In order to enhance the power system inertia situational awareness ability in high proportion new energy access scenarios and improve the power system stability.In this paper, we constructed a frequency response model of the power system using the equivalence method, analyzed the time and size of the maximum offset of the frequency, and clarified the influencing factors of the system frequency stability.The solution model is established with the objective of minimum inertia, and the innovative simulated annealing algorithm improved by genetic algorithm is used for the solution.Finally, based on the IEEE-14 node model to verify the method proposed in this paper, the results show that: at the moment of t=9.67241s, the system arrives at the maximum point of the frequency deviation, and the maximum deviation of the system frequency is 0.0688Hz. The minimum inertia of the system is from 25786300KW•S from the non-consideration of the new energy unit to the full unit of the new energy unit, 17345900KW•S.
