Bidirectional converter for distributed generation with grid-supporting capacity

Distributed generation systems are growing, and their power converters and how they deal with the power flow when connected to the grid are key knowledge in this field. This work shows some technical and functional characteristics about a bidirectional converter, developed to assist the grid providing active or reactive power. The converter and control algorithms are presented, as well as a relation between the converter and synchronous generators, showing active and reactive power control capability. Simulation and practical results in a single-phase prototype demonstrate the system behavior.
