1. A system for stabilising a power grid, comprising:
a generator, configured to provide power to the power grid, the power having an active power component and a reactive power component;
a power line, configured to transmit power from the generator to the power grid;
a thyristor controlled braking resistor (TCBR) arranged on the power line and configured to control a power drawn from the generator; and
a capacitor electrically connected in series with the TCBR between the generator and the power grid;
wherein the capacitor is configured to compensate for at least a portion of a reactive power component absorbed by the TCBR.
