Inertial control methodologies for securing wind turbine highly penetrated power system

This paper comes under the fairly recent research trend of wind turbine generator participation in fast frequency regulation (inertia emulation) in coordination with conventional power system generators. At first, and with the attempt to unify the scattered control objectives in literature for highly penetrated wind turbine generation-based power systems, the paper portrays a collective control horizon for such systems that categorize various control objectives into layers and levels as well as interconnect them with each other. Then, four control techniques to provide fast primary frequency control as well as a power reserve for inertial response are identified to be the most common techniques used in the first 10 seconds of frequency excursion. Various variants of each control technique are presented, discussed, and compared.
