摘要：
This Paper puts the powersystem into an affine coordination system, and then proves the traditional coherency of power system a specal model of diffrential coherency through the thoerems 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.
