中文摘要：
随着新能源发电和新型负荷的并网接入,随机激励对电力系统的影响日渐突出,且电力系统中振荡现象时有发生,但由于不明原因而难以抑制.从频域的角度,发现了电力系统在随机激励下的广义强迫振荡现象,分析了广义强迫振荡产生机理.提出的广义强迫振荡理论指出：如果输入随机激励功率谱频段能够覆盖电力系统中某些较弱阻尼模式频率,就有可能引发较大的强迫振荡,振荡中包含这些较弱阻尼模式频率分量.采用电流注入法,在新英格兰10机39节点系统进行了计算分析,结果验证了广义强迫振荡理论的正确性.所提广义强迫振荡理论是对传统狭义强迫振荡理论的突破.
英文摘要：
With the increasing integration of renewable generation and new loads into power systems,the dynamics of power systems under random excitation is receiving increasing concern. Meanwhile,lots of oscillations occasionally occur in interconnected power systems,which are difficult to explain and control. From the viewpoint of frequency domain,the mechanism and fundamental theory of general forced oscillation in power systems are developed. It proves that the general forced oscillations may be caused when the frequency bands,observed in the power spectral density of random excitation,can cover the inherent frequencies of some weaker damp modes in the power system,and the general forced oscillation contains all frequency components of these modes. This new theory 39-bus New England Test System. The general forced oscillation theory. is verified by digital simulation in the lO-generator, oscillation theory breaks through the special forced
