[0043] The active power quick adjustment method of the virtual small hydropower group of the present invention takes the actual power grid as the object, such as figure 1 shown. The regional power grid is connected to the main grid through a section composed of five tie lines. Area A is mainly powered by large thermal power plants, large-scale wind power plants and small hydropower plants. In the present invention, five small hydropower stations are selected to form a virtual small hydropower group. The core control algorithm process involved in the following steps 3 and 4 is composed of figure 2 give.
[0044] A method for rapidly adjusting active power of a virtual small hydropower group, comprising the following steps:
[0045] Step 1: Real-time calculation of the upper limit of active power adjustable capacity of the virtual small hydropower group lower limit Upload to the scheduler every 5 seconds;
[0046] Step 2: Scan base point power setting command P in real ...
