Abstract
A hybrid microgrid is an efficient technique to integrate renewable energy resources and allow energy exchange between ac and dc subgrids. Pf and QV droop controls are commonly employed in microgrid to deliver power demands while preserving voltage and frequency restrictions via interlinking converter (IC). When a microgrid is powered by renewable energy sources, due to the prevalence of impedance conflict traditional droop techniques offer an inappropriate response in power sharing. This study employs a predictive-based control scheme to ensure appropriate power sharing between both subgrids in the event of imbalancing on either side. Photovoltaic systems, battery storage, and a synchronous generator powered by wind turbines constitute a microgrid, which is connected via an interlinking converter. The MPC MPPT-based control approach dynamically dispatches power generated by wind and solar energy sources to the loads connected throughout the hybrid microgrid. The proposed control technique maintains power exchange between hybrid microgrids within an acceptable range, according to simulation and experimental results.
