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.

IET Renewable Power Generation, Volume 17, Issue 12, Page 2964-2977, 7 September 2023., 2023 This paper proposes an enhanced SMC control method for minimizing the NGV and THD in addition to compensating for unbalanced load voltage conditions simultaneously in a three‐phase four‐leg inverter. In order to verify the results of the proposed method, simulation results with MATLAB/Simulink are presented to confirm the effectiveness of the proposed ...

Three-phase primary control for unbalance sharing between distributed generation units in a microgrid [PDF]
, 2013 For islanded microgrids, droop-based control concepts have been developed both in single and three-phase variants. The three-phase controllers often assume a balanced network, hence, unbalance sharing and/or mitigation remains a challenging issue ...
