  5. 5. What is a Military Grid? • Military Microgrids have been around for a long time!Navy, Marine Corps units help avert San Diego power outages, October 25, 2007,By Petty Officer 2nd Class Mark LogicoSAN DIEGO – The U.S. Navy and Marine Corps helped San Diego residents avoid potential poweroutages during the San Diego firestorm crisis, Oct. 24. “We appreciate the Navy and MarineCorps’ response to our urgent request for electricity demand reduction,” said Michael Niggli,chief operating officer for San Diego Gas & Electric. Within three hours, more than 30 U.S. Navyships shifted from pier-connected, shore powered to organic shipboard power, significantlyreducing more than 100 megawatts of electrical strain on the San Diego power grid.

  7. 7. A Microgrid Definition *A Microgrid is a localized, scalable, and sustainable power grid consisting of an aggregation of electrical and thermal loads and corresponding energy generation sources capable of operating independent of the larger grid. Microgrid components include; distributed energy resources (including demand management, storage, and generation), backup power systems, control and management, secure network and communications infrastructure, and assured information management.When renewable energy resources are included, they usually are of the form of wind power, solar, hydro, geothermal, waste-to-energy, and combined heat and power systems. Microgrids perform dynamic control over energy sources enabling autonomous and automatic, self healing operations. During normal or peak loading or at times of power grid failure the Microgrid can operate independently from the larger grid and isolate its generation nodes and loads from the disturbance without affecting the larger grid’s integrity. Independent Microgrid operation can offer higher reliability and cost efficiency than that provided by traditional grid control.The Microgrid is both an energy market consumer and provider of electrical power. Microgrids interoperate with existing power systems, information systems, and network infrastructure. The Microgrid may take the several forms, such as a utility metropolitan area, a shopping center, industrial park, college campus or a small energy efficient community.* Spectrum Management for Microgrids, R.

  9. 9. Microgrid Classification *• Utility Managed and owned by a utility. Microgrid has distributed generation resources in multiple areas of the utility jurisdiction and includes several Microgrids that can be networked and islanded from the utility grid. Includes different types and sizes of energy storage systems and Microgrid renewables complement utility bulk energy generation. Peaker generators used for renewable intermittency. Utility scale EMS.• Community/Metropolitan/Regional The word “community” implies a geographical region that includes residential customers, but can include Commercial & Industrial. May have several Microgrids that can be networked and islanded from the utility grid. Various geographical sizes with local utility power.• Commercial/Industrial Established Microgrids, some with battery or UPS back-up. There are estimated 455 megawatts (MW) of these vintage Microgrids are currently online in the United States. Unlike today’s conceptual state-of-the-art models, these initial designs for the heavy and light industry still feature centralized controls and fossil-fueled generation sets. May include strip malls and technology parks. * Edited from “Microgrid Technology”, Pike Research Report, 2009. Copyright @ The University of Texas at El Paso 9 9
  10. 10. Microgrid Classification * (Cont)• Institutional/Campus(es) At present, estimated 322 MW of college campus Microgrids are up and running in the United States, with more sophisticated state-of-the-art Microgrids in progress. In the U.S., 40% of future Microgrids will be developed in this market segment, adding 940 MW of new capacity valued at $2.76 billion by 2015.• Remote-off Grid Systems This segment represents the greatest number of Microgrids currently operating globally, but it has the smallest average capacity. While many systems have historically featured diesel distributed energy generation, the largest growth sector is solar photovoltaics (PV). Wind and solar farms are common in rural areas, but transmission is a problem. Waste-to-energy systems are developing in this type of Microgrid.• Military/Federal Complexes Military Microgrids are just being developed in the DoD and Federal complexes. Ownership may be by tenant or outside developer. They are integrating Renewable Distributed Energy Generation (RDEG) to secure power without being dependent on any supplied fuel or local utility. Federal building complexes with energy storage systems are in this class of Microgrids. * Edited from “Microgrid Technology”, Pike Research Report, 2009.

Reality of Installation Military Grids• Microgrid technology is not a problem in deployment of Military Microgrids• Federal and DoD land acquisition can involve several agencies and delay deployments• Silo organizations in military installation management and operations are an issue• Private finance developers for DoD projects are required• Energy Management Systems (EMS) for Microgrids in military installations need to be integrated with base operations and network operation centers• Interconnection and isolation with local utility providers may be problematic• Microgrid ownership must provide a local EMS for control and management Copyright @ The University of Texas at El Paso 16
