    Abstract : Popular Abstract in Swedish Det elektriska kraftsystemets uppgift är att ge konsumenter en säker och stabil energitillgång till lägsta möjliga kostnad. Sett ur ett ingenjörsperspektiv tillkommer några extra krav såsom att variationerna i spänning och frekvens skall vara acceptabla, samt att enstaka komponenters kapacitetsgränser ej överskrids.
