摘　　要：电力系统的频率控制是确保电网安全运行的重要手段。然而,通信时延和负荷不确定性会降低系统的实时性,威胁系统安全。基于此,提出一种电力系统频率控制优化策略,并进行仿真实验。实验结果显示,在动态时延场景下,系统频率偏差减少了约4%,响应时间缩短了约20%;在极端负荷场景下,系统频率偏差减少了约30%,响应时间缩短了约25%。表明优化策略能提升系统的稳定性和健壮性。研究成果为提升电力系统在复杂条件下的稳定性提供了理论支持和实际应用价值。Frequency control of the power system is an important means to ensure the safe operation of the power grid.However,communication latency and load uncertainty can reduce the real-time performance of the system,posing a threat to system security.Based on this,a frequency control optimization strategy for power systems is proposed and simulated experiments are conducted.The experimental results show that in dynamic delay scenarios,the system frequency deviation is reduced by about 4%,and the response time is shortened by about 20%;In extreme load scenarios,the system frequency deviation has been reduced by about 30%,and the response time has been shortened by about 25%.Indicating that optimization strategies can enhance the stability and robustness of the system.The research results provide theoretical support and practical application value for improving the stability of power systems under complex conditions.
