wind power grid-integration test; uncertainty components; uncertainty evaluation method
The influence of large-scale wind power integration on the safe and stable operation of a power system cannot be ignored. In order to safeguard the sustainable and healthy development of wind power and the secure and stable operation of power system,it is important to conduct the wind power grid-integration test. Uncertainty is an important indicator of the test results to ensure reliability,accuracy,and test capabilities,and it is urgent to carry out uncertainty analysis and uncertainty evaluation methods research of wind power grid-integration test. Through the study of relevant standards,the project and test methods of wind power grid-integration are presented. Uncertainty components of the major test results of the power,harmonics and flicker are analyzed. Finally,the uncertainty evaluat
