Schools hybrid microgrid showcases ease of resource management
A DEIF AGC-4 mains controller monitors the school’s power demand and utility power use from a utility pole a short distance from the solar field, explains Brent Beissler. It communicates to the main controls room onsite via fiber link. There, two DEIF AGC-4 automatic genset controllers manage the peak shaving function. They communicate with an additional two ASC-4 solar hybrid controllers, which monitor the solar arrays.
“All these DEIFs communicate with one another instantaneously to do the peak shaving function,” he says.
“DEIF is the brains of this operation. Without DEIF we would have no way to strategically manage the energy and the demand output that’s being created onsite that could be intelligently used by the school.”
The school hopes to save 70% from its electricity bill with the hybrid renewables system. In its first months of operation, the system is working as planned, says Brent Beissler. “So far, so good.”
“They’re able to leverage money that would have gone to the power utility – instead of resources such as school programs and teachers.
“Our most precious resource is kids – students,” he adds. “Being involved in this project makes me feel good and socially responsible. We’re providing a solution that saves money, energy and the environment. It’s a rare triple win today.
