Controlled and decoupled distributed generation

Abstract

The paper presents application of the power electronics in a power generation systems dedicated especially for renewable energy sources. A stand-alone opera- tion of the power generation systems with DFIG is presented in the paper as an example of decoupled generation. Proposed control method and topologies allows to produce the fixed output voltage amplitude and frequency. The method bases on the output voltage vector components in the reference frame rotating with a synchronous speed. Also a PMG with power electronics converter is presented in the paper. A results from laboratory system tests are shown.
