  "textContent": "Embodiments herein provide a power control system (100) for controlling reactive power and/or active power in a power network. The power control system (100) is operatively coupled to the power network at a point of common coupling, PCC. The power control system (100) comprises a transformer (10) with at least three windings, in which a primary winding of the transformer (10) being connected to an input from the power network. The power control system (100) further comprises a voltage-source converter, VSC (20), being connected to a secondary winding of the transformer (10), wherein the VSC (20) is configured to work as a source or a sink of reactive power in the power network. The power control system (100) further comprises a Current Source Converter, CSC, (30) being connected to a tertiary winding of the transformer (10) and the CSC (30) is configured to handle power imbalance in the power network. [0002] Corresponding power compensator module is also disclosed.",
