Abstract: With the adjustment of the global energy structure, the power system under the penetration of new energy has developed rapidly. In response to the frequency security issues brought by new energy to the power system and the influence of the state of energy storage batteries on the system frequency, this paper constructs a frequency response model for wind–storage joint frequency regulation to analyze the frequency characteristics of the power system under different operating conditions. On this basis, considering the influence of the state of energy storage batteries on the system frequency, a system model under the scenario of additional load disturbance is built; the influence of environmental temperature on the state of energy storage batteries is analyzed to explore the changes in system frequency under high‐ and low‐temperature conditions; finally, the robustness of the system frequency model under different wind speed changes is analyzed. The results show that when the state of energy storage batteries is considered in the wind–storage joint frequency regulation, the system frequency overshoot is reduced by 6.01%, the frequency recovery time is shortened by 3.476 s, and the steady‐state frequency error is reduced by 0.004; high‐ and low‐temperature environments will cause the frequency recovery time to be prolonged, with an overshoot of 16.30% in the 45°C high‐temperature environment and an overshoot of 52.66% in the −25°C low‐temperature environment; the lowest point of the system frequency remains above 49.6 Hz in the wind speed range of 5–15 m/s.
