摘要：In this work, a method for hierarchical hybrid linear-nonlinear microgrid control is proposed based on nonlinear primary control and linear secondary control. The nonlinear controller is an Extended Feedback Linearization method, and the linear controller is a PID structure. The proposed method is evaluated in several scenarios to validate its performance to disturbances and island operation mode. To this end, three units of distributed generation are included: Photo-Voltaic Energy Sources, Energy Storage Systems, and Small-Hydro-Power Sources. The results are simulated over a DC microgrid that contains three different distributed generation units with disturbances and island operation mode. As a result, the proposed approach’s robustness is validated for several cases, where the advantage of a hierarchical linear-nonlinear structure is shown.
