According to the environmental concerns, the utility of renewable energy is rapidly growing up. As wind power penetration increases, power industry tends to replace conventional generation units with the wind power resources. Modern wind energy conversion machines are not able to participate in frequency response since the machines are decoupled from the grid by back-to-back voltage based converters. In this paper, the coordinated control approach takes advantage of the fast response capability associated with electronically-controlled wind energy conversion, allowing the stored kinetic energy in rotational mass to release in order to provide temporarily inertia and primary frequency response (PFR) support. This paper investigates the impact of coordination of inertia, the PFR and combined inertia-PFR support between wind farms and conventional generators on the frequency response of updated IEEE-39 bus power system. The simulation results show the significant improvement in frequency performance with coordination between wind farms and conventional generators.
