To enhance the dynamic performance and robustness of the voltage control system of islanded microgrid inverters, a new control strategy combining integral sliding mode (ISM) control and composite nonlinear feedback (CNF) control is proposed. In ISM control, firstly, a new reaching law is designed to improve movement quality in the reaching phase by improving the power term and introducing the inverse tangent function. Then, to improve disturbance observation accuracy, a variable gain extended state observer is designed by improving the regulation mechanism of the state variables according to deviation control. Using the idea of variable damping, linear and nonlinear feedback are combined into CNF control. Specifically, linear feedback provides a small damping ratio for faster system response, while nonlinear feedback increases the damping ratio to improve steady‐state performance. Simulation results show that the integral sliding mode‐composite nonlinear feedback (ISM‐CNF) control strategy cam balances convergence speed and chattering better and achieves higher steady‐state accuracy than conventional strategies. Moreover, ISM‐CNF control has better robustness to reference voltage variations and disturbances caused by sudden load changes. Therefore, the ISM‐CNF control strategy can accomplish voltage control of islanded microgrid inverters quickly and steadily, effectively suppressing system disturbances and enhancing stability and power quality. © 2024 Institute of Electrical Engineers of Japan and Wiley Periodicals LLC.

In multi microgrid systems, frequency deviation in islanding condition is one of the major issues. Frequency deviation is not only due to the load changing conditions but also due to the present of different renewable energy sources in the micro grid and system disturbances. In such system, it is very difficult to achieve the satisfactory operating condition with the existing conventional PI/PID controllers. In this paper, new controllers are suggested to improve the deviation of frequency as well as to maintain the power flow in tie-line in island condition in microgrid system. The suggested controller uses the combination of PSO-GWO algorithm and hence known as hybrid technique, this technique is implemented in the work to obtain the optimal parameter of both PID and PI-PD controllers. To verify the effectiveness of the hybrid techniques, a microgrid system with different conditions is developed with the help of MATLAB/SIMULINK software and finally the implementation of the controller is carried out with help of this technique, the obtained results prove the ability of the techniques as it is successfully achieving the desired outputs.
