Powering distribution optimization with digital energy
GE has the proven solid foundation. With scalable and performant distribution power apps currently in production worldwide, utilities are empowered to solve current challenges as well as position themselves for the future. GE’s systems have gone well beyond pilots to full-scale production rollouts, delivering valuable outcomes to our customers daily during business as usual as well as severe weather events via Distribution Power Flow (DPF), Distribution State Estimator, Integrated Volt-Var Control (IVVC), and Fault Location, Isolation and Service Restoration (FLISR).
In one example, a North American IOUs runs our core network analysis engine to locate the complex voltages at all nodes and the power flows through all feeder segments in the distribution system. They currently have 850 distribution substations continuously solving real-time DPF with BLA/SCADA inputs on a periodic basis and upon switching events.
They’ve been impressed with how close the estimated solutions of the DPF are matching up with the SCADA measurements.
Another North American GE IOU customer is running FLISR in production with closed loop operation on every one of its 2200 feeders. Plus, the solution was implemented in less than a year. During a single thunderstorm, FLISR restored 9488 customers in less than 2 minutes; the following week it restored 5308 customers in less than 1.5 minutes.
In a single year, this customer had 32 successful FLISR events with a 3-minute average restoration time, with approximately 20,000 customers restored automatically.
GE customers have seen positive outcomes. Some highlights include:
- Up to 30% additional reduction in SAIFI over scripted automation programs
- Up to 3% reduction in voltage for greater network efficiency
- Up to 20% increase in renewable exports onto the grid
