[0042] In order to describe the present invention more specifically, the technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0043] In this example, the IEEE39 node 10-unit system is used to verify the feasibility of the unit output optimization method of the present invention. figure 1 The wiring diagram of the 39-node 10-machine system is given in figure 1 The middle generator 39 is an ideal power source, which is used to equivalent to an infinite power grid, so the generator 39 is not considered when considering the transient stability margin constraints. For the above-mentioned power grid system, the unit output optimization method for improving the transient stability margin of the receiving-end power grid is adopted according to the present invention, and the specific process is as follows:
[0044] (1) Calculate the transient stability margin of each synchronous generat...
