Abstract
An electric circuit for regulating power transfer in a power grid includes a compensator circuit arranged to be connected between outputs of one or more power sources and a point of common coupling in the power grid. The compensator circuit is arranged to detect one or more electrical properties associated with the outputs and one or more electrical properties associated with the point of common coupling; and provide, based on the detection, a voltage output to emulate a resistor for suppressing filter resonance associated with the one or more power sources and to reduce equivalent impedance of the power grid.
