The Effect of Load Frequency Controller on Load Pickup During Restoration

This paper proposes a method to improve the frequency response of a power system during restoration. A load frequency control (LFC) scheme with a PID controller is used In the initial phase of restoration; the proposed control scheme helps to increase the amount of load pick-up. Presented method is capable of achieving better frequency response for a determined load step. The aim is to assess desired frequency response for different power plant. The proposed controller has been tested for different power plants, and simulation results show that the frequency controller can improve load pick-up.
