1 Government & Military Smart Grids & Microgrids Symposium Topical Report on DOE Smart Grid ARRA Microgrid Projects Steve Bossart Senior Energy Analyst April 9, 2014 Arlington, VA

2 2 Topics DOE Topical Reports on Smart Grid ARRA Projects Microgrids Motivations and Challenges Results from DOE Microgrid Projects

3 3 Topical Reports

4 4 Analyze results from SGIG, SGDP, and RDSI 1.Summarize results Report similarities, differences, and range of results Rationalize results Common best practices and lessons learned Connect investments with functions with benefits Connect smart grid with improved DER functionality 2.Educate

5 5 Topical Reports Microgrids Dynamic Line Rating Phasor Measurement Units Distributed Energy Resources Transactive Energy Communications Conservation Voltage Reduction PUC Filing Review Consumer Behavior Studies AMI/smart meter –O&M –Peak load reduction –Volt/VAR optimization –Reliability Applications and Benefits of Smart Meter/AMI Others?

6 6 Microgrids Definition, Concepts, Motivations, Benefits, Technologies & Challenges

7 7 Includes DER & Load Defined electric boundaries Single controllable entity Connect and disconnect from grid Grid-connected or island-mode Microgrids & Smart Grids

8 8 A Possible Future Distribution Architecture Distribution Control Industrial Microgrid Utility Microgrid Commercial Park Microgrid Campus Microgrid Municipal Microgrid Military Microgrid

9 9 Motivations for Microgrids Reliability –Impact on business –Grid reliability is worsening Resiliency –Ability to withstand challenges and continue operation –Value of microgrids during Superstorm Sandy Economic –Best energy mix is 80-89% from microgrid and % from main grid Sustainability/emissions reduction

10 10 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

11 11 Cost of Electric Service $363 billion is annual electric bill in US (2013) $200 billion is paid by commercial and industrial firms Value of business losses is $80 - $150 billion annually (LBNL and EPRI studies) Interruption Cost Estimate Calculator (ICE)

12 12 Types of Microgrids End user Utility distribution Remote/island systems Size 2 MW to 40 MW are economical – average and above cost of electricity (COE) < 1 MW are economical where COE is higher -Hawaii, Alaska, Northeast Portfolio Mix Balance resources with high capital cost and low O&M with resources with low capital cost and high O&M

13 13 Common Technologies in 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) Power inverters Consumers Plug-in electric vehicles and charging stations (PHEV/PEV) Smart appliances & programmable thermostats (DR/DD) Home Area Networks & In-Home Displays Energy management systems

14 14 Barriers to End User Microgrid Deployment Very young in financing lifecycle –Majority of microgrids involve third-party financing –Requires long-term service agreements (PPA) Regulatory environment has not been favorable –Microgrids must be “good citizens” –Conflict in allocation of utility costs to accommodate microgrids Value proposition may be unclear Technology –Optimize controls to improve value –Rapidly improving technologies (e.g., energy storage) Private wire laws
