A new proposed hierarchy for renewable energy generation to distribution grid integration

Abstract

This paper presents a new hierarchy about the study of renewable energy generation, its transmission, energy storage and adding this power to distribution grid level. Simulation are verifying the feasibility and working. The main purpose of this study is to propose a feasible solution to replace fossil fuel energy sources to renewable energy sources without changing current working distribution grids setup. This paper will describe main components of this hierarchy including DC-DC converters, DC transmission, energy storage devices and grid integration. DC-DC converters are converting generated voltages to high voltages to transmit them on DC transmission line. Similarly a DC-DC step down converter is being used for step down purpose for using transmission line voltage to low level voltage for energy storage purpose and for grid integration on distribution side. DC-AC inverter is using old distribution grid signal as sample and converter DC into AC according to it. Simulation results verify the efficient working of all converters and completely stable system.
