Direct Current Microgrid Demonstration Project at Pope Army Airfield, NC



Melvin L. Cline, Zapata Group, Inc.



 The presentation will highlight the design and construction for a DC Microgrid constructed at the Hercules Physical Fitness Center (Building P-402) at Pope Army Airfield, NC.  The project objective was to demonstrate the benefits of a Bosch Direct Current (DC) Microgrid Building Energy Management Platform in a high-bay induction lighting application and a DC fan application.  The DC Microgrid is powered by rooftop solar arrays with a total generation capacity of 147 kW, a 30kW AC/DC Power Server, and a 105kWh battery energy storage system.  Of the 147kW rooftop solar capacity, 14kW directly powers the dedicated DC building lighting and ventilation loads with the remaining PV capacity available to recharge batteries and provide AC power to the building or the grid.  The DC building load consists of (44) 260w DC induction light fixtures and (4) DC Big Ass Fans.  Four 260W AC induction light fixtures serve as a reference system, as well as emergency lighting in the gymnasium.  The AC Reference System is used for performance comparisons between the AC and DC high-bay induction lighting systems.  The Gateway provides maximum power point tracking (MPPT) algorithms and circuitry that keeps the PV System operating at the highest efficiency possible regardless of weather conditions.  The Gateway also manages the solar-synchronized loads (SSL) function, including load-balancing, load sheading, and device-management capabilities to reduce loads during periods of reduced PV power, while the dc building loads are not affected.  They respond to and attenuate “peak-to-valley” changes during varying solar energy production, including cloud-shading events. 



 Mr. Cline has 40 years of professional engineering and construction experience in the electric utility industry, federal, and private sectors. He is a graduate of UNC Charlotte and a licensed professional engineer in NC and CT, a licensed General Contractor in NC and SC, and a Certified Energy Manager (CEM). He currently serves as Manager of Energy Services at the Zapata Group. His primary responsibilities include business development primarily targeting utility industry clients and Department of Defense. He also serves as program manager for energy projects. Past energy projects include evaluation of renewable energy generation technologies, energy conservation, microgrids, and development of technical requirements for renewable energy RFPs.  Previous experience includes 27 years as an engineer with Duke Energy where he was responsible for evaluation of emerging energy technologies.
