Unbalance compensation by optimally redistributing current

A method and system is described to determine unbalance compensating currents to be injected or consumed by a three-phase converter by current redistribution. First load- current is decomposed to outputs of at least negative- and zero-sequence components (I neg and I ze r), followed by determining a positive-sequence component (l pos,inv,i ) as a function of active power (P), reactive power (Q) and positive-sequence voltage (U), and determining a phase current, to be injected per phase and a neutral current.
