AGIDC – Adaptive Grid Impedance Droop Control

Due to the increasing number of decentralized power feeder it becomes more and more difficult to keep up the stability of the power grid. For power feeder in low- and medium voltage power grid the ohmic part of the impedance gains more influence than in the transport grid. This means that the coupling of frequency and voltage to active and reactive power can be completely inverted compared to the common droop control. AGIDC solves this problem of droop control for decentralized power feeder in low- and medium voltage grids. AGIDC – with an impedance dependent static function – provides a droop control in a general form. The power feeding can be adapted to changing grid impedances and to other requirements from the transport grid.
