摘要：
The high-frequency oscillation of large-scale renewable energy islanded transmission system through the modular multilevel converter based high voltage direct current (MMC-HVDC) system is increasingly prominent in recent projects. In this paper, a mathematical impedance model of MMC with different frequency-coupling characteristics is developed with consideration of the inner dynamic process of the primary main circuit equipment, control link delay, sequence component separation link, inner and outer loop control links. The mathematical model is simplified to determine the high-frequency oscillation mechanism caused by the integration of islanded renewable energy station into the MMC-HVDC system, which is that the control link delay, inner loop current feedback and voltage feedforward link format the high-frequency negative damping of the MMC-HVDC system. The key factors affecting the high-frequency impedance characteristics of the MMC are obtained. Based on the key factors, the suppression schemes of high-frequency oscillation caused by the integration of islanded renewable energy station into MMC-HVDC system are also suggested. The corresponding solutions have been verified in the PSCAD model and the high-frequency oscillation problem in the engineering sites of Zhangbei and Rudong renewable energy transmission projects of China through the MMC-HVDC system has been solved. © 2023 Automation of Electric Power Systems Press.
