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 sustained and healthy development of wind power and the security and stability 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 need to carry out uncertainty analysis and uncertainty evaluation methods research of wind power grid-integration test.
