Zusammenfassung:	The invention relates to a wind-driven generator and diesel engine load coordinated frequency modulation method applicable to a high-permeability renewable energy micro power grid. The method includesfollowing steps: 1) establishing a micro power grid model containing a double-feed asynchronous wind driven generator, a diesel engine and a controllable load; 2) obtaining coordinated frequency modulation characteristics of various frequency modulation micro sources containing a high-permeability wind power micro power grid; and 3) obtaining a wind driven generator and diesel engine load coordinated frequency modulation mode applicable to the high-permeability renewable energy micro power grid according to the micro power grid model and the coordinated frequency modulation characteristics, namely, the double-feed asynchronous wind driven generator and the diesel engine preferably participate in frequency modulation, the controllable load participates in frequency modulation only when anabrupt change amount of th
