renewable energy. The BESS is also effective in improving the power quality at customer sites.

  • Microgrid Control Strategy: Derived from Stakeholder Requirements Analysis
    The energy market is recognizing that both distributed generators and controlled loads are valuable assets when properly integrated into a utility's power and communications networks. However, the proliferation of these distributed energy resources (DERs) creates challenges for utilities when interconnected to their networks. Traditional operational models, including sensing and computational tools, will not be enough to meet future needs. Specifically, the monitoring and control layer (some call it the IT layer) will need to be transformed to adequately integrate DERs.

  • The Emerging Transactive Microgrid Controller: Illustrating Its Concept, Functionality, and Business Case
    Microgrids were initially popularized to increase resiliency of real-time electric power systems regarding natural disasters. With the changing electricity industry landscape in recent years associated with cost-effective distributed energy resources (DERs), such as rooftop solar photovoltaic (PV) systems, distributed storage, and increased active demand-side participation, microgrids are finding their place in this landscape as economic transactive agents capable of providing a variety of services to the mutual benefit of the microgrid, the distribution utility, and the power system at large. Presently, microgrids can participate in distribution utility demand response (DR ) and other demand-side programs, provide energy and ancillary services (ASs) to the bulk power system and markets and in some cases provide voltage support and resiliency to neighboring facilities. The emergence of the new distribution system operator (DSO) construct and the transactive energy (TE) paradigm, however, will further enhance a microgrid's capabilities to participate in retail, wholesale, and bilateral markets when operating in a grid-connected mode.

  • Simulation Technology: The Evolution of the Power System Network [History]
    In 1915, Nature magazine published a short paper, "The Principle of Similitude." The author, Nobel-Prizewinning physicist John Strutt, Lord Rayleigh, introduced his paper by stating, "I have often been impressed by the scanty attention paid even by original workers in physics to the great principle of similitude." He went on to propose many examples of physical behavior that could be easily predicted through an existing understanding of similar physical phenomena. The principle of similarity he referred to has, in recent years, been important in the field of fluid dynamics, where the consideration of scale models must be analogous not only in shape to their real-world counterparts but in their dynamic interactions with surrounding media over time.

  • Microgrid Control Systems: A Practical Framework [In My View]
    The growing interest in microgrids has brought a great level of focus, creativity, and investment in the development and commercialization of microgrid control systems. The primary value propositions for microgrids are improving reliability and resiliency, enabling renewable generation integration at a higher penetration level than normal, enhancing efficiency, and the economic dispatch of distributed generation to reduce operation and maintenance costs and create new revenue streams (for instance, through participation in the energy or ancillary service markets). All of these efforts emphasize the need for a microgrid control system that can operate the system autonomously in a coordinated fashion to achieve predefined performance goals.
