Experimental research on Automatic Generation Control Strategy based on Simulation

Modern power grid has more and more requirements for system frequency stability. In order to improve the frequency stability level of power grid, we need to do more in-depth research on the frequency control strategy of power grid. However, there is no simulation model and simulation platform that can be used for frequency control strategy testing. There are no effective ways to test and study frequency control strategies. There are limitations in traditional methods and field experiments. In this paper, the modeling method of AGC control system is proposed by means of simulation, including the model of AGC control of main station and the simulation model of terminal actuator of power plant. A typical model of regional power grid is set up. Through the experiments of generator tripping, it is verified that the frequency characteristics of the simulation grid are the same as the actual frequency characteristics of the power grid. The established AGC control strategy model can be used for comparative analysis of different control strategies. The method proposed in this paper is an effective research method and means for power system AGC frequency control.
