This paper proposes an analytical control strategy that enables distributed energy resources (DERs) to provide inertial and primary frequency support. A reduced second-order model is developed based on aggregation theory to simplify the multi-machine system and facilitate time-domain frequency. . Primary frequency regulation refers to the process in which power plants adjust their output through the automatic regulation of the speed governors when the system frequency deviates from the nominal value, in order to stabilize the system frequency. Because of the wear and low-utilization cost, gener-ators are not proper to deal with the load frequency control alone.
