The teachings relates to a method (30) performed in a control device (11) for controlling a power compensation arrangement (1) comprising a voltage source converter (2) and one or more power compensation branches (4, 5, 8), each power compensation branch (4, 5, 8) comprising a thyristor controlled reactor, a thyristor switched reactor or a thyristor controlled capacitor. The voltage source converter (2) and the one or more power compensation branches (4, 5, 8) are connected to a same busbar (12). The method (30) comprises: detecting (31) a request in an electrical power system (20) to which the power compensation arrangement 1 is connected; determining (32), based on the request, a need for reactive power supply to the electrical power system (20); providing (33) reactive power by means of the voltage source converter (2) and/or by one or more of the power compensation branches (4, 5, 8); and compensating (34), by means of the voltage source converter (2), any disturbances caused by the power compensation branches (4, 5, 8) when providing the reactive power to the electrical power system (20). The teachings also relates to corresponding devices. |
