Abstract
This research presents the modeling and control of Modular Multilevel Converter (MMC) based multiterminal HVDC network to integrate wind energy based on permanent magnet synchronous generator (PMSG). Submodule capacitor voltage balancing and arm circulating current control were considered in MMC detailed model. One complete unit of PMSG for wind energy generation using detailed model was considered in this work to preserve harmonics characteristics which is ignored in the simplified current source based conventional model. Without placing the capacitance on the high AC side voltage of MMC, it developed the constant AC grid voltage for wind farm connection employing PI controller. Wind energy was controlled through field oriented control. It analyzed MMC controller performance under unbalanced and balanced faults at the connection point of AC grid. The complete system has been implemented in RTDS for real time validation. Besides optimum wind energy tracking, the results showed reactive power support and enhancement of the ride through capability of low voltage during fault.
