Seamless Formation and Robust Control of Distributed Generation Microgrids via Direct Voltage Control and Optimized Dynamic Power Sharing

摘要: Seamless formation and robust control of distributed generation microgrids are essential requirements to facilitate powerful flexible infrastructure in future smart power grids. Motivated by this objective, paper presents a structure for microgrid converters based on direct-voltage optimized dynamic sharing. The salient features the proposed scheme 1) minimum switching actions between grid-connected isolated systems minimize internal disturbances; 2) active damping performance converter voltage vector effectively reject both magnitude disturbances angle swings associated with mode transition load 3) high bandwidth direct loop modes improve response disturbance rejection performance. Theoretical analysis comparative experimental results presented validate effectiveness scheme.
