Due to various important features such as higher efficiency, reliability, stability and voltage regulation, DC microgrids are attractive options for supplying various DC loads. Moreover, several energy sources can also be directly connected to DC microgrid. However, most of the present loads are AC loads supplied by the existing AC lines. For achieving benefits of both ac and dc microgrids, these two types of microgrids can be interconnected to realize hybrid and meshed microgrids. These have great potentials to improve the performance of electric grid, loads and various energy sources. Due to the presence of dc system, the hybrid and meshed microgrids have higher power handling capacity and better voltage regulation capability as compared to the conventional ac microgrid. The integration of the electric vehicle (EV) charging stations, renewable energy sources (RES) and battery energy storage systems (BESSs) to the microgrid faces multiple challenges in power management and optimized energy transport. Advanced architectural structures for the hybrid and meshed microgrids would further improve the efficiency and reliability of the system. However, the involvement of more number of power electronic converters increases the complexity of network control operations. The hybrid and meshed microgrid enables various power flow paths in the electric grid requiring development of optimal power flow algorithms for continuous and stable operation of overall system. This special issue focuses on the development of architectural configurations and advanced control methods for the power electronic converters for hybrid and meshed microgrids.
