Phasor Measurement Units (PMUs) that allow operators to assess grid stability, advanced digital meters that give consumers better information and automatically report outages, relays that sense and recover from faults in substations automatically, automated feeder switches that re-route power around problems, and batteries that store excess energy and make it available to the grid later to meet customer demand.

When an underground fault or single loss of source occurs on an underground residential loop, the EdgeRestore system automatically locates and isolates the fault and reroutes power from an alternate source—all within 60 seconds.

Mehdi Hosseini, a data scientist with Beyond Limits, explained that AI can help the performance of the smart grid in two major ways. “One of them is accurate prediction of demand and generation, and the other is the real-time grid operation,” he said.

“Power utility companies rely heavily on long-term and short-term predictions,” Hosseini explained. “For example, every day they require an accurate prediction of the electrical demand of the next day. The electrical demand is heavily associated with weather data, business activities, and everything that affect those business activities. So, they go through historical data to find patterns and point associations between those two to have an accurate prediction.
