Patent number: 11979025Abstract: A dual-mode combined control method for a multi-inverter system based on a double split transformer is provided. For an extremely-weak grid, the method provides the dual-mode combined control method for a multi-inverter system based on a double split transformer. According to the method, the equivalent grid impedance at a point of common coupling (PCC) of one grid-connected inverter (GCI) in the multi-inverter system based on the double split transformer is obtained with a grid impedance identification algorithm, and the system sequentially operates in a full current source mode, a hybrid mode, and a full voltage source mode according to a gradually increasing equivalent grid impedance, thereby effectively improving the stability of the multi-inverter system based on the double split transformer during variation of the strength of the grid. The method ensures that the system can still operate stably in the extremely-weak grid.Type: GrantFiled: May 13, 2021Date of Patent: May 7, 2024Assignee: HEFEI UNIVERSITY OF TECHNOLOGYInventors: Xing Zhang, Ming Li, Zixuan Guo, Jilei Wang, Hailong Pan, Yang Wang, Qian Gao, Fei Li

Patent number: 11967825Abstract: A stability control method for a virtual synchronous generator (VSG) in a strong grid based on an inductance-current differential feedback is provided. A grid-connected topological structure of a VSG using the control method includes a direct-current (DC)-side voltage source, a three-phase inverter, a three-phase grid impedance and a three-phase grid. By controlling the VSG and controlling the inductance-current differential feedback, the method suppresses the oscillation of the output power from the VSG in the strong grid and implements the stable operation of an inner-loop-free VSG in the strong grid, without adding the physical inductance, increasing the cost of the filter and additionally providing a grid-side current sensor.Type: GrantFiled: June 29, 2021Date of Patent: April 23, 2024Assignee: HEFEI UNIVERSITY OF TECHNOLOGYInventors: Xing Zhang, Zixuan Guo, Shaolong Chen, Yang Wang, Hailong Pan, Qian Gao, Zhen Xie
