Abstract
There is disclosed herein a STATCOM (20), configured to be connected to an electrical power network system (1) comprising at least one inverter-based resource (3) connected to a transformer (4) by an AC transmission line (5). The transformer is connected to an electrical power network (2). The STATCOM is connected between the AC transmission line and the transformer. The STATCOM comprises a converter (22) and a grid forming control system (10) comprising a virtual admittance controller (12) configured to provide a virtual admittance current (I<sub>VA</sub>), a voltage flicker balancer controller (14) configured to provide a current reference (I<sub>ref</sub>) based on a current measured in the electrical power network system, and a current limiting controller (16) configured to provide a voltage reference (V<sub>ref</sub>) for operating the converter of the STATCOM based on the current reference and the virtual admittance current. The present disclosure further relates to an electrical power network system.
