IET Generation, Transmission &Distribution, Volume 17, Issue 19, Page 4248-4257, October 2023., 2023 An optimal negative sequence suppression strategy without phase‐locked loop (PLL) based on the control of clustered new energy power station is proposed. This strategy achieves effective suppression of negative sequence current during open‐phase operation without additional devices. Abstract In the context of extremely uneven sources and loads in China,

A control strategy of microgrid voltage source inverter based on self‐learning sliding mode control
IET Power Electronics, Volume 16, Issue 12, Page 1958-1968, 16 September 2023., 2023 In this paper, a self‐learning sliding mode control strategy is proposed. First, a nonlinear smooth function is used to design an expansion observer, which can estimate the expansion state of the internal uncertainties and external disturbances of the control system.
