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