Multiport Dc-dc-ac Modular Multilevel Converters For Hybrid Ac/dc Power Systems

Power electronics are mainly used in  Hybrid ac/dc power systems  to empower controlled energy exchange between various dc and ac frameworks. Multiport dc-dc-ac MP-DC2AC) converters offer the capacity to transmit energy between two dc frameworks and an ac system utilizing a solitary converter structure. Potential advantages like reduced energy conversion stages and a more compact station footprint. Until this point in time, constrained data is accessible on displaying, activity and control of MP-DC2AC converters reasonable for HVDC and MVDC applications. This paper fills this gap by introducing a summed up modeling and control system for two yet unexplored MP-DC2AC modular multilevel converters. In view of determined systematic models of inner power move instruments, a unique controller is recommended that permits autonomous control of port power streams while keeping capacitor voltages directed. Results are approved by broad time-space reproductions. A detailed examination between four diverse MP-DC2AC topologies is completed.
