The output of the power plant unit is limited by the actual unit operation state and the power grid section, so that various types of standby data of the power plant are calculated correctly, and the method has a decisive reference significance in the adjustment of the output of the power plant unit in response to different power grid operation requirements. However, due to differences of installation of power plants and differences of grid-connected voltage grades, the power plants in the whole network are directly managed by different scheduling mechanisms such as provincial and grid dispatching, and operation and control data of power plant units are stored in different scheduling mechanisms. In a single provincial dispatching system or a network dispatching system, accurate calculation of standby data of all power plants in the provincial region and the network region is difficult to realize.
