SYSTEM AND METHOD FOR STABILIZING AN ALTERNATING VOLTAGE GRID

A system for stabilizing an alternating voltage grid has an inverter, which can be connected to the alternating voltage grid, and is configured to exchange reactive power with the alternating voltage grid. The system further has an inductor arrangement with variable inductor coils, which can be connected to the alternating voltage grid, and a control device, which is configured to control a reactive power in the alternating voltage grid by use of the inverter and by use of the inductor arrangement.
