摘要：AbstractThis paper proposes a method to regulate the voltage output in DC sub-grid of a hybrid AC/DC microgrid by designing a model-based controller for bi-directional interlink converter (IC). A linear time-invariant (LTI) model representing the DC sub-grid is constructed by applying a step response in the IC. Then, the model-based controller of IC is made by forming a closed-loop system based on the obtained LTI model and a PID controller. To get proper values of PID gain in the closed loop system, an optimization problem needs to be solved. The result shows that using the model-based controller and PID gains from optimization, the modified system has better performance than the original one.
