Handling small unobservable pockets in state estimation process

Handling small unobservable pockets in state estimation process

Most power systems have pockets where not all flows and injects are measured and therefore, a part of the system is not observable. The manner in which these pockets are handled during the state estimation process may make a significant difference in the outcome of the state estimation. This paper a...

Zusammenfassung:Most power systems have pockets where not all flows and injects are measured and therefore, a part of the system is not observable. The manner in which these pockets are handled during the state estimation process may make a significant difference in the outcome of the state estimation. This paper addresses the problems arising from such small pockets in a power system and provides a method for handling small pockets.
