  3. Microgrid Concepts

  4. Microgrids & Smart Grids Microgrid Distributed Generation E-Storage Load Central Generation Load Transmission Distribution Includes DER & Load Defined electric boundaries Single controllable entity Connect and disconnect from grid Grid-connected or island-mode Distributed Generation E-Storage

  5. A Possible Future Distribution Architecture Municipal Microgrid Distribution Control Utility Microgrid Industrial Microgrid Campus Microgrid Military Microgrid Commercial Park Microgrid

  6. Why Microgrids? • Support integration of smart grid & renewables • Ease application of combined heat & power • Local generation reduces electricity losses • Disperses investments between central and local assets • Assist in reducing peak load • Serve critical loads • Provide local power quality & reliability • Promotes community involvement & energy independence • Provide local power during outages • Supports main grid • Provide ancillary services to main grid • Manage variability of loads and renewables locally

  7. Some Challenges and Risks

  8. Challenges to a Smart Grid • Businesses, state regulators, and consumer advocates are unconvinced of the value of smart grid technologies due to lack of performance data on costs and benefits • Insufficient or inadequate technologies, components, and systems to leverage IT potential of smart grid • No established standards for interoperability of systems and components • Insufficient cyber security for a smart grid architecture • Lack of a skilled workforce to build, install, operate, and maintain systems and equipment • Consumer understanding of the electrical infrastructure and opportunities enabled by smart grid technologies • Change management – vision, alignment, education, metrics • Future proofing – communications • Shift in regulatory paradigm – least cost, “used and useful”

  9. DOE OE Microgrid Demonstration Program

  12. DOE OE Primary Microgrid Project Locations Battelle IIT Mon Power Chevron Ft Collins LADWP SCE SDG&E RDSI SGDP

  13. Smart Grid Demonstration Program (SGDP) Number of Projects • Demonstrate emerging technologies (including energy storage) and alternative architectures • Validate business models • Address regulatory and scalability issues • Large projects: $20M-$89M Small projects: $720K-$20M (Federal share) • 4-year projects (average) SGDP Recipient Types Non-Profit, 9%

  14. Common Objectives Among DOE’s Microgrid Projects • Reduce peak load • Benefits of integrated DER (i.e., DG, DR, e-storage) • Ability to integrate variable renewables • Operate in “islanding” and “grid parallel” modes • Import and export capabilities • Two-way communications (frequency, verification, data latency) • Data management • Price-driven demand response • Dynamic feeder reconfiguration • Outage management (i.e., number, duration, and extent) • Volt/VAR/frequency control • Balance distributed and central control • Cyber security • Interconnection and interoperability • Defer generation, transmission, and distribution investments

  15. Common Technologies Among DOE’s Microgrid Projects Generation and Energy Storage Renewable energy (PV, wind) Distributed generation (microturbines, fuel cells, diesel) Combined heat and power Energy storage (thermal storage, batteries) T&D Communications (wireless, PLC, internet) Advanced metering infrastructure & smart meters T&D equipment health monitors (transformers) Consumers Plug-in electric vehicles and charging stations (PHEV/PEV) Smart appliances & programmable thermostats Home Area Networks & In-Home Displays Energy management systems

  20. CERTS Microgrid Demonstration at St. Rita Jail

  21. CERTS Microgrid Demonstration at St. Rita Jail Results • 14% peak reduction • Fuel cell (1 MW) • Photovoltaic (1.2 MW) • Battery (2MW; 12MWH)

  22. Cloudy Spring Day

  23. Goals of the IIT Microgrid Project • 50% peak demand reduction • 20% permanent demand reduction • Demonstrate the value of Perfect Power • Cost avoidance and savings in outage costs • Deferral of planned substations • New products and commercialization • Replicable to larger cities • Promotion of energy efficiency and cleaner cities

  24. Loops at Perfect Microgrid

  25. Components of IIT Microgrid • An 8 MW combined cycle gas unit • 1.4 MW of PV cells on building rooftops to supply portions of campus load. • 500-kWh ZBB storage increases the reliability and efficiency of the microgrid. • An 8 kW Viryd wind turbine is installed on the north side of the campus in Stuart soccer field. • Electric vehicle charging stations facilitating small energy storage and providing green energy for electric vehicles.

  26. Peak Load Reduction Capability at Microgrid

  27. Optimal Control of IIT Microgrid

  28. Reliability Evaluation – Stochastic Solution • The installation of HRDS and storage will lead to the best expected reliability and economic indices.
