Micro-grid for on-site wind-and-hydrogen powered generation

Abstract

The authors propose a micro-grid for autonomous wind-and-hydrogen power generation thus replacing such traditional fossil-fuelled equipment as domestic diesel generators, gas micro-turbines, etc. In the proposed microgrid the excess of electrical energy from a wind turbine is spent on electrolytic production of hydrogen which is then stored under low-pressure in absorbing composite material. The electrolyser has a non-traditional feeding unit and electrode coatings. The proposed DC/DC conversion topologies for different micro-grid nodes are shown to be well-designed. The prototypes elaborated for the converters and hydrogen storage media were tested and have demonstrated a good performance.

Alternative Energetics DC Microgrid With Hydrogen Energy Storage System

“…3) can operate in voltage stepdown and step-up modes that are required for the power supply system with a 600 V DC-bus voltage level. The previous experiments showed that this type of the converter ensures high efficiency at the rated power [25]- [27]. In stepdown (buck) mode, this scheme matches the classic buck converter (elements C1, Q1, D1, L1, and C2) with the series diode D2 on the output.…”
