Estimering af elsystemets tilstand

Estimering af elsystemets tilstand (PSSE) er en realtidsalgoritme, der estimerer spændingen og fasevinklen ved hver knudepunkt i et elnet ud fra et sæt støjende, redundante målinger. Introduceret af Schweppe i 1970, kombinerer den målinger (strømflows, spændingsmagnituder) med den fysiske strømflowmodel for at producere den mest sandsynlige systemtilstand. Tilstandestimering er grundlaget for moderne netkontrolcentre og giver operatørerne en nøjagtig digital repræsentation af det faktiske netværk.
