基于奇异值分解的含风电电力系统强迫振荡分析
The Forced Oscillation Analysis of Wind Integrated Power Systems Based on Singular Value Decomposition
摘要
Abstract
With the large-scale wind power integrated in power systems, the 3p-frequency periodic fluctuations caused by wind shear and tower shadow effects, may lead to forced oscillations, which seriously threaten the stable operation of the power systems. The frequency response to forced oscillations varies with the access point of wind power. To analyze the relationship between power disturbance access point and the frequency response on different observation nodes, a small signal model in frequency domain considering the dynamic characteristic of generator with governor, load characteristic and network structure was established. Then, the singular vectors of system transfer function matrix solved by singular value decomposition method, were used to analyze the distribution of forced oscillation component in nodes and the influence degree of power disturbance access point on the steady-state frequency response of nodes. Compared with the complex modes method, the correctness and validity of the singular value decomposition method were verified. Finally, on IEEE 39-bus system, the singular value decomposition was applied to analyze the influence of 3p-frequency periodic fluctuations of wind power on system frequency response. The results indicate the importance of a reasonable selection of wind power access point.关键词
