Control of Bidirectional DC-DC Converter for Micro-Energy Grid’s DC Feeders' Power Flow Application

Concerns about fuel exhaustion, electrical energy shortages, and global warming are growing due to the crisis. Renewable energy-based distributed generators can assist in meeting rising demands. Micro-energy grids have become a research hotspot as crucial interface for connecting power produced by renewable resources-based system. The integration of micro-energy grid technology at load level has been focus recent studies. Direct Current Micro-energy-grids one major fields years inherent advantages DC systems over AC systems, such compatibility with sources, storage devices, less losses, modern loads. Nevertheless, control stability paramount constituents reliable operation whether generation or level. This article focuses on flow between feeders an autonomous grid. To achieve this objective, mathematical model classical strategy two proposed using conventional dual active bridge converter. objective is minimize element High-Frequency Transformer. Firstly, non-linear-switched converter generalized average presented. Then, these models used get small-signal linear so be implemented. method enables output voltage regulation while abstaining from high-frequency transformer's winding saturation. analysis endorses validity scheme. Also, system response changes varying parameters consistent. simulation results validate proposal's performance changing parameters.
