Abstract
An arrangement, which is connectable to an alternating current (AC) power transmission system, comprising a static synchronous compensator device having a converter unit and an energy storage unit connected with the converter unit; a power absorption device; and a control device connected with the static synchronous compensator device and with the power absorption device. The control device is configured to control the static synchronous compensator device to exchange power with the AC power transmission system, and to control the power absorption device in dependence of a state of charge of the energy storage unit and a state of the power transmission system. The control device is configured to determine whether there is a need to absorb active power from the AC power transmission system in excess of what the static synchronous compensator device is absorbing and, in case of a need, control the power absorption device to absorb active power.
