Ageto collaborated with the Laboratory for Energy And Power Solutions (LEAPS) at Arizona State University on a successful proposal for the Defense University Research-to-Adoption (DURA) initiative through the Office of Naval Research (ONR) titled ‘Electric Grid Reliability, Resiliency, and Security'. Ageto provided the Ageto Renewable Controller (ARC) to integrate the LEAPS microgrid assets and provide primary control of the microgrid power system.
The microgrid includes an Ideal Power 30C3 inverter with Blue Planet Energy LX HV LFP batteries. ARC provides the primary user interface, real-time controls, and capabilities necessary to test and validate various algorithms to enable the grid of the future to be more reliable, resilient, and secure. |

Headwater Center

Ageto contracted with Shell Microgrid Solutions to provide a monitoring and control solution at the Headwaters Center in Winter Park, CO. The Headwaters Center is an event and education center housed in a Civil War era barn, originally located in Ohio, that was disassembled, transported, and rebuilt in Winter Park, CO and turned into the Headwaters Center.
From the initial design, the facility was never connected to the electric utility grid, and is instead powered by an off-grid DC-coupled microgrid. Most of the facility load, including the air handling and HVAC systems, are directly powered from the DC bus. Facility AC loads are served by the grid-forming Princeton Power energy storage inverters. Backup power is fed onto the DC bus by natural gas generators; the AC output of the generators is converted to DC through Eltek rectifiers. ARC provides the primary user interface, real-time controls, and performance monitoring of the system which was not available prior to the commissioning of ARC. |

Sandbar Solar and Electric

Sandbar Solar's new office facility was built on an empty lot within the Santa Cruz, CA city limits. Instead of paying the high costs of an interconnection study with the local utility, the owner decided the new building would instead be powered entirely from an off-grid microgrid.
The microgrid was designed around the requirements of the local jurisdiction as well as the California air resource board, which limited the backup natural gas generator operating hours to less than 500 per year. Ageto performed system analysis to determine the optimal system and generator size, as well as providing the necessary data required during the permitting process. ARC provides the primary user interface, real-time controls, and system monitoring to maximize the renewable energy usage while utilizing the backup generator as necessary. Being near a residential area, the owner wanted to prevent the generator from running overnight. Ageto implemented an overnight 'quiet hours' function wherein ARC proactively runs the generator in the evening to charge the batteries if the available capacity is insufficient to carry the facility load overnight. ARC has been performing exceptionally since commissioning and is providing cleaner, cheaper, and more reliable power than the local utility. |
