摘要研究了大规模风电接入情况下, 通过改进常规自动发电控制系统的ACE模型和控制器, 对风电场输出功率扰动引起的频率波动进行抑制。自然界风力变化的强随机性和间歇性导致风电场输出功率大幅度随机波动, 对电力系统的频率控制产生不利影响。为了削弱这种影响, 本文在自动发电控制系统的ACE模型中引入了新的控制量, 并在其控制器中引入了模糊PI控制策略, 根据频率偏移的幅度自适应调节PI控制参数。含风电的两区域系统仿真结果表明, 改进的AGC系统对风电功率扰动引起的频率波动具有较好的抑制作用。

Abstract：This paper improves the ACE model and controller of conventional AGC system to suppress the frequency fluctuation caused by wind power disturbances. The strong randomness and intermittence of wind forces result in the random fluctuation of wind power outputs, which will have an adverse effect on the frequency control of power system. In this paper, a new controlled variable is introduced into the ACE model of AGC system, and fuzzy-PI strategy is used to regulate PI control parameters of the controller adaptively according to the range of frequency offset. The simulation results of a two-area electrical interconnected power system show that the improved AGC system developed in this study can effectively suppress frequency fluctuation caused by wind power disturbance.

Key words： Wind power Automatic Generation control frequency control Area Control Error fuzzy-PI control
