Considerations for phasor measurement unit introduction in distribution system

We consider a distribution network evolution involving highly automated systems with PMUs. We argue that PMU-based grid control operations carried out autonomously would be faster and more cost efficient than current manned operations. Controls that are capable of optimizing the system could significantly improve performance and reliability. PMUs at distribution substations would support many of the applications required for moving towards a smart grid. Viewed from a broader perspective, it is recognized that the functions listed in this paper would have to be considered on a utility by utility basis.
