New wind storage power generation system black start control strategy research

The application of large-capacity machine units and long-distance power transmission lines leads to frequent major power failure in the world and it makes power grid security become more and more important. Power grid needs to be prepared for rapid restoration of power supply when full power grid failure happens, namely, it needs to be prepared for dealing with black start. Modern power system should be equipped with appropriate system restoration plan dealing in full power system failure. In this paper, based on the study of wind storage new power generation system model and the analysis of specific case in Liaoning Grid, it complies effective start strategy and conducts stability check of the small system formed after the start.
