Conditioning of network impedance by insertion of a virtual inductance as an inherent feature of the converter control system has the potential to extend the range of stable operation of the overall system. This paper presents a scenario in which such potential is explored and its range of application is identified. It shows first that implementation of a virtual inductance is naturally suited for...
This paper presents a virtual flux-based method for voltage-sensor-less power control of voltage source converters under unbalanced grid voltage conditions. The voltage-sensor-less grid synchronization is achieved by a method for virtual flux estimation with inherent sequence separation in the stationary reference frame. The estimated positive and negative sequence (PNS) virtual flux components are...
This paper discusses voltage sensor-less grid synchronization and control of three-phase Voltage Source Converters under unbalanced conditions. First, it will be shown how the concept of “Virtual Flux” can be used for grid synchronization in unbalanced conditions. For this purpose, a method for separate estimation of positive and negative sequence Virtual Flux components will be reviewed and analyzed...
