Power converters analysis in a renewable energy based hybrid system with hydrogen storage

This paper presents a hybrid system including a photovoltaic array, a wind turbine, electrolyzers, fuel cells and hydrogen storage tanks, in order to reliably supply a radio base station in isolated locations, where to make a grid connection might be quite expensive. The intermittent and variable energy produced by those different elements must be conditioned in order to fulfil the load demand and requirements. Power converters assume that purpose and their behaviour under different operating situations is simulated to demonstrate how effective they are, even when the generation conditions are intermittent and apparently not reliable.
