The imbalance of power between generation power and load consumption causes a decline in the frequency of the power system. The frequency deviation depends on the power of generator outage and the operating status of the system. The monitoring and control system of the power system will immediately implement the control solutions to restore the frequency back to the allowed value. Among these solutions, it is necessary to mobilize the reserve power of the remaining generator turbines to restore the system frequency. This article proposed a method for calculating the amount of load shedding considering the primary control of generator in a power system. The proposed method calculates the amount of load shedding to recover frequency to allowed value when the lack of generation source due to outage generator leads to overload in an electric power system. The effect of the proposed solution which was tested on a diagram of the electric power system standard IEEE 37 bus 9 generators proved the effectiveness of the proposed method.
