Research on Control Strategy of Hybrid AC/DC Distributed System Based on Multifunction Power Electronic Transformer

Abstract

This paper mainly focuses on the hybrid AC/DC distributed system with multi-function power electronic transformer (PET) as the core component, and the hierarchical distributed control structure has been proposed according to the analysis about system characteristics. And then the algorithms and control strategies of regional coordination and energy optimization management has been put forward. The reliability and feasibility are verified through simulation eventually.
