2 Intelligent Microgrids An integrated energy system intelligently managing interconnected loads and distributed energy resources, including renewables, that operates seamlessly with an existing power grid or in an independent mode Operational Reduce fuel consumption in theater reduce logistics, cost, and lives lost Increases Efficiency Reduce fuel consumption Peak Shaving - Decrease cost Increases Reliability Optimally manage resources Real-time monitoring/control Provides Security Advanced cyber solutions Bulk grid independent capability Reduces Carbon Footprint Easily integrates renewables Fixed Installation Enhance energy security: Surety, Survivability, Supply, Sufficiency, Sustainability Flexible Solution Addresses Operational and Facility Energy Challenges 2

3 Key Characteristics of an Intelligent Microgrid Intelligent centralized and distributed control Algorithms to optimize operation Fast and secure communications Resilient fault coordination and recovery Plug-and-play integration of sources and loads Multi-mode operation based on customer requirements Adaptively Meets the Needs of a Wide Variety of Customers 3

4 Project Development Site Analysis -Facility -Mission -Resources -Stakeholders Design Tool Component Library Power & Energy Balance Risk Analysis Renewables Calculator Financial Analysis BLCC, eroi Preliminary Design Performance Metrics Financial Metrics Distributed Sources: Diesel/Gas Gen, PV, Wind, Hydro, Geothermal, etc Utility Grid HEV / PHEV Integration & Control Critical Loads D/R Algorithms AMI Microgrid Controller Control Algorithms AMI AMI/ MDMS Traditional Loads Energy Storage Procurement Contract Mechanism/ Financing Drawings Site Plan Line Diagrams Req s & Spec s Microgrid Architecture to Meet Customer Specific Needs 4

5 Planning Tool User selects a site and locates relevant legacy and new equipment. Each piece of equipment has a screen for inputs. Creates Microgrid Architectures Quickly and Easily 5

6 Planning Tool: Scenario Evaluation GRID-OPERATION Balances load demand with supply availability on a 15 minute or hourly interval for the whole year. Calculates run hours, fuel usage, operating costs for the standard operating case. GRID-FAILURE Days Calculates how long loads can be supported based on the available resources for each month in different risk cases, such as loss of utility power. Days Evaluate Microgrid Performance with Detailed Output 6

7 Financial Analysis & Planning Estimates the capital expenditure for a project implementation. Estimates the operating costs and savings of various options. Results can be used to fill out the BLCC or eroi forms. Evaluates different contracting and financing mechanisms, such as PPA, UESC, ECIP, ESPC. Planning Tool Creates Financial Output for Contracting Evaluation 7

12 Energy Security Before A few critical loads backed up Loads usually running <20% of generator capacity. Generator running very inefficiently. Building ineffective during power outage only preserved. Generator maintenance power is dumped After Critical loads backed up and power available to others (not necessarily at the same time) Generator loaded more optimally. Building can continue performing its mission during a utility power outage. Generator maintenance power is used. Graceful Power Degradation Preserves Mission Critical Function 12

13 Renewable Energy Before Solar PV system works only when the utility grid is on At attempt to make the solar work with the generator required limiting the solar inverter to 20% of the systems rated power. After Solar PV system works with and without the utility grid The PV system can operate at full output when running with the generator thus extending the survivability and allowing more loads to be powered. Even more PV can be added. Renewable Energy Increases the Duration of Mission Critical Functions 13

14 Cost and Savings Capital costs include switches, controls and energy storage (generator and existing solar) Peak Shaving and Demand Response capability can save ~$40k per year from electric bill for this one building Greater savings opportunities as utility costs continue to rise Improved Efficiency Pays for Improved Security 14
