The huge penetration of Distributed Energy Resources (DERs) can have a considerable impact on the frequency dynamics of bulk power grids. Most of the DERs connect to the distribution grid through Smart Inverters (SIs), and the IEEE-1547 provides provision for frequency-active power, P (f), droop settings for DERs to respond to the frequency dynamics. In this context, this work develops the co-simulation of transmission, distribution, and DERs to study the impact of P (f) droop setting parameters of SIs on the primary frequency response of the bulk power grid. The case studies show that the inclusion of SIs with P (f) droop can help enhance the primary frequency response. Moreover, the case studies also show that the choice of P (f) droop parameters (e.g., slope, dead-band) impact the primary frequency response of the bulk power grid, and proper selection of the droop setting parameters can aid in better primary frequency response of the bulk power grid.
