Green Hydrogen Long-Term Storage Integration into DC-Microgrid Bus Operations

Hydrogenis an essential part of future modern energy systems aiming to solve the energy crisis and to supply clean, low-carbon energy securely and efficiently. It has high calorific value, zero emissions, easy accessibility, and the flexible characteristic of mutual conversion with water and electricity. By integrating hydrogen storage with renewable energy sources, local hydrogen production can be achieved, which decreases the expense of hydrogen production and transportation. The integration that we're discussing here is crucial in aiding the process of decarbonizing the power system. In this paper, we introduce a reliable and stable Direct Current (DC) microgrid system incorporating wind, photovoltaic sources, and an energy storage system. This system operates based on a mathematical model of each interface unit and leverages the operational characteristics of an electrolyzer.
