Method And Control System For Controlling A Voltage Source Converter Using Power-Synchronization Control

摘要

A method of controlling a grid-connected voltage source converter, VSC, using power-synchronisation control, wherein the method includes: determining a VSC current vector (i) based on a VSC phase angle (θ) which is determined based on an integration of a power control error, determining an active power producing current component (i_d^ref) of a reference current vector (i_ref) based on an active power reference (P_ref) for the VSC, determining the reference current vector (i_ref) based on the active power producing current component (i_d^ref), determining a damping component based on a virtual damping resistance (R_a), the reference current vector (i_ref) and the VSC current vector (i), determining a voltage vector (v) based on a VSC voltage magnitude (V) and the damping component, and controlling the VSC based on the voltage vector (v).
