10 Project Challenges Matching project goals and market place requirements Balancing Project Cost and Product Cost Bringing together the expertise of various partners Developing a product that could grow with new technologies

11 DC Microgrid- Efficient and Flexible Architecture Energy input agnostic Energy storage agnostic No reactive power transfer between inputs and load Only one device needs to be grid tie capable and certified Greater stability of output due to DC bus

12 Power Conversion Challenges Inverter : Bi- Directional for energy storage charging from grid Capable of handling islanding and grid tie at 1 MW Communications and control compatible Managing heat dissipation / generation The inverter needed to fit into a container Cost Renewable Energy Converters: Capable of running in current injection mode Converters capable of receiving set points from external source Managing heat dissipation / generation Cost

13 Energy Storage Converter Energy Storage Converters (1 MW each) UC and Battery Subsystem will use same type converter Designed by EPX Will control the bus voltage Used as charge controller for batteries and ultracaps

14 Energy Storage Strategy UltraCaps Used to balance transients Maintain the bus voltage Improve battery cycle life Batteries Longer term storage Commercially available cells size Can use other cells and chemistries Address serviceability and re-manufacturing Modular design

15 Battery Hierarchy Three Part Hierarchy Rack Highest level and complex functions unit Interfaces with Control System directly Drawer Intermediate level which monitors across four modules Module Benefit Basic building block Cell level protection and Gas Gauging Cost control Improved reliability

16 Cost Drivers Balance between system control and cost Electronics costs drive new chemistries Cell Considerations Initial cost Long term costs Space
