Analysis on Active Power Fluctuation Characteristics of Large-Scale Grid-Connected Wind Farm and Generation Scheduling Simulation Under Different Capacity Power Injected From Wind Farms Into Power Grid

It is very important for the guidance of power grid operation and management to analyze the characteristics of active power of large-scale grid-connected wind farm and find out its variation law. Based on the recorded real-time operation data of large-scale wind farm connected with Inner Mongolia power grid in past two years and utilizing the methods of probabilistic statistical analysis and time series analysis, the fluctuation characteristics of active power generated by wind farm is analyzed, and its variation law as well as various factors impacting power grid operation are searched. According to the results from research and analysis, the key factors impacting the wind power capacity injected into power grid are found, and active power characteristics of power grid, which reveal after injecting different capacity of wind power into power grid, are summarized.
