Method and system for enabling heterogeneous frequency modulation resources to participate in primary frequency adjustment in echelon

The invention provides a method and system for enabling heterogeneous frequency modulation resources to participate in primary frequency adjustment in echelon, and the method comprises the steps: obtaining a plurality of frequency modulation resource characteristics, carrying out the classification according to the characteristics of the frequency modulation resources, and generating a classification result; determining the optimal application range of the frequency modulation resources according to the characteristics of the frequency modulation resources based on the classification result; different dead zones and difference adjustment coefficients are set based on the optimal application range of the frequency modulation resources, and a control instruction is formed; and controlling a plurality of frequency modulation resource echelons to enter a working state in different frequency modulation stages through the control instruction. The invention solves the problem that the existing primary frequency modu
