A new multiple-input hybrid energy conversion topology is presented. The proposed topology is capable of combining different energy sources with different voltagecurrent characteristics, while achieving low part number and bi-directional operational. The Multiple-input converters have many applications such as grid connected integrated hybrid generation systems, fuel cells, micro grid-based tel...

In recent years, hybrid energy storage (HES) to increase lifetime and reliability extremely are used in renewable systems and microgrids. In this paper, a new method for determining battery and supercapacitor capacity in an isolated microgrid is presented. Difference between Generation and load power using discrete fourier transform is transferred to the frequency domain and by determining the ...
