LADRC Applied for the Doubly Fed Induction Generator Connected to the Micro-grid

this paper focuses on the control of double-fed induction generator's (DF1(;) powers (active and reactive) when it operates with parameters uncertainties in the structure of micro-grid. The control of the powers, transfer between the machine and the micro-grid, is assured by adjusting the rotor parameters and is ensured by the LADRC controller (linear active disturbances rejection control). The latter estimates and compensates the internal and external disturbances, which can be resumed in the parameters uncertainties. The robustness of the chosen controller in this work (LADRC) is evaluated by comparing with the proportional and integral (PI) controller under different point of operation against the simulation results given by the software MATLAB/Simulink. The results revealed that the performances achieved by the selected controller arc more efficient than those of the conventional PI controller. This can be explained by the capacity of rejection of disturbances ensured by the LADRC.
