| Abstract:High penetration of renewable power brings challenges to frequency stability. To solve this problem, one solution is to develop frequency control strategies for the renewable generation. It is also necessary to improve the frequency control capability of the system. The key parameters of frequency control determine the frequency control capability of the system, and the analysis of their influence on frequency response is the key to selecting proper parameters and improving the frequency response of the power grid. Based on the system frequency response model, the influence of key parameters of frequency control including inertia time constant, frequency control dead band and adjustment coefficient on frequency response characteristics is theoretically analyzed. The sensitivity of the key parameters is analyzed, and the influential level of the parameters on the indices of the frequency response is obtained. The Power System Analysis Software Package (PSASP) is used to verify the results with a 36-node system. The results can be helpful for the selection of frequency control parameters. Based on the results, the role of the renewable energies participating in frequency control is analyzed.
