FAULT RIDE THROUGH OF DC SOLID STATE TRANSFORMER IN MEDIUM VOLTAGE DC SYSTEMS

Drazen Dujic
2023

Abstract

Medium voltage direct current is emerging in distribution and collection networks and the network codes are under construction. This article introduces the MVDC network fault ride-through (FRT) requirement and the response of a DC solid state transformer is analyzed. A novel control of the DC SST suitable in the MVDC PV collection network is proposed. The controls of the boost MPPT converter and the isolated DC-DC converter include a normal operation mode and an FRT mode without any additional hardware circuit components. The performance of the proposed solution is demonstrated in simulation.
