摘　　要：针对间歇式能源的波动性和随机性使电力系统传统的调频控制模式无法适应的问题,对传统的调频模式做了改进,即在传统调频模型的基础上,调整一次调频参数,采用人工智能算法的AGC的PI控制器和动态的AGC机组的发电分配系数,并将间歇式能源预测误差计入区域控制偏差中。算例结果表明,通过MATLAB/Simulink仿真,改进的调频方式在系统功率大范围随机波动下的调节效果较好,更有利于系统吸纳间歇式能源。Because of the fluctuating and stochastic behavior of intermittent energy, the traditional frequency regulation in power system can not adapt to the new situation. Based on the original frequency regulation model, the traditionalmethod is improved in this paper. The primary frequency bias parameters were regulated, and PI controller using artifi-cial intelligence algorithm and dynamical generation distribution factors of AGC generators were used, as well as the prediction error of intermittent energy was calculated in extra ACE. The results show that using MATLAB/Simulink, theimproved frequency regulation method has better performance than traditional method in a wide range of stochastic powerfluctuation. And it is conducive to absorb intermittent energy.
