Embodiment Construction
[0042] The present invention proposes a real-time control method of large power grid active power under the condition of limited wind power, the flow chart of which is as follows image 3 As shown, the data interaction mode between the dispatch center and the power plant is as follows figure 2 shown. This method comprises the following steps:
[0043] (1) Calculate the maximum active power of the wind farm
[0044] Accurately obtaining the limited amount of active power of wind farms is the key to realize the real-time control method of active power of large power grid. Before calculating the limited amount of active power of wind farms, the maximum active power of each wind farm should be calculated first. There are two methods for calculating the maximum active power of a wind farm. The first method is: divide the wind farm into multiple control areas according to geographical location, and set one or more benchmark wind turbines in each control area. The wind turbine i...
