6. Microgrid Concepts

7. Microgrid and OE’s Performance Target Definition by Microgrid Exchange Group OE’s 2020 Performance Target A microgrid is a group of interconnected loads and distributed energy resources within clearly defined electrical boundaries that acts as a single controllable entity with respect to the grid. A microgrid can connect and disconnect from the grid to enable it to operate in both grid-connected or island-mode. Develop commercial scale (<10MW) microgrid systems capable of reducing outage time of required loads by >98% at a cost comparable to non-integrated baseline solutions (UPS + diesel genset), while reducing emissions by >20% and improving system energy efficiencies by >20%

8. Various Microgrid Configurations Possible • Consumer Microgrid—single consumer with demand resources on consumer side of the point of delivery, (e.g. sports stadium) • Community Microgrid— multiple consumers with demand resources on consumer side of the point of delivery, local objectives, consumer owned, (e.g., campus, etc.) • Utility Microgrid—supply resources on utility side with consumer interactions, utility objectives Microgrids are “Local Energy Networks”

9. Microgrid Markets • Municipalities • 1327 in the US, 961 under 300,000 residents • University campuses • 8,520 in the US • Military facilities (25% renewables goal) • 440 facilities worldwide • Industrial and commercial parks • ~15,000 in the US with a capital size of $10M to $100M • Utilities with special needs • Over 900 rural electric cooperatives, over 1200 municipal utilities, ~250 investor-owned utilities, and many public power utilities • Other campuses (hospital, state agencies, etc) - Not quantified to date

12. Some Challenges and Risks

13. 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”

23. CERTS Microgrid Test Bed Objective Expand CERTS Microgrid concepts to address system integration challenges presented by need to accommodate intermittent, distributed renewable electricity sources within utility distribution systems. Technical Scope The CERTS Microgrid Test Bed is being expanded through the addition of new hardware elements: (1) a CERTS compatible conventional synchronous generator; (2) a more flexible energy management system for dispatch; (3) intelligent load shedding; (4) a commercially available, stand-alone electricity storage device with CERTS controls; and (5) a PV emulator and inverter with CERTS controls.
