METHOD FOR ANALYZING INFLUENCE OF FLUCTUATION IN OUTPUT POWER OF WIND FARM ON POWER GRID

摘要

A method for analyzing the influence of fluctuation in the output power of a wind farm on a power grid.The method includes the following steps: calculating predicted regional control error (ACE) fluctuation data for the next moment according to the predicted wind power data of a single wind farm for a regional power grid, the actual wind power data for the regional power grid, and the ACE fluctuation data for the regional power grid; and comparing the predicted ACE fluctuation data for the next moment with an ACE threshold; if the predicted ACE fluctuation data for the next moment exceeds the ACE threshold, then an alert is carried out.In the foregoing, ACE is an error value caused by factors such as the current load, power generation, power reception and frequency of the power grid, and this error value reflects the power balance of the region.The method provides a basis for large-scale grid integration and scheduling of the wind power, which is helpful for improving the utilization efficiency of a green resource.
