Research and Stability Analysis of Active-Disturbance-Rejection-Control-Based Microgrid Controllers
With the rapid development of microgrid technology, the microgrid projects are no longer limited to laboratory demonstration and pilot platform. It shows greater value in practical applications. Hence, the smooth interaction between microgrid and the main grid plays a critical role.
In this paper, a control method based on active disturbance rejection control (ADRC) is proposed in order to realize the seamless transition between grid-connected and islanding operation modes and stable operation with variable loads. It is verified by simulation that the proposed ADRC-based
method features better performance compared to conventional proportional-integral-differential (PID) control. Meanwhile, the stability of the third-order extended state observer (ESO) in second-order ADRC is validated by using Lyapunov stability criteria.
