AGI and state estimation

Estimating the power flow for distribution feeders helps the utility respond to the state of their distribution network. By installing AGI nodes at strategic locations in the distribution system, utilities can improve their on-line power flow measurement of their distribution feeders. By continuous monitoring of power flow measurements from a strategic number of AGI nodes utilities would be able to more effectively optimize energy delivery across the feeder network. Benefits include the following:


  • Feeder load balancing: operators can routinely transfer feeder sections to balance loads between adjacent feeders that have substantial load diversity
  • Improved service restoration activities: operators can make informed decisions when restoring service after a fault because the system will know the pre-fault load on each feeder
  • Feeder automation override: having more accurate load flow calculations, operators can determine whether blocking actions by feeder automation can be safely overridden
