Hybrid Microgrid Operation and Control Based on Predictive Control Strategy for an Interlinking Converter in Grid-Connected Mode

Increasing the usage of different AC or DC Distributed Generations (DGs) and loads led to the concept of a microgrid. A hybrid microgrid becomes the most effective and reliable solution to use the benefits of AC and DC DGs. A power electronic interface is used for power flow between AC and DC buses. There is required a proper control method for power sharing between them. This article focused on the predictive control scheme of the interlinking converter of the hybrid microgrid. In order to evaluate the proposed scheme of predictive control of a hybrid microgrid, the MATLAB Simulink environment is used. The simulation results showed that the suggested techniques properly share power between AC and DC buses. The suggested control strategy, in contrast, demonstrates its efficacy and superiority to the conventional PI controller.
