Efficient System of Power Flow in Hybrid AC-DC Micro-Grid by Implementation of Bidirectional Switched Boost Converter

摘要

In this paper, the efficient micro grid system is processed with the distributed power generation by fuel cell,wind and solar are in it such as AC-DC Micro grids and AC and DC Micro grids. Normally AC or DC micro grid undergoes multiple conversion phases with a limitation; to overcome this limitation AC micro grid is processed with the bidirectional converters in the conversions. A humble and instinctive method of frequency detection for a single-phase Synchronous Reference Frame Phase Locked Loop (SRF-PLL) is similarly executed using a filter compensator. The finite impulse response filter and fast period detector are processed in the system for PLL robustness and truthfulness improvement under several essential frequencies. Also in converter, the bidirectional full bridge CLLC is recommended in the dc distribution system for the galvanic isolation. The switch tensions are similarly considering for every devices of switching. In the direction of both power flow of AC and DC bus attained the unchanged voltage gain. The analysis of AC grid and solar/wind/fuel cell is deliberated using analysis of steady state to resolve various renewable sources, collaboration between loads and their optional control with the grid utility.
