Abstract

See full text

This disclosure relates to systems and methods for controlling a wind converter for a weak electrical grid. In one embodiment of the disclosure, a system for controlling the wind converter includes a wind converter connected to an electrical grid at a point of connection (POC) and operable to transfer a power to the electrical grid. The system includes a first control loop operable to calculate, based on electrical grid parameters and wind converter characteristics, a voltage reference to be generated by the wind converter. The system includes a second control loop to convert, based on the electrical grid parameters, the voltage reference into a current reference. The second loop converts the angle information of the voltage reference into a voltage at the POC. The system includes a third control to regulate, based at least on the current reference, the power transferred by the wind converter to the electrical grid.
