Abstract :
This Paper puts the power system into an affine coordination system, and then proves the traditional coherency of power system a special model of differential coherency through the theorems relate to. Two new notions of power system coherency are present, as well as the judgement of the notions. Finally, the paper demonstrates the usage of the notions according to the simulation and physical experiment of the dropping controlled parallel-connected two inverters.
